Sorry, yes, I was keeping my comments in reference to the Mini.
From the HD model upwards, there is a Holdout Matte input.
There is an 80% price jump from the Mini to the HD though so it increases the cost of a multi camera setup considerably but it is still very good value for money for anyone needing the facility.
With some thought, dual background and foreground elements could be coaxed out of Unreal.
 

The Ultimatte 12 HD Mini in particular is very interesting.
As they all include frame stores so they can be used 'in line' as it were with a camera, then with the 12 HD Mini being €500, it brings the cost of a four camera fixed virtual set system down to well under €3000 depending on what ATEM you get to switch them with.
OK, it won't be an all singing all dancing system with tracked movements as the background will be pre-rendered and static, but for a lot of applications that will be perfectly acceptable.
Incredible value for money.
 

Blackmagic has released not one, but four Ultimatte hardware keyers!
https://www.blackmagicdesign.com/products/ultimatte
And from the sound of the blurbs, the technology is truly state of the art.
It will be interesting to see whether they're really as good as they claim.
I hope they are.

The GH5 has been an iconic camera.. very close to a GH6 too. I think the point of that video is, when exposed and edited properly, you can get great results with any of them. I've purchased some of these old cameras (usually with a lens); then I sell the lens and get the camera for VERY cheap if not FREE or even make money in some cases. I like the challenge of doing great things with low-end gear rather than getting the most expensive gear with the expectation of fantastic results. That's just me, and I don't shoot professionally; so, there's that too.

I’ve owned a number of those cameras (GH 1. NX1, BMCC 2.5k). I would say that the GH5 is a great low total cost of ownership camera.
It’s 10bit with a decent bit rate for about $750 used.
Maybe that’s more than people would consider cheap, but it is hack and hassle free with a broadcast quality image.
So have we had access to great low cost icing images for a long time?  Sure, but each had it’s challenges and flaws !

Cmon. Go to the Vimeo site and download the original - it is 8K. The same 8K video was uploaded to YouTube. I have no control over what YouTube streams.
I do not like being called a liar, particularly when  I went out of my way to post on Vimeo so folks could download the un-recompressed 8K original.
It is people like you that steer away posters.
 
 

I mean if you buy RSMB and have time to kill waiting for motion blur to render, you can just add it in via post. Also gives you the option to use a higher shutter speed as a “built-in variable ND filter”

@Andrew Reid I have been a member of many forums over the years and really hope this one doesn't end, IMO it is the last place on the Internet where someone can still go to have deep technical discussions about all things video production related. So, I do hope you make the decision to keep the forum running, and my contribution to what I think will help it do so is below:
Remove the Edit Post time limit - This is my only technical complaint with this forum, no other forum I have ever been a member of has this. I know awhile back you had a problem with spammers editing some posts after posting, but I am not sure this was the right answer. Maybe you could do like some forums, after a member has reached a certain level of posts then the limit is removed or at least raised to 24hrs. Many times I will find a typo in my post or want to write some more after reading it and there is no way to edit it. So either I just skip it (usually) or write it in a follow up post (looks like I am overposting to me). Cater to Photography as Well - I know this forum is micro-focused on video production, but these days many of us myself included is a hybrid shooter. I rarely post anything photography related here simply because it caters so heavily towards video. The reality is though, most of the cameras we talk about on here also have great photography features. I think you would attract new members if you also started covering more depth in the photography area. Maybe not you personally but making the forum more attractive for photographers somehow. I think Fred Miranda is the last really deep photography site out there. Also, it is so much more work to produce a good video that you know will immediately get picked to pieces by other forum members 🤣 vs taking a good photography image and talking about the technicals behind it. Members love showing their work, having a gallery where we could post photography as well would definitely increase the forum's appeal in my opinion. That gallery could also let members vote on their photo pick of the week or something like that. Sub Forums - I know you just got rid of them and this will probably be an unpopular recommendation here, but when I look at every successful forum that I have contributed to (Fred Miranda, AutelPilots, CanonRumors, DodgeDurango.net), they all have one thing in common; they force you to pick a sub forum. I know many subforums is where things go to die, but that's because most forums have too many sub forums. A few big parent forums would organize things better than many sub forums. For Example, parent forums could be (Photography Talk, Video Talk, Drone Talk, Gear Reviews, Classifieds, Editing / How To, Show and Tell). Those are just examples. AutelPilots is very well laid out and has a lot of interaction in the subforums mainly because new posts in the sub forums are surfaced in the latest threads section helping everyone find new posts regardless of subforum. Advertising - I know you need revenue, and I know everyone dislikes ads, but I would rather the site have ads then get removed. I am not sure how ads work, maybe you could be selective with who can advertise on your site, but I know the site has to generate revenue as well. Most of the forums if not all of the ones that I listed have ads and the members still come. Classifieds - I don't know if your classifieds section currently charges to post something for sale, but I know Fred Miranda's site does. Its a very nominal fee ($5 I think) but its still better than nothing. Obviously that comes with its own headaches (scammers never sleep), but I would trust buying or selling to a well known member here than eBay any day. If you already charge for classifieds then you can ignore this suggestion. Educational - This forum has vast breadth and depth of knowledge when it comes to video and probably photography as well. But very few educational posts are made, probably because YouTube already has literally everything you could ever want to know. But I think an educational section here would be very helpful. The problem with YouTube is most of the time the viewers ask follow up questions that don't get answered in the comments. I am a member of AutelPilots and my instructional posts get more interaction than any other posts that I make there.  People always want to learn something new, and I feel like at the moment this isn't the site people go to to do that. Gear Review - I think every member here watches gear review videos. We all know most of the YT reviewers are heavily biased and most of them don't actually use the equipment to make a living; but, there are a few very good ones that I do watch. MonkeyPixels, Gerald Undone, and a few others I do value their opinions. Since it would not be cost effective and redundant for you to try to match the "professional" gear reviewers on YT, maybe you could curate instead....find the one single best review that you consider the most thorough and accurate and post that one video here, where members can discuss it in greater depth; also where you can provide your own deep insight into what you thought of the review and the gear being reviewed. Social Media - We all hate it but we all use it in some way, I use it just as an alternate gallery posting location to show my past video and photography work and also because my clients typically go there to reshare their content from my social media to theirs. I know you hate it as well, but I think you could use it to your advantage without it becoming and bottomless endless waste of time. On my website I use software so that everytime I post a blog post on my website it automatically posts on all of the social media platforms as well. Maybe something like that would reach more people and attract new members. Other Forums - I am pretty sure you have already done this, but I think a review of other top forums might also give you more ideas on what it takes to get members these days. The most successful forums that I see are usually the ones where members turn to when they need help or want to learn something from someone else that will most likely have an answer (i.e. DodgeDurango.net is the biggest forum for Dodge Durango owners and where nearly everyone goes when they want an answer to their specific problem). AutelPilots is very specific for Autel Drones and they get tons of new members every time a drone is released by people trying to learn everything they can about Autel drones.  Learning and education IMO are the biggest and best performing categories on YT and rank the highest on Google searches but I don't feel like this site currently caters to that category. Show and Tell - I mentioned a photography gallery previously, but maybe a video one as well. I always hesitate to post my content here because it could be considered spamming or self promotion, but if you had a section where members could post their work and answer any questions other members had about how it was created, the gear that was used, the technicals behind it, how it was edited, etc...that would be great. Obviously you would need to keep spammers out, so maybe the gallery sections could be read only until a member reached a certain posting level (similar to Fred Miranda).  Pinned Posts - I don't think they are a bad thing, I do think they shouldn't be more than 3 or 5. This is where subforums would help as well. Great information can get buried in this forum, pinning 3 or 5 posts of what you consider the top post or most relevant information at the time in the sub forums could be conversation starters, could be instructions for newcomers, could just be very useful information that might answer a question for new users visiting the subforum. Metatags - Not sure if members here would use them, but metatags really help with searching posts. It can be hard to find information on any forum, but if you allowed for a metatag field (just like metataging photos), it could make searches easier if members used them. Instead of having to type them, they could be easily clickable right before you post. Here is where I could rant about the current state of things where no one wants to read more than 180 characters, everyone is just using their cell phones so things are in a state of decline, people don't want to read, or type anymore and just want a YT video that spoon feeds them, etc. etc, but its all been said before. Those are definitely all uphill challenges and they won't get any easier but here's to hoping this site can overcome them. As other sites fold up or go under, maybe that in the end would be a good thing for this site as those members look elsewhere for an outlet.
I think at the end of the day this site has currently narrowed down its focus to a very small niche of users (video content producers endlessly pursuing the absolute best image quality possible by all means necessary) which is a turn off to new members who might just want to know what that exposure triangle thingy is, or the short answer to how to get started in Davinci Resolve.
Maybe your intent is to keep members like that off of this forum, but I think if you want to grow the forum you have to somehow find a way to balance what the general population is looking for with what the absolute purists are looking for as well. 

We have evolved into a dangerous form of media that's for sure. It's addictive, truth bending, ADHD and heavily sponsored.
Thinking of starting PhoneRaw.com which will try and get people to take more artistic shots with smartphones and learn the whole workflow of raw, both for stills and video.
If it is time up for traditional cameras (for me at least) then you have to know when to step aside and let the Geralds and Fros take over because you know then it is a bit of a lost cause and not what it was in 2014.

Developer options can be enabled so will see if it can be rooted.
You could argue this is what the back of most cameras should look like in 2022.

Speaking of attempts to bridge the gap...

This definitely should have had more legs than it did!
Lovely huge OLED screen. Full version of Android. SIM card slot.
It was priced crazily high when it came out and photographers stuck their noses up at it because it didn't have a joystick.
Normal people just couldn't afford it or justify it.
But I reckon if they had kept this concept going and made a new slimmer mount than NX, with some nice lenses to go with it and full frame sensor, this would have been a long term winner from Samsung.
That QX thing was definitely ahead of its time.
I can see why nobody bought it though.
Not good enough for enthusiasts. Not slim enough for consumers to pocket on a night out.

Panasonic announcing that they are now officially exiting the sub GH6 market completely is the official end of that era.
Their rationale is that anyone wanting to take high quality photos and videos will now buy a €1200 smartphone.
I'd sooner have a €1000 camera and a €200 phone but I'm not the market so I can see their point.
They caused this themselves by still even now having terrible integration with phones when the writing has been on the wall for years about how people would make and share imagery.
 

Hello everyone.
Forum is 50/50 sharing EOSHD with my content. So half the traffic goes to posts on the forum and half goes to my articles and content.
I would like to make some changes to EOSHD to make it more sustainable and grow again after a difficult period.
1. Definitely want to keep in touch and talk to my mates here on the forum. So not going to close the place down or suddenly let it go dark. How do people feel about a Reddit group or a Discord server, which are more smartphone friendly and a bit more about realtime chat and problem solving compared to a thread on a forum which may stretch over many pages and takes a lot of time to delve into? Maybe a better medium for lighter discussions and chat?
2. Financial side of EOSHD is not good at the moment. The forum might have to make way for the blog to put the attention 100% on my content. I can't see a viable way to make money from the forum. I don't think I want to put advertising everywhere either. If you can suggest a way to fund the forum and keep it going, I'd like to know your thoughts on that.
3. Small number of regular users are creating most of the content. We need to grow. Any ideas related to this very welcome. I can't really get my head around it. A very busy forum has crossed into that dangerous territory where a very small minority of regular users are making 99% of the posts. We need a more diverse range of topics and to not have the few interesting pieces flooded with 20 pages of armchair opinions 🙂
4. How the forum shares the domain with my own content needs to change especially on smartphones. If anyone can suggest new forum software that integrates seamlessly with a blog I am all ears as cannot seem to find any at all.
5. If forum is to come to an end after 11 years, it will because all replacements, shake-ups, redesigns and all ideas are exhausted and it becomes financially unviable for me to run it. I didn't agree at all with the way Cinema5D suddenly dumped their forum. All that info and all those posts in the bin. I didn't know what the rationale was behind it at all. Selling it to Mitch at Planet5D was a complete dick move. People (and their opinions) are not pawns to be traded around for money.
So I am all for constructive criticism on how we can make the forum grow again, be more interesting again and be financially viable.
How can we get some of the members back we lost?
Why are they not interested in posting here any more?
Is the general topic of cameras and video in decline?
And let's look to the positives of this place as well.
What works best? How can we play to our strengths and be relevant?
Over and out.
Andrew

I looked at various Android options before I went with my iPhone 13 with a view to the photo side, but in the end decided I would rather stay in the Apple ecosystem.
Not because I’m a fanboy (I prefer to buy unbranded products whenever I can and don’t like paying a premium to simply be a walking billboard) but rather because it works for me.
I went with the 13 to replace: an 8, a compact everyday camera and a dedicated drone controller.
I prefer the convenience of a phone as my every day camera, but the downside is the ergos/handling/use ability which definitely isn’t as nice as even a small ‘proper’ camera.
Still a long looooooong way off any kind of ‘phone’ taking over my pro needs and unlikely within the remainder of my career, but all that ‘stuff’ you speculated about Andrew will come because that’s where it’s headed.
It’s not just phone tech that is hurting actual ‘real’ camera budgets and development but stuff like AI. Perhaps even more so, ie, what is becoming possible with any old shitty footage. Or even no footage and the whole thing is fake…
It’s not going to take over and dominate for the 10-12 years I have to eke out a living, but I do think the photo industry (as we know it) especially is changing. That’s just reality and either adapt or die, or find a niche.
If it changes quicker than I anticipate, I’ll just start playing the retro card 😎

I thought that gyro would allow the camera to eliminate the warping as it would know the focal length and the cameras direction, but it seems to not be so.  That was literally the only advantage of gyro stabilisation over EIS.
I'd conclude that gyro is worth trying in post to see if it does better than EIS, but doesn't seem to have any advantage.  Both are last-resorts compared to IBIS / OIS, or physically controlling the camera with a gimbal, tripod, monopod, slider, crane, jib, etc etc.
(Disclaimer...  the below might sound harsh, but it's directed at the theories you're presenting, not you!  Hopefully my comments are useful and informative and correct some of the staggering misinformation floating around).
That's nonsense.
The data coming off the sensor is RAW - it's whatever the resolution is x the bit-depth x 3 (RGB channels).  
I think that Osmos and GoPros have the best stabilisation based on two factors - 1) they have fixed lenses and can tune their algorithms based on that, and 2) the entire success or failure of those products rests on how well they implement this feature.
That's also partly nonsense.  Man, the internet really doesn't understand WTF is going on with stabilisation.
I realise that manufacturers measure stabilisation in stops.  This is complete marketing crap - it's correct but irrelevant.
Think of the suspension system on a car.  The tyre follows every tiny bump on the road and the body of the car doesn't want to feel any of those bumps.  The goal of the suspension system is to connect the two but without transmitting the shake from the road to the car.  It's not a perfect parallel as there are differences between these examples, but it's good enough for our purposes.
The cars suspension system can be viewed in two scenarios.  1) how well it smooths small bumps, and 2) what the maximum bump size is that it can handle.
In the first scenario, you're driving down a road and there's a small pothole.  You drive over it, you hear a thump from the tyres, but feel almost nothing in your seat.  This is a reduction in the vibration, and in cameras, this is measured in stops.  It is the ratio of how much vibration goes in vs how much gets through the mechanism.
In the second scenario, you drive up a large curb.  If you're in a small city car, the tyre flexes, the shock goes all the way in, but the wheel hits the end of the shocks and sends an enormous thump up into the car, sending you and the contents of your car flying.  If you were in a huge off-road 4wd, you would hear a thump but the tyres and shocks would have enough vertical travel to absorb it.  You would still feel it to some extent, but it wasn't a disaster.
The second scenario is what you're seeing in your OIS/IBIS mechanism when you see the footage still have shake.  This is what separates small sensors from larger sensors - it's the amount they can travel, not the "stops" of IS.  The sensor simply runs out of travel and can't move far enough.
The math is very clear.  Take 5 stops for example, that's a reduction of vibration by a factor of 32x.  So, you move the camera by 32 pixels but the image only moves by 1 pixel.  You move the camera 50% to one side, and the image moves by 1/64 of the frame - in 4K that would be 60 pixels when you moved the camera almost 2000 pixels....and that's only 5 stops. 
This is why the stops don't matter.  The issue is how far the camera can move the sensor.  Larger sensors probably don't have as much room to move as a smaller sensor.  This is one reason for having a MFT camera the size of a FF MILC - to accommodate this mechanism.
The other biggest challenge is the wobble of IS (both OIS and IBIS) on wide-angle lenses.  This is a problem because spherical lenses are, well, spherical, and sensors are flat.  In terms of EIS, it's essentially a complete fail on behalf of the manufacturers to compensate, as GoPro and DJI have shown by doing it properly.  I looked at a package that corrects lens distortion in post (and also does things like RS correction and flicker elimination) but didn't buy it as it was closer to $1000 than I would have liked, but it's possible.  I could even tell you the math, but I haven't worked out how to implement it yet, unfortunately.  Resolves EIS pipeline isn't designed correctly to do it.

The R5 has hands down the best IBIS that I have ever used, I shot handheld a few shots with a 70-200 at 200mm and it was incredibly stable while filming closeups of people as a B-cam; so I do think modern IBIS systems can equal or be better than the BM gyro results. The difference for me is that when IBIS fixes instability there is no weird jitter or warping that I saw with the gyro results...at least not with the longer lenses (35mm and above).
The other benefit  of IBIS vs gyro is there is no cropping required...with IBIS what you frame is what you get, with post stabilization and gyro stabilization you have no idea ahead of time how much cropping will be needed. For my particular niche in the industry (fashion), it is very important to not have to crop because the crop could be in the worse possible place (middle of the model's head for example), rendering the shot unusable. Just because it shoots 6K doesn't mean you want to leave tons of room around every shot and frame differently to accommodate post cropping later; sometimes you need the exact composition that you shot.
Based solely on the video above, I think gyro stabilization is a lot like post digital stabilization....very good for certain types of movements and very jittery for others; whereas IBIS is excellent regardless of the movement.
DJI's Osmos and GoPros have the best In Body Digital Stabilization (IBDS?) out there. The working theory is that because the data rates are lower due to the smaller sensor, it takes less processing power to stabilize them (and other action cameras) than the larger cameras which is why their digital IS works so well. Another theory is that the sensor is simply larger for regular IBIS systems so the IBIS naturally will have to work harder to stabilize it. The GH5's IBIS for example blew away the FF competition for years in the IBIS department.
Manufacturers typically rate their IBIS system based on stops of light. For example, the R5 according to Canon has an IBIS rated at 8 stops of light...the highest in the industry for MILCs. Most manufacturers are rating their IBIS systems around 3-5 stops of light. I think the S5 was rated at 5 stops.  Not sure who invented light stops as a measure of IBIS performance, but it is the standard now. 
You can read more about how it is measured here:
https://www.canon-europe.com/pro/stories/8-stops-image-stabilization/
I will say, after this past week, the R5 without a doubt has the best IBIS I've ever encountered in a FF body.  I could hand hold at 200mm and make it look like I was on a tripod for an extended length of time; very impressive in my book.

I have gone full circle, I used to shoot everything from a tripod, gimbal, or monopod; mainly because I started out shooting real estate photography and video. As soon as I started working with bigger projects and faster moving events stabilization equipment felt like a crutch that was holding me back; even the monopod started feeling clunky and too much fiddling; by the time it was the right height, pointed in the right direction, and the camera was ready, the moment had passed.
These days I still have the monopod in the car but haven't used it in over 2yrs, I bring the gimbal to most shoots but usually either don't use it or use it only for a few min of walking shots, and the tripod I do use religiously for runway shows and long form static work. For everything else I shoot handheld. 
One thing I never do handheld though is try to walk; Other than GoPro, I have yet to see a single IBIS system that impressed me when walking. To me, if you are going to walk with the camera you need a gimbal, no exceptions. GoPro of course still has the best in body digital IS that I have ever seen, but they can get away with it due to the tiny sensor.
This is why I still say no IBIS system (other than GoPro) truly works when walking, no matter how many stops of light the manufacturer claims.
 
I had hopes that I would be impressed.....but I wasn't. The handheld static scenes were ok; about even with IBIS and about even with post stabilization; but the walking scenes were terrible as usual. Way too much warping, and jumpiness; it was obvious where the gyro stabilization was trying to fix the footage. I will be truly impressed when any IBIS or post stabilization can make a gimbal shot indiscernible from a handheld walking shot for the average videographer.
There are exceptional videographers who can shoot handheld without IBIS and without post stabilization and make a walking shot look great (at least for a few seconds to a minute), but they are the exception. Personally, I am always trying to improve my handheld technique because handheld is by far the most freeing while also the most challenging.
Shooting with the C70 handheld has greatly improved my technique, now when I shoot with a camera that has IBIS like the R5 I find myself shooting with much more stability and not needing any post stabilization.
 

The worst is stabilizing in post when someone is (not so carefully) walking with the camera. Everything just rhythmically blurring for a fraction of a second. It shows especially when there’s a lot of trees, traffic signs, etc in the frame.

Yeah, I suspect that it's often under the threshold of what is perceptible.
I also have a theory that this threshold is getting higher over time as people slowly get used to cameras that expose with SS.  Your comment about compression from online platforms is an interesting one, as, YT in 4K has more resolving power than basically any affordable camera had a decade ago, so that's actually gone through the roof, but peoples perception has dulled more than enough to compensate.
I've actually gone the other way in my work - I used to shoot quite dynamic shots and stabilise in post a lot, whereas now my shots are much more static and I basically don't stabilise in-post at all.  This forum used to be full of people talking about motion cadence, which despite never really getting a good definition was a pretty subtle effect at the best of times, and yet now people seem to be comfortable with the blur not matching the cameras movement, which I would imagine would be an effect at least one or two orders of magnitude more significant than motion cadence.
I also find it amazing that people have adjusted to 4K being cinematic, when even now many cinemas are 2K, and every movie (apart from those on 70mm) basically had 2K resolution by the time you saw it in a theatre.  
How perception changes over time!

That is a very interesting phenomenon, and makes perfect sense when you think about it.....but I think in the real world it is nearly impossible to see in a typical scene. Your test scene had a lot of sharp edges and detail combined with a lot of shake and post stabilization; in a typical shooting scenario the camera is farther away from the subject, there's few if any sharp edges, and the camera is typically also moving in some visible direction; combine that with compression from online platforms and I don't think it would be discernable at all.
The biggest problem I have with post stabilization is trying to balance the warping effect that post stabilization adds to certain scenes especially when shooting with wide angle lenses or the motion you are trying to fix. For me, I am more trying to smooth a too sudden motion more so than actual camera shake. When using it to smooth out a start or stop in motion it is quite effective but sometimes I have to try all 3 options in DR before finding one that looks natural.
The one place where I think this phenomenon would be perceptible nearly always would be shooting detail shots for real estate. In real estate videos though you nearly always use sliders or gimbals for that very reason....too many sharp straight edges that would make any camera shake, post stabilization, or horizon tilt very apparent.
I think at the end of the day nothing beats true stabilization equipment, IBIS, Digital IS, and Post stabilization are all just tools to get you "close enough" when "close enough" is acceptable.

I think i am gonna use gyro stab to some degree but not 100% cos I like the handheld look, just to smooth it out. On some other particular shots I might use it more extensivly. I would also try using a gimbal with a gyro to get it as smooth as possible as I hate that robotic walking gimbal look. Or I would just use my air2s for those perfect floating camera shots. Dunno, need more experimetns. The softwae is just getting developed (I use with gyroflow for now, but I hope either Blackmagic will add support for Sony or the former will produce their promiced plugin so the workflow becomes more intuitive and simple). If I had to choose which one to get - stable footage or motion blur, I would choose stable footage, if that what I need. Some times you must have a motion blur. Just prioritize what you need.  

IBIS and OIS in no way can deal with the shakiness of walking with the camera. But gyro stabilization alone can.
Here is a gyro-stabilized 4K video shot with the BMPCC6K in 6K BRAW (no IBIS or OIS), which has handheld static shots and walking shots:
 

If you have 180 shutter and shake the camera then your images will have shake and motion blur.  This will look normal because the blur will match the shake - if you shake / move left the blur will be horizontal and the size of the blur will match the shake / motion in the shot.
If you stabilise in post, you remove the shake but not the blur.  If you stabilised in post completely so that the shot had no shake then it would look like a tripod shot because the camera movement would be gone, but all the blur would remain, so a stationary shot would blur in random directions at random times for no conceivable reason.
This is a test I did some time ago comparing OIS / IBIS vs EIS (stabilisation in post is a form of EIS).  The shot at 25s on the right "Digital Stabilisation Only" shows this motion blur without the associated camera shake.
The IBIS + Digital Stabilisation combo was much better and is essentially the same as OIS + Digital Stabilisation.  
The issue here is that people using IBIS or OIS often have all the stabilisation they need from that, so the gyro stabilisation is aimed at people who have neither.  This "blur doesn't match shake" also happens in all action and 360 cameras when they shoot in low-light and their auto-SS adjusts to have shutter speeds that include blur (which is why I bought an action camera with OIS rather than EIS).

There is an R5/R6 user experience thread so I figured it was safe to start a Panasonic S5 user experience thread.  I've only shot with it for a few hours, mostly setting up (and learning) the menus and I know there are already endless YouTube reviews, but I thought I'd share my thoughts on my experience so far; completely unbiased, unsponsored and as someone who will use this camera for everything from music videos to weddings and if all goes well I might even use it for photo shoots.

Since there is so much that I like about this camera I've decided to just put my dislikes first because it is such a short list.
The Grip - This is my biggest dislike. holding the camera is so uncomfortable. The grip is really shallow and the strap mount sticks out and digs into your hand when you are holding it in a landscape configuration. Not so much a problem with video for me since I use the back display, but using the viewfinder for images is very uncomfortable. I'm going to try getting a dual battery grip to see if that improves it. The R6 by comparison feels like it was custom molded for my hands. The Lens Mount - I knew this going into it, but there are so few native Panasonic lenses for this camera that I will have to use an adapter which I hate doing. I know more lenses are coming but they are very expensive and everything I've read says the Sigma versions focus very slowly. I would love a Voigtlander fully manual 35mm lens for gimbal work like I have for the GH5. I have no idea yet what I will do for photography or if I will ever trust this camera for paid photo shoots. The Battery - I don't understand the battery at all. It fits the GH5 and has contacts for the GH5 yet for the S5 the contacts are on the other side? Why didn't they do what Canon did and simply make a higher capacity battery with the same contacts?  Not only are spare batteries impossible to find right now, this means all of my GH5 batteries won't work in this camera....so annoying. Ok, short list over now lets get to the stuff I care about that made me realize this was truly the camera for me. I first ordered the R6 and returned it (horrible user experience for my needs) so I am going to kind of compare my experience with the S5 to the R6 since they probably kind of are targeted to the same buyer and since it is hard to ignore the Canon hype machine even when you know about the R6's overheating issues. 
No Overheating - Ok we all know that but I had to put it out there anyway. This was the number one reason I returned the R6. The S5 on the other hand shoots glorious 4K until the card fills up (some limitations of course for 10 bit and 60FPS but it does have unlimited modes). Even if the R6 didn't overheat you would still hit that 30min limit and every single 4K mode overheated. Dual Slot Video Recording - The S5 gives me every option I could want and even a few I don't care about. The R6 will only record to a single slot. Electronic Level Meter - The S5 has it....of course, and it actually stays on while recording video. For some crazy reason the R6 disables the electronic level from showing on screen while recording video. XLR Audio Module - As annoyed as I am at Panasonic for the battery situation, the XLR module from the GH5 works with the S5 so all is almost forgiven. The R6 of course has nothing for XLR. I tested the module today, the S5 recognized it instantly and the audio was perfect. Free VLOG - Ok "Free" is a very generous term, but it does not cost extra. And this is real VLOG not some flavor that just flattens the profile, unlike the R6 which currently ships with CLOG. Canon said CLOG3 was coming in the future, but who knows if it will actually include the R6 or when "the future" really is. Body Quality - The S5 actually feels slightly lower quality than the body of the GH5, but that could be because it is lighter and smaller. Regardless, the quality feels way better than the R6. Sync/Desync Photo/Video Settings - It took me a long time to find, but it is possible to separate the photo and video settings and you even get to pick which ones stay synced with the other. When running and gunning you want shutter angle, VLOG, etc for video and shutter speed, Natural profile, etc for photos. You can set it so that they are completely separate, not all cameras let you do that and even the R6 did not let me pick which settings to keep in sync (i.e. keep just ISO the same between the two).  Dial Position - It is great to have the video mode and Manual photo mode side by side on the dial. The R6 had them at literally opposite ends of the dial....very annoying. Dedicated Buttons - There is a dedicated ISO button and a AF/MF switch on the lens. The R6 had neither. I use the AF / MF lens switch all the time, its the fastest way to be 100% certain all of the AF stuff is off, especially if you are switching between photos and video. Video Footage - The footage out of the camera so far to me in with my very limited testing is incredible, I didn't think Panasonic had it in them. The colors are perfect to my eyes, the codecs are super easy to play back in VLC and actually easier to edit in Davinci Resolve than the GH5's footage. Both 4K60FPS and 4K30FPS play smoothly even after color grading. So far the footage grades as easily as the R6 footage with the added benefits of not needing proxies. Codecs - You get to pick H.264 or H.265 and still get to shoot in VLOG and 4:2:2 10bit. For some crazy reason Canon with the R6 forces you to shoot in H.265 if you want to use CLOG. I will happily sacrifice a little storage space to never have to try to edit H.265 again. Manual Focus Features - I hated the focus rings on the Panasonic MFT lenses, they were non linear which made manual focusing nearly impossible. I ended up getting manual Voigtlander lenses instead. Panasonic has fixed that big time; not only can you now pick linear you can even pick how many degrees to go from stop to stop. I think the R6 let me pick linear but not the focus throw. I do miss Canon's 3 little triangles when manually focusing, to me that's still the best MF guide in the industry. On my S5, focus peaking doesn't seem to work; its on but I can't see it so I have to play with that some more. Timelapse Photography - Ok I had to throw this one in there. Maybe other cameras have this, but this is literally the first camera I have ever owned that lets you do a time lapse in body without an intervalometer AND that lets you take more than 99 images. That's always been a pet peeve of mine for most cameras.  Wireless Flash Control - Another pet peeve of mine answered by Panasonic, it can wirelessly control up to 4 flashes without needing an additional transmitter. Of course I'll never use this feature since I already have a complete flash system, but for someone starting out this means even less gear to lug around and to buy. Big Red Recording Box - Who hasn't thought they were recording when they weren't? I turned on the big red box right away (as soon as I found it). This is great, and will definitely help in the future. The R6 of course didn't have this. LVF Button - I didn't understand how important this was until I shot with the R6. It was so annoying in the R6 to have to  pick view finder or back screen display. If you picked view finder you had to go into the view finder and navigate back to the setting to change it back. If you picked auto, the screen kept shutting off on me when the camera got to close to my hand or body. Maybe you could map a custom button but I like leaving all of them at their defaults. For the S5 if you want to turn off the viewfinder sensor just press the LVF button...switch to just the VF press it again, switch to auto press it again. So easy to disable/enable one or the other. Auto mode is terrible, switches off the screen all the time if anything gets near the sensor. Here is my neutral list, either I don't really have an opinion yet either way, or I haven't tested the camera enough to feel good or bad about it.
Photography Capabilities - I'm still kind of neutral on the photography department. All I have is the kit lens and didn't have time to try the photography part. If it comes even close to the R6's photo performance that will be good enough for me.  My Sigma adapter gets here Friday so I will be able to test it with my Canon lenses. Auto Focus - I never used it in the GH5 but this time around it is different because I want to try the photography features as well. In my brief testing, the AF worked fine for photography. It still has the hybrid AF option where you half press the shutter button for the initial focus then can fine tune it using the focus ring so that's good enough for me for video. Menu System - It is improved a bit over the GH5 but still nowhere near as intuitive to me as Canon's menus. I think once I set up my Favorites menu it will be fine, but there's so many features I'm having a hard time finding some of them. I never did learn the GH5's menus, I just created a video Favorites list and that's all I use. My 5DIV is a different story.  
Final Thoughts - This camera makes me wish I was a travel photographer/videographer. It has so many uncompromised features that would be so useful when traveling that you could practically literally bring just this camera, a wireless flash, XLR module, a few lav mics, variable ND filters, a small video light, travel tripod, and shoot just about anything photo or video. I'm already thinking about projects that I want to shoot with this camera vs the R6 where all I could think about was if it would even make it through the shoot.
