Yeah they really are special cameras. Every time I read too much discussion about 4K this or 4K that, I go back to my Vimeo favorites and watch some videos from the Pocket, the Micro or some ML Raw.

I wouldn't be too down on 4K...  Think about it like this - we like things like high DR, higher-bit-depths, higher resolutions, lack of over sharpening, etc.  If you think about it, except for DR, all of those are related to compression.  Bit-depth is colour value quantisation and resolution is about image detail quantisation (over sharpening creates artefacts similar to JPG compression and is related to the distortion of high-frequency image information) but all of these are related to throwing away information.  Assuming the camera manufacturers allocate the bitrate in a sensible way, which they are pretty good at doing (ie, not 480p with 30-bit colour depth or 8K with 3-bit colour depth), then image quality will be roughly proportional to bitrate.

If we look at a few random cameras, this plays out:
My Canon 700D natively outputs <50Mbit 1080, but ML can do ~300Mbit.
The Canon 5DIII natively outputs <50Mbit 1080, but ML is something like 500Mbit? (I'm not sure on this but it's a lot)
My Canon XC10 records 1080p25 in 35Mbit, 1080p50 in 50Mbit (which is 25Mbps when conformed to 25p) and 305Mbit in 4k25
IIRC the GH5 records 1080 in 100Mbps and 4k60 in 400Mbps (166Mbps when conformed to 25p)

The BMPCC records 1080 at 230Mbps in Prores and 569Mbit in RAW.

When you look at IQ like this it makes sense about why the BMPCC and other models in the range still stack up.  It also makes sense why people are drawn to 4K recording modes, and why despite lacking 4K TVs have looked fine for decades.  I don't know what the signal-noise ratios of analog television was, but the combination of a good signal, high DR TV and a darkened room would have represented a high bitrate, as would film.

With a few exceptions, 4K is the only way to get high bitrates out of the 'stars' of the DSLR revolution.

The size is right, and given the wide angle it is possible to shoot blind. But, does this model record 10bit 4K via HDMI? Unfortunately not, just 1080. We need an upgraded model.

I completely agree.  A new model that did 10bit 4K (and maybe a 'premium' model that does 10bit 4k60) would be excellent.

However, it's worth considering that the RX0 isn't as much of a shooting-blind-action-camera as others because of it's 25mm equivalent lens, as compared to the GoPro at around 14-17mm. For the RX0 the rig where it's mounted to the top of the monitor makes more sense.

Considering that the RX0 isn't fixed focus, how much of a challenge is it in getting focus?  I'd imagine it's got a relatively deep depth of field.

Now we have another reason to want a small external recorder

Some time ago I was looking at external recorders and learned about the Atomos Ninja Star - something that I assumed would be a spectacularly useful and popular product.  Then I discovered it was discontinued and was stunned.

If you were using the RX0 as an action camera (ie, mounted and used 'blind' - unlike most of the examples here which treat it as a normal camera) then the Ninja Star would be the perfect companion.

Maybe Atomos is the Canon of external recorders and protecting the higher models in their range..

What kind of setup would people use this in?  I thought that by the time you add an external recorder (and likely a cage of some kind to connect the camera and recorder) that the benefit of having an action camera was lost and you may as well have a larger camera.

Not criticising - I'm interested to hear how it would be used

Why don’t we try to do a “festival” here on eoshd? Someone suggest a theme and give everyone a week or whatever. We link our offerings, sit back and enjoy... we’d have to agree to do the beer/weed thing remotely.

Big question - how many would participate?

Liam - organise it!!!

I'm in!

Maybe it could be weekly or fortnightly (just don't submit if you are busy during that time) and maybe have an optional challenge, like "something red" or "up high" or "complicated".

I find that the optional challenge might be inspirational.

Is this film festival a way to find film friends then?  if so, maybe social media might be a good place to reach out to people.

Especially if there's a film festival already in your area and you want to be a bit counter-culture about it, you could post on a bunch of forums or whatever saying something like:

If I were you I'd just call up the buddies and have a night of it. 

Completely agree.  

Perhaps calling it a "short film night" might have better connotations?

How often do you finish a project and 'publish' it by sharing it (either with the end audience or, if you do one step in a larger production, with the people who do the next step)?

Do you want to finish projects more frequently?  Less frequently?

What are you doing to accomplish this?

I'm interested in hearing about other people's workflows, efforts to increase efficiency, and barriers people face.

Personally, I make home videos and 'publish' to family and friends.  I don't publish as often as I should and recently I've just gone through a phase of reviewing my equipment in preparation for a couple of big trips I've got this year, so the production line of editing (and getting through the large volume of footage I've got) has stalled in preference for technical evaluations of lenses, camera settings, etc.  I'm almost coming up for air, but I've made a few key improvements to get a good workflow setup, something I wasn't completely clear on previously, so I feel it's been worthwhile.

I heard a story (no idea if it's true) about someone in the industry - maybe they were a film critic(?) - that had a large shed in their backyard that was setup as a makeshift cinema and they ran a video night every Friday night.  In summer they had it outside on their lawn.  Anyone was welcome to attend, they showed short films on any format (I think he had a collection of players for different formats, like VHS, Beta, etc).  It was famous for being a completely mixed bag - great films mixed with awful crap.  I heard that often the best ones were shot on poor quality equipment as his night was known to accept all formats so it attracted those people that either didn't know how to get access to good equipment or didn't know it mattered to film-festivals until after they'd finished.  Apparently he screened a film shot on one of those Barbie cameras (where the camera was mounted in the doll) and it was well received by the audience despite being very poor image quality.

So I kind of want to start the smallest film festival ever…

In contrast to the other helpful and valid posts above, I'd like to challenge you a little bit around making it smaller rather than larger.

If I record a clip on my phone and then show my fiancé then is that the "smallest" film festival?  I would imagine that you would probably say that's not a film festival, and I'd probably agree with you, but what is important is WHY isn't that a film festival?  What are the minimum elements of a film festival that make it a film festival?

If I invite some mates over and we watch a video I shot, is that a film festival?  If not, what's missing?  More people?  More films?  Films must be edited?  Must be advertised?  Must be judging and a winner?

Make a list of what you think you require.

What are you hoping to get from hosting it?  Fame?  Fortune?  Gratification?  Gratification of what?  Making community?  Making a lot of noise?  Making a mess?

When you've done that, try and figure out how to minimise it - if you don't need a huge audience then you might not need a venue, which might mean you don't need insurance.  Try and think outside the box on this.  Ask yourself what you're willing to do in terms of 'breaking the rules'.  For instance if you were only interested in the community aspects of it you might drag out a an old Ebay projector (good films look fine in SD) into a park and use your mates car for sound, you'd probably be in violation of some kind of county laws or whatever, but maybe you don't care about these things.  Maybe there's a park that no-one will notice you using if you get there later in the evening (in summer it gets darker later so that works too).  Word of mouth and maybe photocopy a few fliers would get you enough audience for your own purposes.  

I think it's an awesome idea and I wish you all the success in the world, but I challenge you to think about what is important to you and have the smallest simplest cheapest least-official event that meets your expectations.

Many you"tubers" have this problem, ten minutes of "talking head"to say something that could have been summirized in 60 seconds.

Yeah, and you know what 'streaming' is and why it's becoming so popular right?  It's making videos without the editing.  Or, as I like to call it, "you save 4 hours editing and 100,000 people waste 30 minutes watching crap you should have edited out - creating a total waste of 50,000 hours minus the 4 you saved yourself".  Or shorter - "selfish and worse".

Of course, some you tubers had already worked out that not editing anything saved them time before streaming became a thing.

In case any YouTubers are reading this, please drink deeply from the following statement...   IF YOU DON'T HAVE A PRE-WRITTEN SHOW WITH MULTIPLE PRESENTERS AND AT LEAST ONE PERSON PRODUCING THEN YOU ARE WASTING THOUSANDS OF HOURS (OR MORE) OF HUMANITIES TIME.  IF YOU'RE NOT A PRO AND CAN'T DEVOTE THAT KIND OF TIME THEN DON'T STREAM, AND IF YOU ARE A PRO AND YOU'RE NOT DOING THIS THEN DO YOUR F**KING JOB AND KEEP IT INTERESTING FOR THE WHOLE F**KING SHOW.

I know I don't have to watch, and I'm optimistic that eventually everyone else will work this out, but in the meantime the person whose time you wasted might have done something that helped cured cancer instead of watching you read the comments section without saying anything useful.

Ok, rant over.

Another quick little clip using 60 and 120p footage and Eterna (graded in Resolve).

Nice footage.

If you get a chance it would be interesting to see the quality if you exported and uploaded this in 4K/UHD to YouTube.  I've done tests and found that YT compression is far less brutal on 4K.

I see lots of compression artefacts but it's hard to know what is the camera and what is YT.

If you don't have time then no worries - thanks for sharing!

Interesting thread, and a topic I've come at from a different perspective.

I bought my XC10 partly as a stills camera.  I'm sure that will come as a surprise to many, however for my needs it does make sense.

Firstly, I'm a rubbish photographer in terms of 'the decisive moment' and even sports photographers don't rely on hitting the shutter at just the right moment.  In this sense video is constant 25 FPS burst mode, so I should be able to pick the perfect frame in post.  Even sports cameras don't offer anything much more than 25fps burst modes.  One of the camera manufacturers (is it Red?) has a page on their website for magazine cover images taken from video.  I remember watching a video of headshot photographer Peter Hurley trying uncompressed 4K instead of still images, and he said there were too many frames to go through, so video is the 'ultimate' burst mode in a way.

Secondly, if a singular moment of fun is about to happen (it's my kids birthday and they haven't seen the cool cake yet, someone is receiving an award, etc) do you video it, or take still images?

Thirdly, building on point #1, the quality has to be sufficient.  Taking a stills frame from an ageing Canon DSLR will likely not be sufficient.  Therefore I wanted a 4K camera with a high-bitrate, which the XC10 fit the bill for.  In preparation for this I posed a few key questions to myself:
Q: What is the most demanding use I will have for still images?  A: printing at 8x10.  I'm not likely to print larger than this, and online won't go larger than this for a long while.  There's an argument that no-one needs more than 5MP because the larger you print something the further back you stand from it when looking at it.  That might not be 100% true, but it's worth taking into consideration.
Q: What is the most demanding user I will be putting these in front of?  A: these are photos of family and friends, so no-one who will be super-picky, and no paying clients.
Q: What is the minimum level of quality that I will require (in line of above)?  A: I did tests - 1080 frames were captured as still images from a point-and-shoot video, processed in LR, then displayed on the computer screen at varying sizes.  I found that 2MP isn't quite enough, that the codec was quite fragile and anything other than slight brightness/contrast/sat adjustments 'broke' it - this is worse in low-light.  This created my requirement for a 4K, higher bitrate codec, high DR camera with decent high ISO performance.

One compromise in the above was that shooting for stills requires a shorter exposure time than the 180-degree-shutter-rule, but that's life.

My tests from the XC10 were that still images taken from the 4K and then re-compressed were at a level of quality equivalent to about JPG quality 11 out of photoshop.  This is the equivalent image quality of higher-end compact point-and-shoot cameras with full manual controls that lack RAW capture and only support JPG image formats.  Obviously RAW would be better (!), but if you think of this as being an infinite 25fps burst mode of 12MP quality level 11 JPG images, that's a pretty decent level of performance and would suit many non-critical applications.

I only have personal experience with the XC10, however the above logic should apply to all current high-bitrate, high DR, 4K cameras, and those with 10-bit instead of 8-bit will of course be higher quality again than what I have from my setup.

I guess the question to ask is - how good is good enough?

Many other smartphone companies are also developing multiple focal lengths like 25mm, 50mm, 80mm packaging in one unit

I'm really looking forward to that.  I remember reading somewhere the estimated cost to Apple for the camera assembly in an iPhone and thought "Shit - I'd gladly pay for 4 of these if you could work out how to output a better image because of it".  Different focal ranges is the obvious step, and would make a phone so much more useful.

I went to go see one of my kids in the school play last night.  I wasn't sure on their policy on taking cameras as they widely publicised they were making their own video of the production.  They had signs up that said that we were allowed to take photos / video of our own kids, but no-one was allowed to publicly upload video containing any other kid without written permission of that kids parents.  I understand that totally.  This is the kind of shooting environment that phones find their way into, and having a wide lens really doesn't help with this at all.

I took high-bitrate 4K footage and will crop in post, but if my phone had 24, 50, and 100mm lenses to choose from then it would be far more suitable for things like this.

What's the small thing on top of the main camera?  Is it a remote viewfinder?  Or a small digital camera being used in parallel for footage review and management?

Canon 70-200mm f2.8 II and I think the 24-70mm f2.8.  Definitely the 70-200 on the closeups.  The first 3 shot were mirror reflection shots.  If they could stabilize the live view the 5D3 would be a beast.

Considering what you'd have to pay to get equivalent image quality, maybe there's budget for a gimbal in there?

In addition to the above, it's worth noting that the larger the wheel diameter the better they deal with any loose objects they have to run over.  ie, a bike can easily ride over a power cable but a skateboard would have issues.

You haven't specified where you'd use it, but it's something to consider if it's going to be used on surfaces that aren't perfectly smooth.

I'm assuming you're referencing my post as I was the one that was talking about AI..

it seems there was a mis-understanding.  I wasn't saying to rely on AI to somehow future-proof my footage.  I was saying the opposite - I was saying that although AI will do fascinating things, in the not-too-distant future things will have changed so much, and from there looking back our 4K will be potato vision.  It will be unusable except for nostalgia.

and to directly answer the OPs questions:

I'm wondering, with the current crop of reasonably affordable 4k cameras today, if the difference between cameras will be less noticeable in 10 years?

Yes.  They will look back and see no difference.  To them both will look like complete unusable mindblowingly bad poop, or it will be cute and retro and trendy and have no seriousness about the IQ applied at all.

How much do you look at Charlie Chaplin films and distinguish between the ones before he could buy a sharper lens and those before?  Do you care?  Could you even tell if you wanted to?

If you want to future-proof your films, make them good enough that people in 10-years will still watch them even though the quality was bad.  Charlie Chaplin isn't still a famous name because of the image quality of his films!

Have we more or less arrived to a place where digital image quality is will hold up the way motion picture film did? 4k seems adequate enough, and we have that. Dynamic range will probably see incremental bumps, but how much further can that go?

We can go further than anyone in this forum can possibly imagine.  

IIRC we've created sensors that can detect individual photons of light, so once they're miniaturised sufficiently we'll have sensors that have the bit-depth of the universe and billions and billions of pixels.  The Apple A11 cpu inside my iPhone has 4.3 billion (BILLION!) transistors in it, and is probably smaller than full-frame.  If those transistors were photo sites (a reasonable comparison as it's a simple circuit that requires power, data in and data out connections), that would be about 90,000 pixels wide by 50,000 pixels high.  Just for fun I'm assuming the future is still 16:9.

@jpfilmz that is absolutely stunning.  reminds me of the likes of things like ARRI promo videos etc..

Ain't that the truth. And towards this, and the idea of using (documentary) material captured on older/ lesser cameras to be combined with new cameras in the future, part of me wonders, if in ten years, there will be software that will be able to bite in these 'thin' codecs and 'fatten' them up. Now I know you can't exactly pull something out of an image that isn't there, but it feels like this is, somehow, about to change.

You can't pull something out of an image that isn't there, but you sure can have a good look at what is there and take a guess about what is missing.  Humans do this kind of interpolation all the time... there's a loud noise and we miss a few words in a sentence but we can guess by the context what they were, it's raining really hard and the windscreen wipers on your car aren't keeping up so half the time the view of the road is blurry and the other half it's got big drops all over it but not only can we keep the moments when we could see properly in our heads when the rain obscures everything but we can somehow correlate what we saw clearly with what is now blurred and if something moves suddenly during the blurry part our brain has kept track of what it was and even what it might look like if we could see.

This is how computers will do it.  The first phase is being able to recognise objects (which Google etc now do pretty well from photographs), the net phase will be to be able to understand an image in multiple layers and for them to have an understanding that the part of the person that is behind a pole still exists but is obscured, and the third will be to have a huge database of objects and be able to stretch and manipulate them in 4D space with all the physics applied and then match them to what it's seeing and put in the detail that isn't in the image.

If you and I see a blurry image of a person wearing a scarf we know that the scarf is probably knitted (coarse pattern of woven thread) that has an array of fine textured fur around that coarse structure.  AI will soon know this and substitute it in for us.

What's the point of having my movies future proofed if they suck and I'm forgotten tomorrow? 

Absolutely!!

Historically we will plateau when IQ becomes close to the limits of our perception, HOWEVER we are nowhere near these limits yet.

Think 4k is enough because movie theatres were fine in 2K?  What about VR capture - if your field of view is 120 degrees (just to pick a nice number) then that means you need 6k to spread  2K over your entire vision, but that's not what we're talking about here - we're talking about the angle of view of a TV - which is something more like 45degrees, which means you need 8 * 2K horizontal, just to properly render sitting in a room watching a 2K TV.  What about VR simulation of a 4K TV?  Forgetaboutit!!

But why just talk about resolution - let's talk about pixel depth..  what is the DR of the human eye?  When they get "retina DR" devices, what will the bit depth of that video signal look like across that amount of dynamic range?  I'm thinking that 10-bit isn't going to cut it at that point.

And we're only talking 2D here....  what happens when we want 3D environments to be simulated from AI processed video feeds?  Just mount a grid of cameras in the ceiling perhaps 12 inches apart and feed all those to an AI that creates a 3D VR environment and UH OH!  The AI doesn't have enough information to go by and so the virtual attendees of the latest Hollywood whatever event can't see the expressions on the stars faces (or tell the difference between Elijah Wood and Daniel Radcliffe!) so we need to up the resolution.  Now deaf people can't lip read, up it again.

Now the FBI gets interested and decides that the tech is now ready for AI facial microexpression monitoring at all airports and other critical locations - more resolution needed!

To many of you this will sound like science fiction, but you will be proven wrong.  if you want evidence of this - pick up your smartphone and start talking to your virtual assistant, and then cast your mind back 35 years when many people still had Black and White Television.

@webrunner5 - thanks!  I just chalk it up to having a good memory and reading / watching too many tutorials..  We are all standing on the shoulders of giants.  Everything from Montage Theory to the psychology of colour to the basics of composition from the early days of photography - we're swimming in images that have absorbed many many decades of talent and hard work.

Kraig Adams (who did the above videos) is a bit of a wolf in sheeps clothing in film-making terms.  IIRC he started  filming weddings straight out of school, got crazy good at it, then created the Wedding Film School YT channel (which is excellent BTW), before pursuing vlogging and other videos and phasing out wedding filming altogether.  He's also a minimalist so is a deep thinker in terms of what he needs for the final film and then how to get it with the minimum of equipment.  

I watch YT film-makers / vloggers a lot, but they're all operating at close to this level, which I know is the exception rather than the rule.  Several of my favourites have things like C300s in their home studios for their talking-to-camera pieces, or at the least use A7SII (as Kraig does - including the above) or equivalent performance cameras, so they're at the top end of the platform.

As someone who is also on the 'downhill' side of 40, they all look young to me too!  
If you're interested in more outrageously talented Yuotubers I can happily recommend people like: Brandon Li, Leftcoast, Peter McKinnon, and for people that are all about content and not film-making talk: Primitive Technology (videos of him making stuff in the bush without tools - he does not speak), and Andrew Huang (behind-the-scenes of making electronic music but I think his videos are better than the music).
