    Buying a dedicated keyboard or overlay relevant to your NLE is also a great upgrade. Just studying the keys can lead to exploration you might not normally do, and find a quick solution to a nagging problem easily solved by the push of a button or two.

    The newest version of Resolve (that I haven't upgraded to yet) has a visual keyboard shortcut configuring tool that might be useful for that.

    None of us probably actually know him, we likely do not know his intents. He created a toxic environment and derailed threads from my perspective, but I bet he has helped some people at some point lol. 

    When I was seriously considering the A7III and GH5 and trying to understand the lens options etc, I PM'd with @jonpais about his experiences and he was really helpful and wrote me quite a few long and informative messages.  This despite he and I seriously butting heads a few times in the general forum.  I don't claim to know him, but I can see that he has a lot to offer - unfortunately other factors got in the way.

  3. Remember that you can always buy more drive space if a project ends up being larger than expected.  

    Worth noting is that RAW comes in different flavours and I suspect there is very little difference between them in the real world.  People talk about Prores HQ being good enough for most projects, and considering the difference between 272MB/s and 117MB/s you might end up shooting RAW 3:1 or 4:1.

    You're looking at some serious drive space though - 4K RAW 3:1 at 30:1 shooting ratio for a 90 minute film is still 20TB.  That's just the source media - you will also need to render proxies to edit with, and various other assets.

  4. I spoke to my dad and it turns out he has Minolta 135mm and 250mm fixed primes, which he'll be putting in the post and sending to me.  Win!!

    He can't remember which versions, but he said that at the time they were better than the most common ones that people had.  I asked about how good they were optically and his answer was very interesting, he said that he couldn't really tell me because he only ever used them to take photos of things very far away, and at those distances atmospheric disturbances were the biggest challenge, not lens sharpness or film grain.

    Anyway, we'll see when they arrive.

    I'm managing my expectations though.  I suspect that lenses were made to be good enough for the resolution of the best film stocks and probably no more.  If we take a FF lens and then crop into it 2x for the MFT mode, and 1.4x more for the ETC mode, and if that is 4K video which is 8.3MP, that means I'm viewing the lens with the equivalent scrutiny of 65MP.  There is hot debate around what the resolution of film is, but most estimates are below that figure, so I'm anticipating that they will probably be a little soft!  Of course, I'm only using the middle of the lens, which is where it is the best, but 65MP might still be a stretch.. ???

    Hi kye,

    I appreciate the detailed reply!

    I think my biggest problem with Resolve workflow, is that I don't have the proper time to truly learn and use it.

    My personal time is limited due to a high pressure fulltime+ job, sigh...

    I only get to use Resolve sporadically, and often forget what I did during the last session.

    I sympathise.  More than once have I decided to solve a problem, done the research, and found the thread on the BM forums where I asked the exact question a few months prior.  Or found the answer, gone into Resolve to map the function to a hotkey and discovered I'd already done it!

    I've said before that learning Resolve is like learning to fly to space shuttle.  Probably a good idea would be to make a set of notes for yourself, perhaps organised by each page, of hotkeys / menu functions / etc that you use, then next time referring and adding to it.  I say this as advice as much for myself as for anyone else.. lol ???

  6. Most camera tests are more influenced by how accurate the focusing of the lenses is, or how similar the shots are (true A/B comparisons require you to point the cameras at the exact same thing under the exact same lighting - something most reviewers don't understand!).

    You want to do normal tests and also stress-tests.  Trees blowing in the wind is a good stress-test.  I designed a torture test by making a 4K video file with 3 frames of completely different photographs, exporting it as Prores and playing it on repeat, then setting the camera to a very short shutter-speed and framing up the monitor.  Codecs normally do well when frames are similar to the previous ones, but do badly when frames are very different.  This test absolutely destroys some cameras and others hold up very nicely.  It's a total exaggeration but gives useful information if you don't have a tree handy.  It's also 100% repeatable between cameras so is a valid test.

    My advice is to test things properly, make your decisions, then move on to making real content :)

    Fuji has pretty nice colors without grading, its actually the reason I switched over from Panasonic. But yeah it probably is a good way to go, though no 60p. 

     

    Built in ND's would be nice. I can't really say anything about C100 auto focus as I've never used it. Yeah I forgot the C100 is actually pretty small. I'd not go for an FS5 as I am color blind and need either a Canon or Fuji to rely on lol. I might pick one up if I find a really good deal on it. I need three cameras for shooting, a used C100 might a good option third camera. Continuous recording is nice. 

    We spend a lot of time here talking about different systems, but remember to take into account the practicalities of actually owning multiple systems.

    Fuji and Canon both have nice colours, but they don't have the same colours, so there would be work in post to match them, especially in scenes like the wedding ceremony where I imagine you've got a multi-camera setup and are cutting between them frequently in the final edit.

    There's also the advantages of having compatible lenses, media, etc.  Unless you knew that you were always going to use the C100 with the wide, and the Fuji always with the long lens, but I suspect that's not the case.

  8. @KnightsFan is right, but to re-emphasise, this isn't a hardware problem.

    When you're rendering video, it doesn't need to happen in real-time.  I frequently export projects at anything down to 1 frame-per-second, and the HDD, CPU, GPU, etc all just chug along at whatever speeds they can manage and eventually the export is complete.  YouTubers often talk about rendering out their 10-minute videos taking an hour.

    Thank you Shirozina. To your point on banding, I had also done a quick test at one point with ProRes HQ and found it to be near identical to the original. Small differences started creeping in with ProRes and moreso ProRes LT. Didn't think to checking banding. Never made it to 4444 territory... seems it seems crazy to have to hike it up like this to hang onto those subtle gradations. Are there other codecs that can do things better?
    My limited understanding on transcoding from a highly compressed (mpeg2, h.264, avchd, etc) 8bit file to a larger 10 bit (ProRes) file sort of had me thinking that most, if not all, of the original file info would be retained within the confines of that more robust codec... and so there would be even less chance of banding. Lossy, I guess not.

    Somewhere way out there in all this, I still try to remember that this stuff is somehow connected to story and storytelling ;) Thanks again folks.

    People tend to transcode to Prores HQ or DNxHD HQX files as proxy media, often depending on what platform they're on (PCs can't make Prores files IIRC), but my research didn't turn up any differences in quality between the two formats, so use whichever you like.

    If you want way too much information about proxy formats, here you go....

    The second link shows the bitrates of the various codecs and you'll see that Prores HQ and DNxHD HQX are very similar, but note that DNxHD HQ is 8-bit vs DNxHD HQX is 10-bit, and this will likely make a difference so is worth checking if you go the DNxHD route.

    With all things, when you make a compressed copy of something you only degrade the quality.  However with high quality codecs like these the degradation will be minimal and likely not a factor in the end result.  As you say, this is about story and storytelling, and I think that the ability to edit with smooth playback will add more to the storytelling than the very slight degradation of the image will detract from it.

    Is there anything inherently wrong with generating/saving a new DB per project?

    Not that I know of.  IIRC Resolve has some built-in tools for backing up databases and otherwise managing them, but creating one per project seems like a neat and tidy kind of approach.  I'd suggest a bit of googling to just check it's not got some unknown issues - Resolve can be a bit like that sometimes.

    11 hours ago, buggz said:

    I was thinking of copying the data from the camera to the internal stripped SSD drives, and creating all the project directories using these drive paths.

    This way, I only have to copy the backed up project data back to the SSds and not get the dreaded media offline errors.

    Wanting to use the fastest drives, while not getting the media offline errors when the project isn't on the current external drive.

    This process makes sense.  Copying the whole card/cards to the SSD array, editing it there (likely with directories for music, SFX, exports and other project files), and then backing up that whole directory structure to your archive drives when you're done seems good.

    If you want to revisit the project once it's been moved from SSD array is actually not that hard, as Resolve has a great function for relinking source media.  If you go to the media pool, highlight all of your offline clips, right-click and choose the option Re-link Source Media (or similar) it will ask you which directory to look in.  If you point it to your source project directory it can look through the whole directory structure and find all the files.  I use this function all the time and it works really well.  If you just needed to render out a new export, or make a couple of small changes to the grade or whatever then you may find that working off the slow archive drives is quite functional.

    One thing I'm not clear on (and am still working out for myself) is the pros and cons of archiving completed projects.  My current approach has been to delete the optimised media and render cache files (via the Playback? menu in Resolve) and then renaming the project "ARCHIVED <project name>" in the database so I know I've deleted them.  Otherwise you gradually fill your SSDs with cache files (stored in a non-human-readable directory structure), like I did.  This means I have a database with all my past projects in it and can revisit them whenever I want to, re-linking to the source media as I described above.

    However, Resolves project archiving feature might be better for you.  It appears that it copies/moves (?) the whole project, all the source media, optimised media and render cache files to a drive.  From reading the section "Archiving and Restoring Projects" on or around page 76 of the Resolve Manual it seems like the directory structure is non-human-readable and to re-access the project you'd have to restore the project, probably copying/moving all the media once again, which is a large overhead.
    If that's true it would also be a PITA if you wanted to look at the source media from that project (eg, if you were making a showreel) or quickly re-export with slightly different settings. 

    I shoot home and travel videos of my family, so I copy all my footage to a directory structure based on a /YEAR/YYYY-MM-DD <event or location>/ naming convention, which contains all the video and photos I take with any of my cameras, and I often want to include footage in multiple projects, for example a trip video, a year-in-review video, etc.  So having my footage all locked away by Resolve in archives wouldn't suit how I work.

    I've re-written this post a few times as I fact-checked and learned more during writing it so hopefully that makes sense! ???

    Interesting different (reverse) acquisition approach :)

     

     

    So many good cameras out there..  When I watched the GH5s vs P4K video I was more impacted by the slight changes in focus between the two cameras instead of the cameras themselves, which is in the skill department not the equipment department.  

    I remember someone (@kidzrevil perhaps?) speaking about the Resolve Super Scale feature and how great it is, so that's something that might breathe new life into lower-resolution footage.  More info: https://www.premiumbeat.com/blog/resolve-15-super-scale-feature/

    In terms of using slow-motion, I would suggest it's a new genre of film-making.  Like all genres it will have fans and critics.  Personally, I agree with @mercer around testing a camera by actually making a short film.  That way, not only do you test the equipment by using it how you would on a real project, but you also get a real short film at the end of it, which is what all this fussing with cameras is ultimately for, right? ?

    Yeah as i expected haha. Also if you talking about american football - field is only 10 yards longer. 

    Australian Rules Football..  Wikipedia says that fields are "typically 135–185 metres long goal-to-goal and 110–155 metres wide" but I don't think he's on the full-sized field just yet.  It's amusing that there isn't a standard size too - hooray for being Australian and basically not giving a sh*t about anything! ???

    You want a better lens than the 55-250 but for the 1\3 of its price?

    There is a problematic in your logic!

    I like the Canon nano lenses, believe they are some of the greatest deals in photography, ever. The 70-300 is really good and really cheap for what it is. 

    The new 70-200 4f is great also, but another league (especially moneywise).

    I'm seeing lenses like the Nikkor AI-S 100-300 f5.6, Tamron 80-250 f3.8-4.5, Canon FD 75-200 f4.5, Vivitar 75-205mm f3.8, etc that I can get for under $100 including shipping.  

    The problem is that I don't know which are good and which are lemons, and considering that I can basically adapt any lens mount, I have a huge number of lenses to choose from.  Today all lenses are optically excellent, but back in the day they weren't, so you can end up with something with nasty CA, isn't sharp (which matters as I'm seriously zooming in to its FOV).

  13. I just looked up how big a lacrosse field is, and our football fields here are quite a bit larger, so that would factor in too.

    if you need more overall reach, like more than a 100 400 or 70 300mm equiv. Your best bet is to go with tele primes. 

    Hang on, a 200mm lens is enough, because with the 1.4x crop of the ETC mode and the 2x crop of MFT sensor size, a 200mm lens will have the same FOV as a 560mm lens on a FF camera.

    There are a bunch of lenses in the 70-200mm or 100-300mm range that look good.

    I shoot sports Pro all the way down to youth Lacrosse. 600 is going to be way to long and a total pain to pull focus at, even if you stop down to F8. 

    When I was shooting with my Canon 700D and 55-250mm lens I used it in the Magic Lantern crop mode which turned it into a 264-1200mm equivalent lens.  The 1200mm took waist-up portrait shots from the other side of the field and I got a few really nice shots like that, so that was the most zoom I would want.  With a 600mm equivalent lens I'll be able to get 1200mm in 1080 by cropping into the 4K from the GH5.

    The 55-250 was a total pain to pull focus with because it is a cheap plastic lens and had a bit of play in the focus ring which made small smooth adjustments very difficult.  Any half-decent manual lens should be 1000% nicer to use in that regard.

  15. I want a lens to shoot my kids sports games.  I will be using it with the GH5, which has IBIS, ETC crop mode, and (paired with a non-speedboosting adapter) the MFT 2x crop factor.  I'm therefore thinking a fully-manual vintage lens could fit the bill.

    From shooting previously I've found that 600mm equivalent is enough reach, so if that's with the ETC mode, then the lens only has to be up to 200mm.  A zoom would be really handy.  My preferences are for a lens that has good IQ, is nice to use, has MF the right way, and has a longer zoom range.  I can probably extend into the $100-200 range if there's something really nice, but cheaper is better :)

    What lenses should I be looking at?

    A7S II + canon FD 35mm 40$ lens. No IBIS, no AF, with Sony colors that people can't live with, no 4K. 

    Cool video.

    I know that 4K / colour science / AF / etc are not required for film-making, and I know that you also know that.  

    It kinda makes me question though... I thought that most people here know that too.  Do you think that there are lots of people on this board that don't understand these things?  We all get excited by the tech, but when it comes to the art I thought we all calmed down a bit and regained perspective.

    It is not the same. They are talking R, G, B stuff. It is still pretty impressive looking though one though either way, especially at night..

    Cool.  So, 3680 dots <is about> 1.2MP <is about> 1240x990 resolution (assuming a 5:4 aspect ratio).  I just wondered because the viewfinders in the video I posted were 720p and 1080p and I wondered how the GH5 compared.  He said that there was a slight difference between 720 and 1080, but that 720 was ample.

    I must say that the viewfinder is very nice, especially when you put on fast and high quality glass :)

    Why are you transcoding? You will loose image quality for a start and Resolve has various methods like Proxies, Optimised media and render cache to enable you to work with easier codecs in the timeline and then render the final result from the original source footage so you don't loose quality.

    Great question..   I assumed @User was just using Resolve to generate media for use in some other software, but maybe that's not true?

    Thanks again for your valuable insights @kye - I've went ahead and ordered the GX85- newegg had it with the 12-32 lens for around $400 which is not a LOT of money in case it doesn't work out and I could probably sell it for a little less.

    I have fairly steady hands and with a back that goes around the neck, I'm hoping I could capture just using my hands. I've also ordered the Yelangu L4 that @BTM_Pix has posted. If it has steady wheels, I should be able to get some good rotating and slide shots. All of the gear should (hopefully) arrive in two weeks!

    Cool!  Let us know how you go when you've had a chance to test it all :)

    You can always just use a $20 adapter. 

    True, but only for longer focal lengths.  

    If you're looking for a lens in the 100mm+ equivalent range then 50mm f1.8 lenses are great and cheap, and longer and slightly slower lenses are (almost literally) a dime a dozen.
    If you're looking for lenses in the range of, say, 50-100mm equivalent then you can get things like 28mm or 35mm FF lenses, but they're either cheap and slow or expensive and fast.
    If you're looking for lenses around 35mm equivalent then there are lots of 18mm APSC lenses around but you have the same cheap and slow or expensive and fast problem.
    And if you're looking for lenses under 35mm equivalent then you're basically screwed with a 2X crop on adapted lenses as 8mm or 14mm lenses are more expensive, and if you want 8mm and non-fisheye then it's time to sell a kidney!

    Pairing the Pocket 4K with some good vintage glass is pretty blissful. There's been a lot of talk about how it looks more digital and modern than the previous BMD cameras - and yeah sure, I guess it's not as organic and grainy as the 2,5K. But throw on some c-mount glass or a speedbooster and old Pentax stuff and the camera sings. Haven't used it with this kind of setup on a production yet, (it's playing second fiddle to the Ursa Mini and been on a gimbal on about half a dozen shoots now) but I'm just having a lot of fun taking it on a walk and just taking some throwaway nature shots. It's something I used to do back when I used the 5DMK2 regularly, and I'm happy it has revitalized that habit again.

    pocket_1_72.1.thumb.jpg.0437de0e01a20850a7f3530bb23e2189.jpg

    This was taken with the speedbooster and a Pentax 35/2.3 M42 lens on a cool winter afternoon. One of my favourites due to the very distinctive, oil painting-kinda way it renders out of focus areas and the transition between them and in-focus areas.

    Nice looking image.  I'm doing the same thing with my GH5 and adapting lenses - using the GH5 10-bit mode to get the colour depth (not quite like RAW, but better than 8-bit) and the lenses to render the scene in a non-clinical way.  I've got a couple of Helios lenses, and I have both SB and non-SB adapters for it.

    One thing to note is that modern lenses can be used as "semi-vintage" lenses too, if you use them wide-open or completely stopped-down, as this will normally soften the image significantly and is one of the things that people like about some vintage lenses.  You can also 'cheat' a bit with them and use a bokeh modifier on the front of the lens to change the shape of the bokeh from the normal shape to something a bit more interesting.  I suspect that if you have a 3D rather than 2D bokeh modifier then you can get different shaped bokeh in different parts of the frame, the way vintage lenses do, but I'll have to test this.  It depends on what you're interested in.
