Excellent breakdown. Thank you! Logically, then, the compression requires some amount of cpu power. So I suspect "Uncompressed 10-bit" is the default because it keeps Resolve snappy (at the cost of disk space).
I leave my render cache set to uncompressed because when outputting, I have DR set to use render cache for output which can offer a significantly faster output instead of having to rerender everything on output. I do have a large M.2 cache drive.
Should be noted that if you are a person that still uses Optimized media, ( by right clicking the media and telling Resolve to create it), that Resolve creates that media in the render cache folder - and it uses database friendly ( but extremely not user friendly ) file names - using numbers. Although I believe that Resolve is phasing out Optimized media, It takes up massive amounts of physical space on a storage drive where the render cache is stored. To which if you fill up - you will suddenly get the dreaded "media offline" screens on your timeline. Also Patrick, I think you can verify your conclusions about the codec by looking at the render cache size, but it needs to be controlled where you delete all cache - set the codec - then turn on the render cache to User and select the same clip ( or clips ) on the timeline and force a render. Because just checking the render without those steps - the size can be related to the size of what is rendered. So it has to be the same for each version to check later. Also other things when updating to a new version resaves, so the first time opening the new version it will take longer to completely load - so first run always seems slower. This has been the case for all updates over the years.
Oh wow i hadn't thought about Optimized Media saving to you that folder! Thanks so much for pointing that out. It does feel like optimized media has sat at an interesting point for a while since they've also to Proxies in there now. My render cache tests were using the same length clip on timelines of the same resolution and I cleared the cache for each individual folders a few times and let it cache to try to verify. But those sort of technical benchmarks are absolutely not my forte so I didn't want to come out too strong with my claims.
If you think it's a bug, a way to check is to open the produced .dvcc files in a (hex) editor. The first few bytes will contain a tag of the codec. For instance dnxhr_sq. This can be used to check if the setting isn't going through appropriately. I.e., it's using something wrong for e.g., dnxhr_lb.
When I use smart render it does everything on the timeline and for a 30+ min video that cache is huge. How do you just use render on one clip and not the others? Or is that not possible?
you have a lot more control over the User cache setting and in that same cache area of the project settings you can turn off auto-caching most things and by right clicking on individual clips you can cache fusion effects or color grades
I cleared mine out earlier this week, a cool 130gb Good call on changing the settings though, going to investigate that made me catch that I've not actually been editing in a 4K timeline for months, just 1080.
Would you do a video on the difference between timeline frame rates and footage frame rates, for example, why somebody doing gaming footage would want a 29fps timeline using 60 fps footage? thanks!
Nice vid Patrick. Question: What do we do if we have the hard drive space and we want HIGH QUALITY render caches. I've got a 4k timeline and my renders are 1080 at best. Extra crappy if the image is scaled. Help!
It’s a real pity one cannot set a limit on used drive space. Especially as SSD do not like being filled to 100%. Doing so can result in sudden SSD death- or substantive drive slowdown to as little as 30MB/s (I have seen this on Apple internal SSD -not easy to recover from at all! A real problem on a $4000 Mac where an editor has not set an external cache drive. Poorly managed cache files could really ruin a users day in a very expensive fashion. Even if BMD merely set a resolve warning and a system notification that automatically warns users that their cache drive was becoming full, and provided advice and options to manage cache data more effectively. Lots of new NLE users out there could benefit from such warnings, because now that Resolve is popular in the wild outside Post houses with skilled IT support, it is important to consider the needs of lowest common denominators.
This is what happened to my Samsung Evo 970 just now. Yesterday davinci was set to "Smart" render cache and filled my SSD after that i had a lot of issues and had to delete the cache then windows explorer had issues due to that. Now the thing is my SSD is fine but since there is no Limit to the cache size i'm not using it anymore, such a bummer I would just limit it to 100gb or something, It took up 400+GB for a single 10gb video.
Hi I still haven't found the answer of where to setup the project drive on davinci resolve do we leave it with main drive and separate drive for cache if there is no help I will give up and just use photoshop and lightroom due to time consuming it's so complicated
Good info, thanks! But I have a question: sometimes I'm applying some effects for example "Analog TV" and I waiting for cache generation but even though it's still hard to play or this applied effect look like shit. What's the problem here? (BTW, I'm using M3 Max Macbook Pro)
if an effect is fully cached my first guess would be something life hard drive speed if it can't read the files it's read in real time. There's also some instances like when you're using Adjustment clips where the footage underneath it might cache and show the blue bar buy the actually heavy effect isn't part of that cache. occasionally cache has weird interactions with proxy mode as well
for my 2060 6gb laptopcard only proxyworkflow with lb in the settings, make it possible to work with dv and fusion. in fusionpage are also Importent settings to know, if i want to see picture
I’m using DaVinci Resolve on an M1 iPad Pro. I have to cache everything… The Cache goes on an external 4TB HDD drive that is always plugged in when editing.
Related my Power Bins disappeared had to copy them from another Library (Project. On another note (Create subtitles from audio) worket fablously but ounce I messed around in the new VOICE ISOLATIONS Subtitles doesn work at all and I don't know how to get it back to where it first was BUMMER.
It is smaller, but which is the fastest? Because if i just want small i don't turn it on. It is maybe faster to watch it as a slideshow tht waiting minutes every time I change something. Because it is recomputing everything even is I just changed something at the end of the clip. For me atleast..
I have admittedly a bad workflow... I edit when I have time and in-between I leave DR (19 Beta 2) and when I do so with the "Smart" cache setting applied, my 4TB NVMe drive will completely fill with cache files. It takes hours for it to occur, but it will literally fill the entire drive and it really doesn't seem to matter what the project it. The problem is I must really not have my system configured well for optimum performance because I have an Intel i9-12900K, 64GB of DDR5, 2TB Boot NVMe PCI4, 4TB NVMe Cache & Render PCI4 and a 4070TI graphics card. That may not be the latest and greatest, but it should be sufficient to have near real-time playback on most things.
you might be able to! change your cache to User and possible toggle off more options in that project sections cache area so clips no longer automatically all cache and see if you still have real-time palyback

@@tib-c9265 Like Prores, DNxHR are very efficient intraframe codecs. The CPU hit would be so negligible as to be meaningless.

ooh I had wanted to mention the use case of rendering using the cache files...
Oh so you have a drive just for cache?! That's a good idea 💡
Interesting, I didn’t know there was a setting for compressor uncompressed, if you get the time, could you reply as to where that is please?
@Coatsey007 in project settings, at the botom of where you select resolution and fps iirc.
This lesson about cache management is definitely worth repeating. Thanks Patrick.

19 Freezes on Startup for me so I can't even use it. But I know it ain't specific to that cause 18.6.6 does the same now, currently stuck on 18.6.4
3 Years - 2TB off my external hardrive
I wonder if this might be why Resolve 19 was so laggy on me
Quick Update: When I intalled 19.02 Beta it kept all my previous settings from 18.6 and things are working as they should
great to hear!
Only 928 Gb I was shocked
Is 19 available or still in beta?
@migzzvizzion It's still in beta as of today.

also worth looking into Proxies and Optimized Media!
