Just cleaned-up 400+Gb of cache clips, this is insane. Thank you very much Patrick!

[@anameyoucantremember]

Same bro, I just thought DaVinci cleaned up the cache everytime I closed the program. Boy was I wrong 🤣🤣

[@Fooney1]

350 gigs of my 1T drive...

[@MAGAMAN]

I regularly have well over 1TB of render cache.

[@PIXIT786]

@@anameyoucantremember HOW TO CLEAN IT WHERE IT IS LOCATED ??

[@leotexas3485]

Davinci Resolve suddenly stopped rendering my projects 5 days ago. After watching other KZbin videos, I suspected it was because my special effects and add-ons froze the program. Other videos advised to render the videos in place and make sure the "red lines turned into blue" before proceeding with the render. I did not see that on my end and could not figure out how to set that up - until I watched this video and learned I have to select "Playback >> Render Cache >> Smart" ... and now I FINALLY see what I'm supposed to see! And after it all rendered in place, it finally worked! Something so minor, but I'm still learning this software! Thank you for this! ☺👏

[@MrAlexTech]

You stop it… FIRST! ❤

[@ljocchino]

I'm a new dr user and fell victim to this setting. I was banging my head trying to figure out what was going on. Very few videos out there explaining this in the way that you have. It's an essential step to getting adequate playback performance. Thank you so much for providing the tip!

[@johnny9]

dude, I'm happy for you hahaa. Back when I didn't know I'd wonder why the heck my SSD would have so little space. Well I was using some heavy effects on uncompressed 10-bit! holy shmokes. Now I always go in a delete fusion cache after each vid render.

[@PhoenixNugget698]

This was me aswell, soo frustrating until I found this video

[@Nighterlev]

I didn't even know what these options actually did in Davinci Resolve! This video just improved my experience using this program by 10 fold.

[@DaneBrammage]

Another fantastic thread on making Resolve more responsive, Thanks Patrick.

[@majorediting8164]

Patrick…THANK YOU SO MUCH FOR THIS!!! I knew about the cache stuff but the settings have improved my systems performance dramatically!!!!!

[@vaud]

I'm glad I found your video, I'm fairly new to Resolve and I didn't know much of this. Thank you!!

[@EricSwanson1]

Patrick, thanks a million. I'm a new subscriber and I've been making KZbin videos since 2018. This was a great video. I'm going to clear a bunch of space. Thank you for the heads up and thank you for this video and all of your videos. Top notch content right here!

[@NoMercyFederation1]

After countless videos on this that were wrong your video just saved me and i got my video exported. I had so much masking it wouldnt even begin to export. After using the smart render cache and remasking it worked no problem.

[@edwardjski]

Super helpful and excellent explanation. Presentation was clear and conversational which makes it easy to watch and follow along.

[@RoadsofSilence]

This super helpful. Just to add clearing out that cache folder every so often is key along with these settings. If you don't you may run into an error that will say "critical error" and won't allow you to make changes to projects while open and will repeatedly happen if you have backup saves on a frequent timer. It's essentially a warning saying you may have run out of space (ask me how i know LOL). The error doesn't really make it clear that this is the cause but every few months if i'm not clearing out that cache folder I run into it. Anyways Love the content and plugins!!

[@patrykkuchniak3343]

New to DaVinci and to your channel, massive thank you for solving some of the problems I was experiencing!

[@theAstarrr]

You can also create proxies (lower quality clips used just for editing), there's great tuturials out there on that

[@Barrick_Creative_Media]

Great tips Patrick. Just been in, tweaked my settings and saved as default 👍😊

[@unclerichard6729]

Not sure why KZbin recommended this video to me 11 months after it came out but I'm glad it did. Working on a vid where I'm using learning to add effects, including your Proto V2 Effect plugin. It was taking quite a while for the effects to render and was still a little choppy during playback. Changing these settings helped a ton. Renders is seconds and playback is smooth. This computer is getting old and I'm glad I'm not having to replace it yet.

[@MrSuper]

I literally have a 500GB NVMe SSD in my system dedicated to Resolve render cache, and I kept running out because I guess it's set to uncompressed. Thanks for this video, as it reminded me to try changing the cache format setting.

[@likelovecomments]

Thank you very much.Decode thing works for me because i use clips taken from iphone :)

[@travelrhymesbymarufa]

thank you

[@dr.gregoryf.maassen2637]

This is an especially important setting to be aware of. We have an internal 2 TB SSD (Samsung) dedicated to caching only, and it would fill up very quickly when we edited one-hour documentaries. A hard disk that is set for the cache and has reached its capacity (meaning it is full) will result in many playback issues with the dreaded red no-media clip warnings. So, indeed, regularly monitor how much space you have left for caching, as DR will not warn you of a full disk. Thanks for sharing the video.

[@Forediting-dp9hi]

thanks man!!

[@BuGuedes]

sir, you just saved my life

[@Ruggedbeast]

Thank you for the help you are awesome. I always assumed render cache was just bad and that it cause me problem.

[@GuineaPigFacts]

Very good video, Thanks, I will those settings and clear my cache. I was wondering the other why my media drive is at 95% full. ;-) Now I know.

[@pianosfilipem]

thanks

[@kod_connect]

Wow. That was useful!

[@engouteyannick]

I'm halfway through the video and i can already see results. Is thanking you even enough ?

[@fotofyn]

This is simply brilliant! I just freed up 450gb of space after following your trick. Thanks !!!!

[@kirankiranmishra]

These are all hidden stuffs for starters - thank you for sharing

[@miketomas8564]

You are Absolutely Right! The average, Hell even the advanced Professional KZbinr doesn't need Uncompressed 10-bit files.. But try not to use a high level compression CODEC for these. That will slow down your editing performance. there's a reason you want light or no compression... Thanks for the Heads Up!

[@ProjectHelisexuality]

I've been using the highest version of DNxHR, but might switch down to the lowest. Also, you could play with the resolution if you don't need high quality playback while editing. I only ever use half the resolution of my 1080p files.

[@OLucasQueJoga]

Yup the last one was insane! I had more than 300 gb occupied by DaVinci for my KZbin videos 😂 insane! I even turned off cache media

[@DiegoGomez-pk5tg]

Bruh this saved me so much. I had 2.5 TB of cache files which was just ridiculous.

[@Taterzz]

i saw this happen to myself a couple days ago. had to look for the cache folder and deleted it. 100 gigs gone lol. going to roll with the SQ format now, that was a new tip.

[@GeeganGaming]

yep, just cleared out 20gigs worth of cache. THANK YOU

[@LandyVlad_Rides]

Thanks mate. Can you please do a detailed video about what is (as is not) actually included in projects, databases etc. Also the process for backing up projects / databases elsewhere (and restoring). And also save so can get new drive, reinstall windows and then restore all Resolve stuff as it was. I get pretty confused about all those things. Ta

[@gabuchancreates9813]

Thank you Patrick, I'm editing on an 8 yr old PC and even a small fusion preset will bog down my playback in the timeline, I was working in proxies, but figured out I don't think presets get made into proxies, only the footage? Anyway, there were a few setting I was missing, like the uncompressed and optimized media settings. Great tips, tyvm.

[@BlindIdiotGaming]

I didn't know I needed this vid. I am working with very little hard drive space. I didn't realize I had 40Gb of nonsense cluttering up my very valuable space.

[@alexsurmer]

very very usefull

[@EvilEustace]

I did try out the render cache thing few weeks ago. Was working on a 1h video and Davinci decided to create 220GB worth of render cache that I had to delete later. Now I know why XD

[@ombra30]

REALLY THANKS a lot. That's why it was better without caching

[@TerenceKearns]

I use h265 for proxies and ProRes 422 Proxy for everything else. I work on a low-budget system with not much storage space. I also force temp media size to HALF size. Largest video dimensions I use are 4K or sometimes Open Gate 6K

[@AlvynArt]

H.265 is higher compression and harder on the cpu isnt it?

[@thepro5926]

That "save as default settings" in the last (timeline settings) was surprising for me after 7 months of DR instalation!😂

[@schmutz06]

4:55 THAT is the ticket. I came here looking for exactly that breakdown. Just didn't know which compressed option to use. I gather this doesn't impact the final render in any way either. I can't believe I had 600GB of files on my NVME with a few minutes of fusion effects.

[@schmutz06]

haha I came back to this because I forgot to 'save as default' so a new project hit me with a 400GB+ cache... thanks TWICE for this video.

[@tristanrujano]

This is hilarious, my first video I did a relatively simple video edit that tanked my pc at the beginning of the video so I would just skip over it until it came time to export otherwise it would freeze

[@geodude4real]

Stars at 2:00

[@AarchiveRailways]

Thank you for this Patrick. I had a 1tb SSD that had one 1% left! Not anymore though.

[@KarolMurawski]

Just remember that DNxHR LB to HQ are only 8-bits. HQX is 12-bits. Use LB only if you have to, like on a laptop with small SSD.

[@Kshitijj]

This needs to be pinned!

[@DerHouy]

So you say, use DNxHR SQ or HQX? "DNxHR LB to HQ" what you mean with "to". Would be cool if you can clarify, I'm non-foreign (english).

[@KarolMurawski]

@@DerHouy 8-bit 4:2:2 is used in LB, SQ and HQ. 12-bit 4:2:2 is used in HQX. 12-bit 4:4:4 is used in DNxHR 444. Compression rates LB 22:1, SQ 7:1, HQ 4.5:1, HQX 5.5:1, 444 4.5:1. Do not use LB unless you have to. SQ and HQ are both the same heavy for CPU. HQX is more CPU heavy. You can also use GoPro Cineform which is even more CPU hungry, but has constant quality, not constant bitrate.

[@mariuswickli3206]

Why is it important to work with 12-bits when cacheing? When you are working/updating the Colorgrade the Cache shouldn’t be used anymore until you go back to editing and create another cache right? and for Editing Playback the 8 bit should be enough. I would be interested to get your opinion on that. cheers mate

[@KarolMurawski]

@@mariuswickli3206 Correct - you can use 8-bit cache for editing. For color grading it may be risky. Every node in a chain can be cached, so to prevent clipping more bits should be used. Also if you have source video that is 10-bit, you need at least 10-bit cache, but consider 12-bit to prevent clipping in node chain. And in Resolve you do not have separate caches for editing and color grading and if you need cache for editing, you may need cache for color grading, too.

[@bigrob029]

O. M. G. I was getting corrupted edits because of this. 298GB of garbage cache clips. Thank you for this!!

[@beeblet2]

thank you so much! just got rid of over 100gb of stuff. :)

[@AngelRuiz88]

I think the best form to improve the playback is use the resize node to playback at 720p

[@MaikKellerhals]

I had this problem after the first completely new project this year (without starting from a preset), it was set to 10 bit uncompressed and playback of render cache was slower and more jerky than without render cache. It took me a few days until i found this setting. I first thought the whole rendering was somehow bugged in the new version until i found out about this setting in some forum. I don't understand why this is on 10 bit uncompressed by default. Not even my (pretty high end) system could handle that (in 4K).

[@VincenzoDOnofrio]

Great man. This is what i was searching for. I want delete all render cache but there are projects that i'm not finish. Can i delete or it's a problem? Ciao from italy.

[@HarisCupina]

I am hiting my head, with what to do with fusion render cache for days end, the render employs %100 of HDD read/write, and as result I get lagging when press playback. That "Render cache format" on DDNxHR SQ solved it wow😮 . Also I would mention that I had to set Timeline Proxy Resolution to Full*, otherwise it wouldn't make a difference ❤. Amazing amazing amazing - this bottleneck is so silly 😢 thank you for the education.

[@cucumberforest]

with 10 bit uncompressed, the system does not have to compress and decompress the files before they are displayed and is therefore the fastest. The speed of the SSD is usually not the problem.

[@buzzdx]

i just figured this out yesterday, i cached a fusion comp but it still did not playback smoothly, even though the cache is on a ssd. changing to dnx lb made it work and playback nicely.
