This is not a bug - you have a problem reading and writing to your cache. I run the Resolve user group on facebook - there are 150k members there and I haven't heard one person complain of this. The closing and reopening is going to have your cache refresh. You need to check your drives where you have the cache writing to. It might not be fast enough to re-render on the delivery page if you have other things using your resources when it's writing your file.
I've had this issue before & it seems it a render cache issue. If change your render cache to from smart to none or user, it forces an update. Not a complete fix, but quicker than quitting davinci.
@DuanToOthers I wanted to write the same comment. But I second this man's one. Before hitting render just turn off cache or delete the existing one. That will sort all of these issues out. Usually Davinci is smart enough to not use the cached information to render. But you might have ticked the setting where Davinci is instructed to use the cache to speed up the render. So either way if the cache is bugged it is better to discard it before the final rendering.
In regards to the render cache I got the best results in Davinci when I don't use it at all or only to preview a heavy fusion composition. Honestly if I were a Davinci Resolve creator I would make a whole video about that topic. When it comes to performance VRAM is probably the number 1 problem for most people. Most people aren’t pros. They might have a beefy cpu. But than sit on 8gb of VRAM because Nvidia is a stingey pos. With 8gb vram you run out of space on a 1080p project of 15m runtime video in 10 to 20 minutes easily after opening it. From there on everything gets choppy. And the only way to fix this is to close davinci and reopen it. Rinse and repeat. Davinci just fills up the VRAM and barely frees up anything. And to me the 8gb vram is the exact sweat spot of trash. Not low enough to outright crash but nowhere near enough to actually work properly. Once that VRAM is full Playback gets unbearable. Just check your taskmanager and open the gpu panel while editing and you can observe it live. Thats where a lot of people look at the cache in the hopes to find a fix. But in my expeirence it makes it worse. Processing the cache often creates additional overhead. And I often experienced that it ends up making everything slower than not using it at all. So I just stopped using it. If I need to preview an effect I turn it on briefly. See if I like the result and then turn it off again. And then either I render it out in place. Right click there is an option for it. Or just move on. I also don't use the option that makes the video 1/4th resoltion. It just creates more processing overhead as it needs to convert one resoltion into another. So it slows down instead of speeding things up. The most important part for performance are the proxies. Don't use optimized media. Set them to the lowest you can. 720p is enough for all purposes. Timeline resoltion also should be the same than. For some reason the windows native format is slower than using mp4 for my proxies. You should try it out. But on my Intel/Nvidia setup it is more performant. This simple setup makes it so that my VRAM actually has a gb to spare in the end. And technically it won't even matter if your final render is 4k or 1080 since you are editing in 720p and change it later back. So aside from frequent bugs the cache is a performance issue for me. Not an improvement. Very funny stuff. Hopefully this helps.
@@NeoStarImpact hi i'll try the lower 720p for editing, but saying that it's not that the timeline becomes choppy, the program after a period just locks up and windows spinning thinking about circle appears then it all jumps back into action after 15 secs of hanging. This was far more frequent before i bought the SSD and placed cache location at that drive vs hdd i had to start with as i didn't want to fill my c drive up, i try to keep that just for windows madness.
This is totally true. 19 is a buggy mess and I wish I stayed with 18. I was finishing up on a 4 year project and the exported video has a bunch of bugs. I have random frames that sometimes have glitches... audio sometimes disappearing.
Woah, it’s not a buggy mess. Maybe something incompatible on your system but don’t claim the program is like that for everyone. Most stable editor I’ve ever used, and I’ve had a few of them.
I notice consistent issues with audio caching since 18 when I started using DaVinci consistently-where my audio goes silent randomly. I'm now in the habit of simply caching an effect or two, then leaving it on while working on the clip with different effects and plugins and then turning caching off, or bouncing the effects to the audio clip once I'm satisfied. Sometimes I need to turn audio caching on and off a time or two to get the audio clip to cache, too. Haven't noticed it with video yet, thankfully.
I've had an audio issue in some versions of 19x. The audio will quit and after a couple of minutes the program will crash. I can usually save my work in time.
The only bug I notice is you can’t pull in emoji names files and when I scroll it scrolls too much… L patch for Davinci, especially after using it for 12 years
I have the same problem, so I put an adjustment clip above and the fade works then. I'm still waiting on BlackMagic to reply after I sent them the Log file.
I experienced two 'bugs' (i say 'bugs' because maybe i just have some settings wrong. cache...etc...): - Sometimes when i cut off a bit from an audio clip or change volume, the clip plays back a completely different clip. Only fix is to close and reopen davinci or cut the clip and paste it back in. - the waveform sometimes has an offset of 5 seconds
Running 19.03, have not had this issue. I have noticed, even with previous versions, that things run more smoothly (faster) if I close, and sometimes restart my PC,. But in general, haven't had this problem. PC, 64 g RAM, AMD CPU 5900x, AMD R 1Tb SSD C drive, 4 Tb SSD working project drive. Suspect Jim Rogers-colors is onto the solution.
Tbh i fight this program every week! One min audio plays back then it doesn't, changes suddenly stop realtime, it hangs for no apparent reason randomly after being smooth for hours. I've got i7 cpu 32gb ram, rtx 3060 8gb, separate ssd for media, although just onboard sound. I'd have thought my spec would be fine? As you say, if i close dv and also reboot my pc, it goes back to normal. kinda crazy
@MrDeliveredFoodReviews it is the 8gb vram that makes you fight davinci every week. Just have a look at the taskmanager and see how much is taken while you edit. You can see in real time the moment it filled up that playback becomes choppy. Doesn't matter how good your other specs are. You could have an i9 and 128gb ram. Your PC will still lag. I made comment on that video how to make the playback experience better for those that have low vram.
@ when u say vram im referring to gpu ram at 8GB on a nvidia RTX card...how much does dv need? lol ive never seen the card spike to 100% as i regularly have tm open on the background and monitor heat / usage via hw monitor
@MrDeliveredFoodReviews honesty depends a lot on what you do on dw. I actually have a some fusion effects going as I educational content. For my VRam is always maxed out.
@ i tried the timeline and project swap to 720p and seemed to help. but again after 4hrs of dv working now smoothly it starts doing the locking up spinning blue thinking circle - very weird, like a memory leak
Thank you for your content, I really appreciate it! I'm currently struggling with Davinci's unreliability when it comes to audio editing. Sometimes a few seconds of audio are missing at the beginning after rendering. Sometimes there are audio dropouts or temporary synchronisation problems in the edit page. Has anyone experienced this too...?
If you got this problem make sure to turn off your cache before rendering. And if you are in the midst of editing purge your cache. That will force davinci to fix the issue.
I've had the same issues as you Duan, and same fix. Also I have had an annoying sync problem with imported phone video recordings where the voice & visual are out of time with each other, I manage to fix this with an app 'HandBrake' which has many syncing options within the program. Another fix I used for fade in-fade out is creating a second timeline. Thanks for your video.
19 has seemed more buggy in general and after hearing people recommend it in previous versions for being very stable im alittle disappointed. Overall it's a great program but 19 seems more buggy to me, just alot of small annoying things that build up...
Weird, I've never experienced this in any version of Davinci. There must be an export setting that will solve your problem. Maybe disable the use render cache in export?
Has this been reported to the guys at Da Vinci. I have had problems like this with Cyberlink Power Director which is why I moved to Da Vinci. I don't like Adobe software nor its bloatware.
Lets see, so you post this, waisting peoples time, because you have this problem in Resolve, and you want to go back to Premier, because Premiere doesn't have bugs and its perfect, then go back, I don't care.
I havent come across this bug yet but in general I have a feeling DR 19 is less stable than the v.18, not to mention that it is slower (especially when rendering) than the previous version :(
I had this since forever. And I do have an absurd amount of RAM. Almost a 100 GB that even Davinci doesn’t fill up entirely. It goes to 70gigs for me. The problem is the VRAM of the gpu of mine. I do have only 8gb that gets filled to the brim in 15 - 20 mins working on a bigger project. This sounds counter intuitive but it is actually best to have the render cache turned off. It is only good for previewing an effect. Otherwise it just creates more processing overhead. Once you are happy with an effect abuse the function of "render in place" to turn any heavy fusion composition into a regular clip. Having those things stuck in your VRAM is not gonna help. Always use proxies. Don't use optimized media. Make the proxies as tiny as possible like 720p. I use the mp4 format for my proxies as for the some reason the Windows native format is slower on my machine despite having an RTX3070ti. So give mp4 a shot. There is a setting where you can set the viewer resolution to 1/4 via the menu at the top. I noticed that it's better to just don't use it at all and let the setting be the original size. Since your proxies are 720p already anyway there is no need. Changing that setting to lower creates again processing overhead as your system needs to process on the fly from the 720p to 1/4th of that. Timeline setting you should chose 720p at 60fps if 60fps is the format you want. The fps is the only thing you can't change so there is that. The resolution won't matter for rendering as the rendersetting will overwrite the timeline setting. And if for some reason it doesn't you can always go back and change the timeline resolution to what you need. These are the things that actually made resolve behave for once. You still need to do your occasional restarts. Especially after your computer comes back from sleep. But it will be more bearable. The issue can fundamentally only be fixed with more VRAM. 😢 But the tips I gave should help.
That happens when you are at the very end of the first clip or the very beginning of the second. The transition needs a few frames to work with on both ends. ;)
I am a subscriber for a while now A client send me Sony video which has mxf audio which has drop outs on playback. Exports fine, but playback is very glitchy. Any thoughts?
@@DuanVanSchalkwyk what GPU and how much RAM you have (also how fast) ? I got no problems on 19.0.3, but from what you have described, it seems to be a rendering cache problem. Try to manually delete the cache and try again. OR you have a very bad/damaged SSD.
OMG yes! This isn't just v19, I've noticed these kinds of bugs (especially with audio) since I started using Resolve at v17. Their caching system is extremely buggy and it's really annoying. Sometimes manually deleting the cache folder fixes it, but not always.
Don’t need the clickbait shite either, you may have an issue with a fault with the cache but you made this sound like the program is flawed in more ways than that. 👎🏼

I can check that out but my cache drive is an external SSD(1gbps).
@@DuanVanSchalkwyk that sounds very slow.
you should NOT place your cache on a slow external SSD. What were you expecting=
