Davinci Struggling to Playback

PostThu Jun 03, 2021 7:13 pm

Hello,
I've had my good share of video editing experience on Davinci Resolve, but mostly basic stuff - now I started working with very good video and audio quality (4k and such) but it seems like having to deal with this many informations is chocking my pc's capacity when I do certain actions.

I often have to work with 2 timelines on the screen (one onto the other) and every time I switch from one to another (or every time I need to transfer a clip from one timeline to the other), my pc goes numb for 10 seconds or more.
I saw what was happening on the task manager and I realized that every time I did this, my pc went 100% on the CPU or on the project's footage disk; not at the same time, alternately. When this happens, I have to wait until it goes back to normal levels (from 0% to 40% percent) before I can start playing my video in real time again, and it doesn't do this gradually but all in one go, like if it just finished caching again the files on the timeline.

Sometimes it doesn't even "recover" and goes on loading for an undetermined time, until I close DV and open it again.
It happens both when my playback slider is on a clip or anywhere else on the timeline.

Am I missing something trivial on DV? Like the knowledge that it's an heavy program, doesn't matter what I do? Or that I need to have some option checked at all times? Or that I need to make proxies every time I start a new project?

Please tell me, dear Davinci Masters.

My OS disk is a SSD, while my project's disk is an HDD.

I'm leaving my specs here, if those can be of any use:

You didn't mention if you use the free version or the studio version of Resolve.
Also important to know is what kind of 4k material you try to playback (h264, h265, 10 bit, 422 or ??)

Your computer might not be fast enough (gtx 970 card is getting old )

hope it helps

Please uninstall and perform a fresh install of the application. Let us know if the Playback issue is fixed.
I have performed the above step and playback is smooth as i am using the proxy media of source as source quality is very high.

I normally edit in 1080p which is ok for my projects.

Have a nice weekend ahead. :D

Hello again and thank you for your responses; I use the free version of Davinci resolve with 4k h.264 material, no color or fx added yet. I know my GPU is outdated but this really isn't the issue here, since I've been monitoring that as well and DV uses mostly (or only) my CPU and the disk where it gets the footage from.
I noticed my PC does that loading thing also when I add simple stuff like a marker - the moment I press "M" it starts loading again without letting me having a smooth playback. This is becoming a stressful issue.
If it could be of any help I could record a video.
When I'm done with this project (I have to finish by today), I'll do a clean new installation, hoping it fixes the issue.
