DaVinci major timeline issue – please help!
I’m on the latest version of DaVinci Resolve (Studio 18 version 18.0.1 Build 3) running on a high end iMac with OS Monterey.
I have never had this issue before, but it just started a couple of Resolve updates ago a few months back. Like I said, before it was perfect, but a recent update has messed something up for me and I can’t find a fix.
I’m editing 3840×2160 60fps .mov files that were shot on an iPhone X and an iPhone 12 using FilMic Pro in 4k, 60fps using the FilMic Quality setting (I was using Extreme, but thought this was the issue so went to lower bitrate FilMic Quality).
The issue is this. When I grab the playhead in the ‘Edit’ window to ‘scrub’ through the timeline it jitters all over the place, like it’s jumping between quarter and 1 second, which makes it hard for me to scrub and land on an exact frame. It always scrubbed super smooth, but now it jitters and I have to scrub really slow, no more than about twice speed, to edit, which is really slowing me down.
The codec I shoot on is the HLVEC thing in FilMic Pro, but, again, this was never a problem before, just a recent DaVinci Resolve update has changed something, a default setting perhaps, what I don’t know, but it was fine in Resolve for the past few years, now it is jittery when I scrub.
I’ve tried deleting the render cache and changing timeline proxy resolution to half, but none made any difference.
Anybody have any ideas, again, it was fine before so it’s not my computer or the footage or the codec I’m shooting on as it was always perfect for the past two years, just the past two months it changed with an update to Resolve.
One thing does fix it, and that’s if I right click on a clip and click the ‘Render cache colour output’ – where on my clip I get a red line that slowly turns to blue. Once it is blue I can scrub and it is smooth as silk. The only trouble with this is all the clips I edit are about 18 minutes long and about 10GB in size and I need to make cuts about every 5 to 10 seconds to chop out a few seconds and as soon as I make that cut the blue line goes back to red and I have to sit and wait an age for it to render out again. Given I make about 30 to 50 cuts that red to blue would add up to several hours so it is not an option.
Also, this is stuff I do on a regular basis so I don’t want to have to mess about creating proxies etc as the time it would take me for all these 18-minute 10GB clips before I could edit them would take longer than me just editing in real time without scrubbing. I’m trying to speed up my workflow, not slow it down.
Any ideas as to what I can do to not have this jitter thing going on in the timeline when I scrub. Again, it was fine until last or last but one update.
I’ve tried re-installing fresh download of Resolve, but that does not fix it either.
I’m desperate for help here to get this working as it did a few months back.
