Changes to grade discard Source Caches
Posted: Tue Dec 05, 2017 9:10 pmHi everybody!
It's time to discuss one of my biggest pet peeves with Resolve: The constant dropping and recreating of Source Caches whenever I copy/paste settings or sometimes even just adjust the grade. This has been bugging me since forever across all platforms, so let's treat this as a version-independent issue. There is also a good chance that this is not a bug but rather me not getting how it works. And yes, I have read the manual, watched tutorials and talked to other colorists.
So let's say I have my timeline of Alexa 2K and RED 5K footage. Timeline is HD and everything is set up. In the Color page, I right-click all clips and set Render Cache Clip Source: ON and then Render Cache to User. Red line appears, slowly turns blue, all good. Playback is smooth and colorist is happy. Apply a grade to shot 1 and move on to shot 2. Middle-mousebutton on the first shot to copy the grade and BAM! red line again, clip is being re-cached. Same happens when copying from the grade bin. And yes, I did select to Preserve Input Sizing and Camera Raw info, I would understand that those trigger the re-caching. Today I had a few clips that would even re-cache as soon as I touched ANY node. I think the affected clips had retimes on them though, but once it's retimed, it's retimed, right? Grading shouldn't trigger a re-retiming.
Has any of you encountered this behavior as well? Is that supposed to happen? If yes, what am I doing wrong? It seems easy enough and has been bothering me for too long now.
