Hello there, i have an issue with retiming. when i change from nearest to frame blend or to optical flow the color grading dissapears but only in the preview. Of course i deleted the render cache for rebuilding it but the problem persists. Changing tonearest the color grading comeback again and everything looks normal.
Render cache format is DNxHRX, DR runs on W10 64 bits i9-9900k +32 GB Ram + Nvidia 2080Super

The final render is OK, but it is a little bit annoying in my worflow. Any Idea?

What version of DR? Updating your GPU driver couldn’t hurt as a test.


HPz840 - 2x 14 Core 2.6GHz - 64GB RAM
Windows 10 Pro 20H2
2x RTX 2080Ti (SD 460.89)
Resolve Studio 16.2.7
Decklink 4K Extreme (11.6)
FSI CM250
Panasonic FZ1000
Mini Panel

Thanks for your reply.
well...its DR17 with the latest Nvidia drivers.

I just discovered that its only happening on one specific clip with light Rays and a power window with tracking...disabling that node everything goes well.

The Problem is still there but now i know the cause.
