[BUG REPORT] I444 H.264 recordings no longer work with DaVinci Resolve


New Member
I444 color format (4:4:4 chroma) is already a fickle format and Resolve is one of the few editors that work it with properly.

After OBS Studio 26.1 Release Candidate 1, I444 recordings are no longer readable in Resolve: https://github.com/obsproject/obs-studio/releases/tag/26.1.0-rc1

I tried OBS Studio 26.0.2 and this issue is not present, I444 recordings work fine: https://github.com/obsproject/obs-studio/releases/tag/26.0.2

I can see that OBS Studio 26.1 Release Candidate 1 update logs mention the following:
  • Updated dependencies on Windows (such as x264) to their latest versions for the latest performance improvements [Jim]

Could this be what has caused I444 recordings to break?

Log file for 26.0.2: https://obsproject.com/logs/zrlX_cf6PGqrry_J

Can this issue be looked into?
