Hi, running OBS version 31.0.1 (64bit) on a Mac mini, Apple M4 chip, 10-Core CPU, 10-Core GPU, 16GB Unified Memory, macOS 15.3. I have the following settings in OBS:
Output > Recording
Recording Format: Matrosca Video (.mkv)
Video Encoder: Apple VT HEVC Hardware EncoderLog files

When I hit record I get the following error message: Starting the output failed. Please check the log details. Note if you are using NVENC or AMD encoders , make sure your video drivers are up to date.

If I change Video Encoder to: Apple VT 264 Hardware Encoder, I get the same error message, however if I change the Video Encoder to x264 it records OK.

I have updated the Mac Mini as I believe this will have updated my video drivers also. The weird thing is after updating the Mac Mini it recorded fine on all 3 Video Encoder setting, but then starting giving the error message again when using HEVC or VT 264, and now will only record on x264 again.

I have included the log file, I anyone has any suggestions of how to correct this it will be appreciated. I believe it is best to have the Video Encoder set to VT HEVC, but more than happy to take advice of great knowledge.

Thanks in advance.

For what it's worth, in my case it appears to have been something I botched in initial setup. Deleted the app AND my entire ~/Library/Application Support/obs-studio directory, reinstalled the app, and it now works.

NOTE that this probably blows away any settings you've made; it was OK in my case as this was a new install. (I did initially try just deleting and reinstalling the app, but my just-configured Source persisted, along with the problem.)
