BUG - M1 Mac Hardware and Software encoding issues
When exporting files I'm seeing a variety of different glitches with Hardware or Software encoding on the Apple Silicon versions of Premiere and Media Encoder.
For Hardware encoding I've seen:
If a frame hold has been added to our MOGRT overlays green flashing can occur on the exported file. The green flash affects the underlying image but not the overlays (only seen on h.264 exports so far).
If a clip has been slowed down overlay GFX can pop on/off over slowed clip. I normally use Optical Flow to slow clips when possible (seen on h.264 and ProRes422HQ exports).
Image size jumps a small about (on a single frame), or a non-sequential frame is inserted on clips that have been slowed down (seen on both H.264 and ProRes422HQ exports).
The glitches aren't always consistent, so they're not on all exports, and not always on the exact same frames. It also doesn't seem to matter if it's sent through Media Encoder (normally how I do it), or straight from Premiere.
For software encoding I've seen the following bugs:
Clips with master level Lumetri grade exported as a solid white frame. Other clips with similar master grades didn't have this issue, and HW encode exported with clip visible...but with some HW glitches as per above.
Export quality issues on some shots where SW export is badly compressed while HW encoding better.
Due to these issues I can’t really trust that files will export correctly with Apple versions of the software so I’ve been launching the Intel versions which seem not to suffer from these issues.
I’m using from Premiere 22.1.2 and Media Encoder 22.1.1 and am on an M1 Max MacBook Pro running Monterey 12.1
