I exportet a video several times with the "h.264" setting. The succesfully exportet vidos stops at some point and the screen either goes black or just freezes. The video is 30 seconds long and always exports normal.
I use h.264 and set my in and out points to where they need to be. Then I export without any errors or dialog saying something went wrong.
But when I play it back, it freeze frames before it gets to the end of the video but the play head still moves the remaining time.
I have exported using Mercury Playback Engine GPU Acceleration (Metal) - Recommended, Mercury Playback Engine GPU Acceleration (OpenCL) - Depreciated, and Mercury Playback Engine Software Only. The result is the same when I export from Premiere Pro and Media Encoder.
I uninstalled my Adobe Products and Re-Installed them, then re-exported. I was able to get an additional 3 seconds of my video before it froze again. Again I used both Premiere and Media Encoder to export with the same result.
This has just recenly became a problem as I use premiere and media encoder on a weekly basis and every video I have exported has been fine until now.
I am using Imac Pro (2017) with a 3.2 GHz 8-Core Intel Xeon W Processor and 8 GB Radeon Pro Vega 86 Graphics Card. I updated to MacOS Big Sur Version 11.3 but the problem happend before and after update of Mac.
