I'm using the Beta on Mac Mini M1, 16GB RAM.
I exported video using H264 with AAC sound, and the output had a strange sound to it, like the audio was far away, and mono-mixed-down or something.
Switching to MPEG audio got rid of the issue, so that's my temporary workaround.
I'm back with more details. In this zip file, you'll find:
- WAV export (sounds exactly right)
- H264 exports for "AAC", "AAC+ Version 1" and "AAC+ Version 2".
The "+ Version 1" sounds the closest, but none of them sound right. They all have artifacts that sound like you're in a tunnel, or listening through an old telephone.
Do you have a solution?
I have the same problem.
Not really, my workaround is to export ProRes with Uncompressed audio and then do my compression in another program.
