QuickTime and MP4 audio sync
I’m not sure if anyone’s noticed this, too, but lately audio sync is horrible with H.264 MP4 files playing in QuickTime player and VLC. The same files are fine in Switch. I can upload those files to Frame and the playback from Frame’s player is also fine. This is on Catalina Macs. I haven’t tested this too much with Big Sur, but it wouldn’t surprise me if it happens there, too. These are typically files created via Premiere Pro direct exports or through Adobe Media Encoder. Thoughts?
