This is fascinating for someone who, back in the '90s, did a little work with Apple's QuickTime MOV format files, and also has some interesting notes about why you may have experienced audio sync issues: OBS Studio: Writing an MP4 Muxer for Fun and Profit

Wow, I had no idea that MP4 was based on QuickTime! I used to own the "Inside Macintosh" volume about QuickTime, and at one point - due to a contract job - had a fairly detailed understanding of the format and its API... but MP4 I always imagined to be some obscure, cryptic, Fraunhofer Institute-developed sort of thing. Wild to learn, all these years later, that it has basically just been '.mov' all along.

We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
