I get your frustration. Completely. But, you mentioned, "the last few years." Have you upgraded your computer since then? Are you on a mac with more than 16 cores? This thread might be the unfortunate answer to your issue. Take a look and let me know if it seems to fit your situation.
I've checked that thread, but it doesn't seem to be my case.. pretty similar, but not entirely.
My Mac has 4 cores - so that's not it - ruled that one out.
And yes, I did upgrade my computer since then - running on Sierra 10.12.6
What's weird is that I do not even see the H.264 listed in the "Video Codec" options for Quicktime format when I export in Premiere Pro and Media Encoder. It's just not there anymore. Why am I missing it?
Did Adobe removed it from the codecs available for export with Quicktime?
Is there a way to get it back there?
Or an alternative?
Thanks so much everybody
I know when I was having codec issues sometime ago I simply installed VLC player and the issue I was having with playback seemed to fix itself. It was a different issue and was on a PC but thought I would throw it out there. VLC includes a ton of codecs
H.264 exports are simply handled in the mp4 format. So ... QuickTime options are basically Animation, DV, DNxHD/R, and Cineform. And some other mostly variants.
