Update 12.1.0 won't import/export .mp4 or .mov

[henryd19878404]

Since updating to 12.1.0, Premiere Pro has made my work hell.
It no longer reads some mp4/mov files, instead reading the majority (but not all) as audio files, it also is a hit and miss exporting as it gives me error warning and refuses to export. I've tried deleting Cache Files, didn't work. Reverting premiere back to the last version works but then I cannot open my recent project, if I start over I've lost a day of work, another half a day trying to fix this problem.
I was excited about the new update, but this has shaken my trust with Adobe.

Mov might be due to this:

mp4 should import just fine.

As for going back to previous version try this:

Open a New Premiere Pro Project on an Older Version! New PP Project on Older version, no software! -...

Lol "JUST FINE"

It is "FINE" but it doesnt compare to .mov  is there a way to export a mp4 that is almost lostless in quality or that is alot closer to mov. because any of the setting for mp4 that i have found dont compare to h.264 mov

[Ann Bens]

It seems H.264 in mp4 is based on H.264 mov. And are the same quality.

[BrandonKirchhofer]

Have you tried it? because i have. if you export with the format h.264 then choose one of those presets. My final file is like 70mb. when i export through quicktime then select h.264 i get a larger file size of arond 1 1/2gb-2gb. MP4 does a extreme compressesion to get the file size down to 70mb. but quicktime give you way more inforation that I need.

Hi all,

We're aware of the import issue with H.264 files and are working on a fix.

Thanks,

What's happening?  Which version works?

6 months later, and .mov's won't import in AE CC, even with Creative Cloud doing whatever updating it's supposed to be doing. And is is supposed to be doing... isn't it?

[R Neil Haugen]

From your  "help/about" menu, which number-dot-number version of which app are you using?
