Lost of my MP4-H.264-files (from Canon 80D, GoPro and DJI Phantom 4 Pro) which worked fine in Premiere 12 are now after the update to Premiere 13 not importable any more.

Changing the file-names from **.mp4 to **.m4v will solve it but just for new projects, the existing ones are now crashing or the media will be set to "offline".

The error occures on new and old files, not depending on framerate or resolution, and it occures on files that have been worked before the update (so that the container in the file has not been touched since)

I am really frustrated and dissappointed because of actually paying for Premiere and being not able to work with my older projects or creating new in a satisfiing way.

Please send me a comment and try to fix the bug as soon as possible
