MP3

PrPro has never really accepted mp3 files. Typically you need to use MediaEncoder to convert them to wav files, then import those to Premiere.

And of course, you can do batch conversions or set up 'watch folders' where you drop a clip/clips into that folder with Finder/Explorer, Me auto goes to them, converts/transcodes them with the instructions you set in Me for that folder, and puts the converted/transcoded files into the folder also specified in setting up the watch folder.

I know there are of course requests for this to be added, I'm just commenting about what simply works now.
