I am editing videos of a podcast with a looping video over it. The mp3 files range from 20 - 40 minutes in length. When I import them into Adobe Premiere, the files have an extra 1 - 2 seconds of repeated audio at the end. When I bring them into Audition, they stay the correct length. I calculated the amount of frames the file would have at 30 fps and 29.97 fps and it adds up to the additional seconds. I attempted to change the "Indeterminate Media Timebase" in the media section of preferences to match my file, but there is no change to the file when I re-import it. I was able to convert them to .wav and the issue was solved, but is there a way to fix this rather than converting all the .mp3 files to .wav?

Premiere Pro just doesn't like mp3 files sometimes.
It is best to convert to wav because even if mp3 files work initially, they could cause issues with the project in the future.
figured as much, was just hoping I didn't have to convert them all.
It's never a good idea to use MP3 as your source files if at all possible.
Not only are they lossy, but they also lose sync.....
If I had the choice I wouldn't have, but you take what you're given by the client.
Thankfully converting to wav is pretty fast.
