How do you fix There Was an error decompressing Audio or Video in Premiere Pro?

To begin, the first thing you need to do is check/test the file you are using, so listen to or watch it in VLC or another program from start to finish without fast-forwarding. If it plays without any issues, you know the file is fine.

Try converting the file to a different format, then add it to your project.

If the file plays fine and doesn’t have any visible issues try converting it to a different format if it is an .mp3 file convert it to .wav. If the file is anything other than MP4 try converting it to MP4. MP4 is Premiere Pros preferred format so if you can, try to use that wherever possible. Once you have converted the file, open Premiere Pro again and add the new file, I generally like to rename it for good measure as well.

Try clearing the Premiere Pro Cache.

Another good fix for this problem is to clear the Premiere Pro cache. This will remove any old junk files and potentially corrupted data. To clear the Premiere Pro cache do the following.

First, open Adobe Premiere Pro.
Then click Edit >Preferences > Media Cache.
Here click Delete under the Media Cache Files section.
Now accept clearing everything and restart your computer and you shouldn’t have any issues with exporting/encoding anymore.

Make sure that you have enough space on your drive.

Another important thing you need to make sure you have is plenty of free space. Premiere Pro has a tendency to get unstable when there isn’t at least 15GB of free space left on the drive that it is installed on.

Uninstall and reinstall Premiere Pro.

Yep, the worst option of all but you will need to uninstall and reinstall Premiere Pro to make this problem go away. Just make sure that you keep a copy of all of your project files otherwise you’re going to be starting everything from scratch again.
