If PluralEyes couldn't extract the audio from your Premiere project, it's possible it's because of the way the media was imported into Premiere, or because it's not a supported filetype.
Regardless of the cause, you can try following these steps to workaround it.
We recommend you make a copy of the project first before following these steps.
- Open the sequence to be synced in the timeline.
- Select all the video clips in the sequence.
- Choose the menu item Clip > Audio Options > Render and Replace
- Sync with PluralEyes
