iMovie Audio Not Processing

Ever since the latest iMovie update (10.3) it is taking hours for the audio to process. I'm putting a video that is approximately 40 minutes long into iMovie by dragging and dropping from my desktop. The video shows no audio at first, only diagonal lines where the wave form should be. I can't play the video in iMovie because it has no sound until it processes, so it's hard to edit. If I try to export the file it takes hours (4-5 hours). I create several videos like this every week and have done it for years and it was always very quick. Only since the latest update has this issue arisen. Is anyone else having this problem, or does anyone know why this is an issue? Secondly, is there an easy way to roll back to the previous version until this is resolved?

MacBook Pro 13″, macOS 11.6

Other posters have experienced audio processing issues and long export times with iMovie 10.3. It's probably something that Apple will need to address in a future update.

As for reverting to your earlier iMovie 10 version, you can do that if you have a Time Machine backup and can then restore to the earlier version. Although I am not entirely sure of this, if you have opened your iMovie library in iMovie 10.3, then the library will have been updated and may not open in your earlier iMovie version. So, you may need also to restore your earlier iMovie library. Not something I have had the necessity to do myself, but just wanted to mention.

Here's a link to a thread where the poster had a problem similar to your. Maybe my comments in there will help you:

If nothing you do fixes this, you might want to contact Apple Support and talk to the techs there. The techs there have the capability of remotely accessing your computer that we cannot do here. To contact apple support click on the Get Support item in the upper right hand corner of this forum’s screen. Navigate to a place where you can enter your phone number.
