I might have to downgrade from Catalina because I can't get iMovie running smoothly. I have some video editing I need to do. I'm running 10.15 Beta (19A512f) and the latest iMovie (software update is not telling me there is an update to iMovie available).

When I import a video from my iPhone into iMovie on my MBP the video only plays a short while then stops. I have tried several videos imported from iPhone and it's the same problem. However the videos play perfectly on the iPhone and in Photo app on my MBP.

Is this a known problem? Any solutions?

I have not installed Beta 5 yet. Will installing it solve my problem?
