imovie freezes exporting
I have an imovie that's about 2 minutes long. I need to export it and put it onto google drive. However, whenever I start the file export, the little pie chart that shows how much has exported stops and doesn't move. I have over 300GB of storage space left, so that shouldn't be a problem. imovie functions normally while it's "exporting". Also: whenever I play the unrendered video, the video lags quite a lot at various intervals. I am literally questioning apple's product quality right now, so I'd prefer an answer quite soon. Anything you know helps!
