VoiceOver Bug – iMovie Review

Whenever I make a project with and put an instrumentals that I created and try to record over it, it lags. I hate when this happens. I restart the app, I take off old projects but it still lags when I try to record “on-beat” over my instrumental. I don’t know if it’s a bug or not but if it is, please fix this!
