iMovie is strange. Everything it does it does with an unexpected twist. Nothing works as expected. It almost seems they do it on purpose.
Take reverse. It’s a simple task: I want my video to play backwards. You either have this function or you don’t.
But not with iMovie. When you reverse a video in iMovie, you end up with a video three times as long. Why? Because it plays forward, then backwards, then forward again. Why? I don’t know. What’s worse, it does not create three separate segments for that, so I can’t easily delete parts I don’t need. And it displays some sort of control on top of each part, but it doesn’t snap to them and they have pretty huge gaps in between, so positioning my cursor exactly when video changes direction is impossible.
You know what? I’d prefer iMovie doesn’t have reverse function at all.
