Trim videos frame by frame.

You're cutting down a video clip and you nail the exact frame where the action starts. But then you second-guess yourself. With the new trim feature, you can move those edit points down to the individual frame, and if you hate it, you've got 24 hours to undo the whole thing.

The payoff is real if you edit a lot. You can be aggressive with your cuts, knowing you're not locked in. Move on to the next clip, come back tomorrow, and your original is still there waiting.
