I’ve of two-minds about this technique. I’m intrigued that Final Cut decided to include it and I can’t, for the life of me, figure out how it would be useful.
Anyway, Final Cut has the ability to do asymmetric trimming. What that means is that you can trim the video in one direction, while trimming the audio in the opposite direction. Here’s how it works.
What you’ve just created is a split edit. While this is quite neat and I hope you find it helpful, I never use this. And the reason is that I never want to trim my audio and video by the same, but opposite, amounts. My issue is not with the technique, but the symmetry.
I use split edits all the time, but first I work to make one edit point, either audio or video, perfect. Then, I use Option+Roll to split the edit point that needs adjusting. I can’t think of the last time that I needed to move both audio and video by exactly the same amount in opposite directions.
My Avid friends tell me that they use this technique all the time on an Avid, because it’s the easiest way to create a split edit. For me, using the Option+Roll tool is much faster and easier.
Tom Wolsky adds:
Asymmetrical trimming is only useful if the video supports it. For instance in dialog if you have a pause at the end of one shot and a pause at the beginning of another, you could just cut the pauses or you could asymmetrically trim them to create a split edit at the same time.
