QuickTime Can Combine Videos Into a Simple Timeline
We love all the little things you can do with QuickTime , but The Sweet Setup points out one thing I’ve never noticed before: the ability to combine a bunch of videos into one simple timeline.
Just open one video, then select and drag a group of videos from Finder over the first video. Once you release them, you will notice that you can paste them anywhere, reorganize them, and trim selected clips. When you’re done editing the jury, click File> Export to create a single file with your edit. This is extremely useful if you just need to slice a bunch of videos, but you don’t want to download an entire program just for that.
