I created a screencast using Snapz Pro X that gets saved in .mov format (H.264, AAC). I want to just cut a few seconds off the end of that file. The only video editor I know of that's installed on my Lion machine is iMovie '11. Can I use iMovie to remove part of the end of the video, but maintain the same dimensions (1146x1057)?
I tried to import the movie, create a project with just the parts I wanted, and then export via "Share -> Export Movie", but this:
- makes the resolution worse
- alters the aspect ratio
- increases the file size
