"I'm converting my stuff for my Apple TV 1G using Handbrake on Apple TV preset, works great. However I would like to trim the beginning and end rid of the no use stuff, pointless having them, just to save that little bit extra. Is there an app to do this? I basically want to just trim the start and end of the video,a bit like what you can do on an iPhone for a video you took.I have Snow Leopard and iLife 09." ---- Apple Discussion
