I can't see my exact question having been answered, so I'll give it a go. I have some non-protected videos (personal stuff) in m4v format that was created from DVD using Handbrake. I would like to edit these files (cutting out parts) and merge them together. Easy enough. QT Pro does that. But I want to save it straight to the current m4v format. QT Pro, when it saves edited m4v files, converts them over to mov files, which I want to avoid. Anyone know of a program that can edit/save m4v files without having to convert them at any point in the process?
