    From the title, anyone know of a good program to crop MP4 files without re-encoding them.

    I may know one and just not realize it, or remember it.

    Any cropping requires a full reencode. There is no such program. About the best you can do is to do an on-the-fly crop while playing the video (ffdshow).

    Might be possible since MPEG uses Blocks and Slices. But so far, no apps have been made that would support cropping on Slice boundaries, while maintaining the rest of the DCT info.
