Edit .mp4 (.m4v) video encoded by Handbrake

According to this thread in Handbrake forum, I have tried to trim Handbrake encoded .m4v file without re-encode whole video.

It worked nicely.

Work flow:

  1. Download MPEG Streamclip from this site.
  2. Open .mp4 file with MPEG Streamclip.
  3. Set in-point and out-point, then trim it.
  4. Save file in another .mp4 file.
  5. Change extention to .m4v

iPad default video player could play it without problem.
