When a video file (.mov recorded on iPhone) of resolution 1080x1920 is trimmed in QuickTime and saved as 1080p, the saved video resolution is 607x1024.

Is there a way to trim video and keep the original video resolution?

p.s. QuickTime Version 10.1 (501.22) on Lion

Just trim your video on the iPhone, in your "camera roll". This is the only way I know won't re-encoding the video.

  • Seems dumb, but this is actually the easiest—and seemingly the only —solution.
