How can I merge .m4v files?

Question

I transcoded a DVD into several m4v files with HandBrake. How can I merge these files into one m4v movie?

You can use the built-in iMovie app to do this.

Create a new project, add your video files, and drag them to the timeline in order. Export your project as an M4V (Share-> Export Movie).

If you're completely new to iMovie, some good introductory tutorials can be found on YouTube.

	Why do you say "built-in"? – GEdgar Jun 28 '11 at 3:06
	@GEdgar because iMovie comes with Mac OS X. It's 'built-in' to the system. You're right, it probably isn't the best choice of words, but it is true. – Nathan Greenstein♦ Jun 28 '11 at 3:15
	Thanks for the response. It is almost correct. iMovie cannot handle M4Vs. So you have to go back to HandBrake and output the movies in MP4 format. At that point, you can use iMovie to stitch them together – Julien Chastang Jun 28 '11 at 22:31
	@Julien iMovie can handle anything that QuickTime can, including M4V videos. Unless you're using some strange codec, you should be able to use them... – Nathan Greenstein♦ Jun 29 '11 at 1:30
	I tried importing m4v movies but find the two I want grayed out. A third one is selectable. All movie files were created by Handbrake and all are m4v. Any ideas? – Andrew J. Brehm Jul 2 '11 at 16:48
