How to Join Mp4 Video Files?

[2012Tony2012]

I have 5 x Mp4 video files I want to join into 1 file that plays from start to end, is that possible, if so, how?

iMovie should be able to accomplish this with ease.

Import your .mp4 files into iMovie first. Then make a new project, drag your files to the timeline back-to-back and then export the movie.

I am using iMovie '11 and it's taking 11 minutes to import 195MB of MP4 video files????

And then another 3 minutes to generate thumbnails???

Why so slow? And any way to speed it up?

I's converting the mp4 as it imports into a Quicktime file using the Apple Intermediate Codec setting.

And any way to speed it up?

Not really. It takes as long as it takes

The older the processor in your computer is, the longer it will take iMovie to get things done. If you think 11 minutes is too long to wait, I wouldn't even bother exporting it, because that's probably going to take an hour or so.

I found a way that speeds it up by 10000%. When importing DESELECT the "Optomize Video" and instead of taking heaps of time, it now only takes seconds.

So exporting takes ages, yes I noticed that.

So why is iMovie so slow to export? Any other app that's faster with same features?

Because it reencodes.

Some much better choices (I've also extensively posted on these here at MR forums at, say, http://forums.macrumors.com/showthread.php?p=15394130 - see my quick tutorial there) are iVI.

You can also give a try to QuickTime (even the non-Pro version built into OS X is able to join videos).

Finally, MP4Tools and MKVToolnix are also able to join videos without reencoding them - see http://forums.macrumors.com/showthread.php?t=1477358 .

Ahh yes. Forgot to ask about that, because I never have it selected. Sorry.
