Joining MP4 Files together without Re-Encoding (Windows and MAC)

OPTION 1 - MP4Join (Cross Platform) [RECOMMENDED!]

VERY simple cross platform solution to join MP4 files. Just add them to the lit, re-order them, and it will simply copy the next video on to the previous at the end of the last frame. It will output the final MP4 without loss of quality or re-encoding.

OPTION 2 - Quicktime (7 or X at time of writing). Windows users must use Quicktime PRO ONLY.

1. Open the two H264 videos in Quicktime 7. Let's suppose they are named video1.mp4 and video2.mp4.

2. Working on video1.mp4, Select All, then Copy.

3. Switch to video2.mp4, make sure the "cursor" is at the beginning of the video, then Paste. This inserts the content of video1.mp4 at the front of video2.mp4.

4. This step is probably optional. "Save As" the modified video2.mp4. You will be able to save in .mov format only. I saved as a self-contained movie, but I suppose a reference movie would work too. I used the filename "".

5. Select "Export" in the file menu to export to the joined H264 file. The "Export" to select is "Movie to MPEG-4". The preset is not important, I chose "LAN/Intranet". The preset is not important because we override it in the next step.

6. Click on "Options" to reach the settings dialog. In the Video pane, "Video Format" is selected to be "H.264". Click on the menu, select "Pass Through". As expected, all the other options will get disabled.

7. Click OK, then Save, and watch your joined file be saved at the speed of your hard disk.

OPTION 3 - MAC Users Only!

SimpleMovieX, a shareware video editor which exactly advertises this as a feature. Requires OS X 10.6 or later.

iMovie is a good choice for joining MP4 and MOV. But it is not compatible with many video formats.

What if your source files are AVI, WMV, MKV, AVHCD, MXF, WebM, OGV, 3GP, MTS, etc.

I just found out a detailed guide on how to merge various kinds of video and audio files like MP4, MOV, AVI, WMV, MKV, AVCHD, SWF, MP3, WAV, etc at:

Hope it will help you more or less.
