These are instructions on how to quickly combine (join) two or more MP4 video files using your Mac. We previously published a tutorial on how to combine video files using QuickTime. Using QuickTime places the video in a mov container. In some cases this may be a problem.

Follow these steps to combine multiple MP4 files using MKVTools.

Step One
Download and save MKVTools from here to your desktop.

Step Two
Double click to extract the zip archive.

Step Three
Drag the MKVtools app from the extracted folder into your Applications folder. Then double click it to launch the application.

Step Four
Click the Tools tab at the top of the MKVtools window.

Step Five
Open a Finder window and navigate to the location of the video files you would like to join. Make sure that the names end in 001, 002, 003, etc. where 001 will be the first video in the join queue.

To rename a video simply select it and press the Enter key to modify the filename.

Step Six
Highlight all the mp4 video files you would like to join then drag and drop them into the square box within the MKVtools window.

Step Seven
MKVtools will now join your MP4 files. A dropdown drawer will appear to display the status of your join.

Step Eight
Once complete you will notice the combined video file appear in the same folder as your source files.

I just use copy and paste in QuickTime I think I have the \"Pro\" though. 1. Open first segment, scroll to the end. 2. Open the second segment, Select All, Copy 3. Return to the first segment, Paste 4. Repeat until all segments are combined.
