If you want to show multiple Animoto videos together, for example for burning to a DVD or as part of an extended slideshow, you may wish to join multiple MP4 files into a single file.
To join multiple MP4 files into a single file we recommend that you use a piece of software called MP4Joiner. It is a simple, free tool available for Mac or PC.
Download MP4Joiner here: http://www.mp4joiner.org/en/
Press the “Add Video” button to select your MP4 files.
Once added, press “Join” and select a destination for your joined MP4 file.
For best results ensure that you are joining files of the same resolution, eg. all 720P MP4 files as opposed to mixing 720P and 480P.
