How can I join parts of a video together?

Video Join is intended for linking together parts of a video that have been broken up. The parts all need to have an identical layout including the same number of audio and subtitle tracks and these must be in the same locations. Also all parts need to have the same video resolution and encoding. It's not designed to be used for linking separate videos like say a movie and a video extras.

In order to use Video Join drag the first part of the movie into the iVI main window. Double click on it to open the Video Information window and then select the Video Join tab. Now drag the other parts of the movie onto this tab. You can drag them to rearrange their order. Once they are ordered correctly close this window. Now just convert the movie as normal and the resulting file should contain the parts linked together.
