How do u add your personal videos to your i touch through itunes?

In short, they must first be converted to QuckTime format, using the most recent QuckTime encoders. These encoders are available in most off-the-shelf video editing applications for both Mac OS and Windows, but if you don’t have such an app, then Apple’s QuckTime Pro is the best solution (btw it is $29.00 available through Apple’s website). Once they are in the correct format, a simple drag-and-drop into the iTunes Library will add the movie clip (.mov) into your library, then using the sync function, you can select the movie clip under the videos tab prior to syncing.
