If you have a cool video on your computer that you want to put on your phone, follow these steps using iTunes.
First, drag the video from your desktop into iTunes. You don’t have to put it anywhere special—you can see that I just dragged it in while iTunes was still in the music view.
Next, select the movie icon on the upper left corner, and click on “Home Videos.”
You'll see your video there. For the next step, make sure your phone is plugged into your computer. Simply drag your video onto the iPhone icon.
In the middle bar on the top, you will see that the video is automatically syncing to your iPhone.
Once it syncs, open Apple’s “Videos” app on your phone and you should see your video! Mine is right there to the left of the Incredibles.
