If you have some video files saved in your local hard drive, you may want to play them on your iPhone, iPad or iPod devices. If they are iTunes-, iPad-, iPhone-, or iPod-compatible video files, you can easily transfer them to your device with the sync of iTunes.
Tips: In case the video files cannot be imported into iTunes library, or they are iTunes-, iPad-, iPhone-, or iPod-incompatible video files, you may download Video Converter App to help you get them transferred to your device and converted there with ease.
