Compatible Video Formats
The iPad natively supports many of the common video formats used today, including H.264, MP4, M4V, MOV, MPEG-4 and M-JPEG. By default, these play in the iPad's Videos app. The iPad does have limitations within these formats. For example, H.264 videos are limited to 1080 pixels and 30 frames per second. MPEG-4 videos are limited to 2.5 Mbps and 640 by 380 pixel resolution at 30 frames per second. Videos exceeding these limits may not play correctly on an iPad, or may not play at all. Although the iPad does support stereo sound, you will need headphones or external speakers to hear it. The built-in speaker provides only mono playback.
Incompatible Videos
The iPad does not support AVI, Flash (FLV) or Windows (WMV) video file formats. If you have a video in these formats, you will need to convert it to a compatible format before you can play it on an iPad. If your video is in a compatible format, but the size or speed is incompatible, you can convert it in iTunes. After dragging a video into the Movies section of iTunes, just select the video and select "Create New Version" from the File menu. You can then specify an "iPad version" of the video.
Additional Video Apps
If there is a format not supported natively by the iPad, a third-party app available from the iPad's App Store may do the job. For example, iMedia Player is free ad-supported app that can play AVI, WMV and AVI videos without the need to convert them. Video Downloader is another free app that plays a wide range of formats, including WMV, FLV, DVX and MPG. It also gives you the ability to download videos to the iPad. Media Player Pro also plays a wide variety of video formats and includes support for high definition video.
