<strong>Part I. Understanding the formats compatible with iPad</strong> You know that 9.7-inch high-resolution screen makes iPad perfect for watching video, but that doesn't mean that every type of video file will play on your iPad. The iPad supported video formats are: H.264 video (up to 720p, 30 frames per second; main profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats); MPEG-4 video (up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, simple profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats). <strong>Part II. Converting Standard Digital Video and HD Video Content</strong> Standard Digital Video Content refers to the various types of digital content that can be stored on a computer, such as that obtained from web sites and already pre-extracted from DVDs into other non-iPad-ready formats. HD Video Content means high definition video. The HD video generally refers to any video system of higher resolution than standard-definition video, most of them are at display resolutions of 1280×720 (720p) or 1920×1080 (1080i or 1080p), and obtained from AVCHD and other HD digital camcorder. There are many free tools for iPad video conversion on Mac, like <a href=http://www.isquint.org/>iSquint</a>, <a href=http://www.visualhub.net/>VisualHub</a>, <a href=http://www.squared5.com/>MPEG Streamclip</a>, etc. But iSquint and VisualHub have been discontinued and are no longer for sale, while MPEG Streamclip cannot convert HD video content. Maybe you can convert HD video from most digital camcorders through Apple's iMovie HD application included in iLife '06 or above. But iMovie does not provide any additional default presets for higher-resolution iPad, also the conversion times will be quite slow as it uses the underlying Quicktime engine. So far the best option for HD and SD video conversion for iPad maybe <a href=http://www.ifunia.com/video-to-ipad-converter-mac.html>iPad Video Converter</a>, still from iFunia Corp.
