IPod Video A General Overview-Part2
......
The second format is MPEG-4 video. This type supports up to up to 2,500 kilobytes per second, and a picture size of 480 pixels wide by 480 pixels high. This resolution is three times as many pixels as the iPod is able to display. This means the iPod will have to shrink the file in order to display it on the screen. MPEG-4 files are typically larger resulting in less storage space for additional songs and movies. Audio encoding and file extensions are the same as H.264 video specifications.
While the H.264 offers higher quality video and smaller file size, it takes a longer time to covert the file to a compatible iPod video. Because of the higher pixel size, MPEG-4 formats are ideal if you plan to watch videos on your TV.
There are several ways to determine if a video can be played on your iPod. Open iTunes with your iPod connected and drop the file into your iPod library. If the file is copied, then it is compatible. To do this, you will have to make sure that you have selected to manually manage songs and playlists in the iPod tab of your iTunes preferences. Another way to test compatibility is to add the video to the iTunes library. Once it has been added, right click the video and select “Convert selection to iPod”. If it is already compatible, iTunes will give you a message saying so. If it is not compatible, it will be converted into a compatible format.
You can add videos to your iPod from any computer that has iTunes installed. If your iPod was originally formatted for PC you can add videos from Mac or PC. If your iPod was formatted for Mac you can only add videos from another Mac computer. If you have QuickTime Pro you can easily convert movies and videos into a format that is compatible with your iPod.
The iPod video includes a few other amenities in addition to its video capabilities: a screen lock to keep sensitive information private, a world clock displaying the time in major world cities, and a stopwatch.
