The iPod is a very popular device due its support for a wide range of multimedia items, and users often encode their preferred videos to iPod-compatible formats whenever they want to enjoy their clips when on the go.
One will be able to rip their DVDs to iPod, or to convert regular clips to other formats and adjust the video size or aspect ratio to fit the iPod's settings.
Some iPod converters can also be used to split or cut one's files into smaller parts, while they will also allow video joining and merging.
Even if users will have the possibility to adjust the video's parameters, inexperienced ones should not modify the default settings as they might affects the video's quality.
