Note: If the file you need to split is an mpeg, see my other article on splitting MPEG files.
To split avis, we will be using the extremely popular and excellent VirtualDub which is totally free but more capable than many video editing programs costing hundreds of dollars. You can waste a lot of time and money searching for a satisfying video editing program, when all you may really need is VirtualDub. Note however, that VirtualDub is mainly for working with avi files - not mpeg files.
