How do you put your own videos on iTunes?

[Húrin]

I have videos on my computer that I want to put onto iTunes so I can then put them on my iPod although it doesn't seem to work. I'm using the same method that I do to get music on there but the videos don't show up.

I'm clueless on these sort of things so help would be very much appreciated. D:

it would help if it were, you know, a movie.

Also try making sure the video is MP4 or MOV
