How do you transfer videos from your computer onto your iphone?

Use Itunes, download the file in mp4 and drag it to your ipod name bar on the left side on itunes

If the video is not in mp4 format, you will have to convert the footage. I prefer using dvdvideosoft.com's video converter. They have no viruses or anything.

Using itunes, but notice the video format, because iphone or ipad or ipod only can support a few formats, like mp4.
if the videos of yours are rmvb, avi or whatever, you need to convert the format first.
you can choose zamzar (online free converter) or istonsoft video converter (free desktop converter)
