How do I download videos on iphone?

Depends on the video format and what you want to do with the video.

Easiest:
Download the video to a computer, pull the video into iTunes, sync phone and computer through iTunes.

If video is available at the iTunes store, connect phone to iTunes (assuming you have a valid account) and get or buy the video.

There may be other ways, but without knowing the source of the video to be downloaded or the file type, we don't know if other steps might be needed to make the video readable by the iPhone.
