What is MP4?

[Calvados]

I downloaded a video but can't watch it now cos it says I need MP4. How can I get that?

MP4 or MPEG-4 is a video and audio compression type. Used in things such as Camera phones to store video clips, as *.3gp files.

MPEG-4 is also the video standard decoded by the XViD / DivX codecs. So it may vary depending on the type of clip you have.

XViD Codec can be downloaded Here
Check out Apple's site on MPEG-4 if this is a cell phone clip too, here.

If you want a video player that will play just about any format you can think of, then get vlc (it's free):
