Almost every cell phone on the market has the ability to capture video. The common format that cell phones store video as is the ".3gp" file extension. 3GP video files are generally only watchable on cell phones and select media players. They are almost never recognized by other programs, such as video-editing software packages.
If you have captured footage from your cell phone, would like to be able to view or edit it on your PC, you can convert the 3GP video file into a more recognizable file extension like AVI.
