Recently, I started taking videos using my handphone (PDA Phone). Videos taken using the phone defaults to MP4 format. However, I faced a problem of not being able to use Windows MovieMaker to edit and join the videos together.
I downloaded a few free video editor programs but most of them do not support MP4 format either. Finally, I came across Pazera Free MP4 to AVI converter which allows you to convert to MPEG-1 - which can then be used in Windows Movie Maker.
