Media Players
Most modern media players can play MP4 formats, however finding converting tools for MP4 is not easy - Daniel K. Schneider 13:44, 18 June 2007 (MEST).
- Commercial (usually free)
- QuickTime / iTunes (Apple Inc.)
- RealPlayer
- Zune, the new Microsoft digital audio player, online music store, and client software (nov 2006)
- Winamp, used to be or still is a most popular MP3 player. (Wikipedia entry)
- Free and open source
- FFMpeg (Wikipedia entry) is a collection of free software hat can record, convert and stream digital audio and video.
- Mplayer (Wikipedia entry). Multiplatform.
- xine is a multimedia playback engine for Unix-like operating systems that supports almost any format. (Wikipedia entry).
Video editing software
- See video editing
Encoders and Converters
Finding e.g. a simple MP4 to MPEG-2 converter is a real pain, since searching the Internet leads to confusing commercial index web sites.
- MediaCoder Free
- Encoder (a sister project of MPlayer).
- SUPER, Simplified Universal Player Encoder & Renderer. (see also the Wikipedia article).

Hints
MP4 videos from a Nokia N73 to YouTube
YouTube only supports .WMV, .AVI, .MOV, and .MPG file formats (other details, i.e. codecs supported are not clear to me).
I used the free SUPER Program (see link above).
- Output = WMV
- Output Video codec = VMV8 or MS-MPEG3-v2 (for WMV7 I got an error)
- Audio Codec = MP3
- Video/Audio: I used the defaults
Note: Super will by default write the output file to the root of the c:\ directory. Right-click anywhere in the Window to access the menu (you can fix output location there).
