MediaCoder is a free transcoder that will quickly convert any audio or video file into your format of choice. Supported video formats include H.264, XviD, DivX, MPEG-1/2/4, Flash, Theora, Dirac, H.263, RealVideo, WMV and MJPEG, and the program can handle most containers: AVI, MPEG PS, MPEG TS, Matroska, MP4, PMP, RealMedia, and ASF. MTS/AVCHD, QuickTime and OGM are supported for input only.
And on the audio side, the program can work with all the audio files you’d expect, and many you wouldn’t: MP3, Ogg Vorbis, LC-AAC, HE-AAC 1/2, AC-3, MPEG Audio L2, MusePack, Speex, AMR, WMA, ADPCM, mp3Pro (input only), FLAC, WavPack, Monkey’s Audio, OptimFrog, ALAC, TTA and PCM.
[advt]The program is absolutely packed with options to help you configure every step of the conversion process, and that can make it a little tricky to use, at least at first – expect to spend a while learning your way around. Once you’ve mastered the basics it’s quite straightforward, though, and strong multi-threading support ensures your files will be converted with the maximum possible speed.
