Pazera’s Software Free Audio Video Pack is a collection of video and audio converters that help convert between a wide variety of common audio and video formats. The package also includes applications that allows you to extract audio tracks from CD images based on the CUE sheets, as well as an audio extractor that lets you take just the audio from a video file.
Supported video outputs include AVI, MPEG, MP4, MOV, WMV, FLV, MKV, M4V and 3GP and audio formats include MP3, WMA, OGG, WAV, AAC, AC3, and FLAC. Many of the programs act as a front-end for FFmpeg.
