Transcode – transcodes various video, audio, and container formats

Transcode is a suite of tools, all of which are command line utilities, for transcoding various video, audio, and container formats, running on a platform that supports shared libraries and threads. Decoding and encoding is done by loaded modules that are responsible for feeding transcode with raw video/audio streams (import modules) and encoding the frames (export modules).

It includes a variety of video and audio filters, including (but not limited to) video de-interlacing, audio resampling, framerate conversion, different video resizing algorithms, smoothing, sharpening, denoisifying, and cutting.

It’s modular concept is intended to provide flexibility and easy user extensibility to include other video/audio codecs or filetypes.
