1. Languages: English
2. Compatibility: (they say only that SUPER © is compatible with most Windows® platforms)
3. License: Freeware
4. Description: SUPER © Simplified Universal Player Encoder & Renderer. A GUI to FFmpeg, MEncoder, MPlayer, x264, MusePack, Monkey's audio, Shorten audio, TAK audio, True audio, WavPack, the libavcodec library & the theora/vorbis RealProducer's plugIn. If you need a simple, yet very efficient tool to convert (encode) or play any Multimedia file, without reading manuals or spending long hours training, then SUPER © is all you need. It is a Multimedia Encoder and a Multimedia Player, easy-to-use with 1 simple click.
5. Opinion: I use it to convert every video or audio format or to extract only audio or only video-without-sound from video files, changing some parameters as video size.
