Twibright Luminaplex and Hyperluma 2 are two algorithms and an example implementation developed to encode (chroma subsample) Y'CbCr video at 4:2:0 and 4:2:2 scheme with higher quality than was currently possible. Ordinary encoding introduces errors, while Luminaplex eliminates virtually all error by finding the values of minimum error. It is published as a prior art to prevent coverage by a software patent.
3gp converter is a GUI that uses ffmpeg to convert video files in the 3gp format, which is used by mobile phones. ffmpeg must be compiled with AMR audio-codec support for this to work. Custom encoding parameters can be set for video streams, such as resolution, bitrate, framerate, used codec (h263, mpeg4), and one or two pass encoding. For audio streams, bitrate, samplerate (AAC only), and audio codec (amr_nb, AAC) can be chosen.
VLC media player is a multimedia player, framework, streamer, and encoder. It can play inputs like files, network streams, DVDs, audio CDs, Blu-Rays, capture devices, and screens. It can play most audio and video codecs and formats (MPEG 1/2/4, H264, VC-1, DivX, WMV, Vorbis, AC3, AAC, MKV, etc.), but can also be used to convert to different formats and/or send streams through the network.
Twibright Pitchotron analyzes any MP3 into the semitones that are being played, displayed in a scrolling coloured graph on a video. It aids musical transcription. It includes coloured piano key stickers that enable accompanying arbitrary music and improvising even to musical analphabets.
