is a video compression format for progressive or interlaced resolutions from QCIF (180 x 144) to HDTV (1920 x 1080).
Released in 2008, Dirac can provide data rate savings and quality superior to MPEG2 and MPEG4.
Both lossy and lossless compression modes are supported.
This format can be used in various containers such as Ogg, Matroska and AVI. The Dirac codec uses motion compensation, wavelets and arithmetic coding.
The input supported by the decoder is YUV/420 only; other types of input such as 411, 422 or 444, will be output without the decoded u/v planes.
