  <title>Video Codec based on wavelets</title>

  <description>Dirac is an open source video codec.

​

It uses a traditional hybrid video codec architecture, but with the

wavelet transform instead of the usual block transforms. Motion

compensation uses overlapped blocks to reduce block artefacts that

would upset the transform coding stage.

​

Dirac can code just about any size of video, from streaming up to HD

and beyond, although certain presets are defined for different

applications and standards. These cover the parameters that need to

be set for the encoder to work, such as block sizes and temporal

prediction structures, which must otherwise be set by hand.</description>
