Speed; while not as fast as Huffyuv , encoding speed is comparable to many other lossless video codecs, although decoding speed may be slower. Recent versions also support parallelizing on multi-processor systems.
Color-space support; color-space conversions can cause rounding errors, introducing data loss, contrary to the ideal of lossless video compression. Lagarith attempts to avoid this problem by supporting YV12 , YUY2 , RGB , and RGBA colorspaces.
Keyframes ; disallowing inter-prediction means that each frame can be separately decoded. This makes cutting, joining and seeking much easier.
These three things, as well as being more efficient than Huffyuv make it a codec useful for the video editing stage.
