Lagarith
From Wikipedia, the free encyclopedia
Lagarith is an open source lossless video codec written by Ben Greenwood. It was designed and written with a few aims in mind:
- 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.
