VfW configuration dialog of Lagarith video codec

Lagarith is an open source lossless video codec written by Ben Greenwood.[1] It was designed and written with a few aims in mind:

while not as fast as Huffyuv, it still outperforms most other lossless video codecs when it comes to encoding times,[2][3] 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.
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 at compression than Huffyuv, make it a codec useful for the video editing stage.
