ProRes 4444 is lossy though, which BitJazz and Animation are not. It remains to see how well ProRes 4444 handles color space conversions. Apple are well known for their gamma issues in QuickTime. Animation and Photo JPEG are still very g

Lossless comparison - Hydrogenaudio Knowledgebase
The lossless comparison page aims to gather information about lossless codecs available so users can make an informed decision as to what lossless codec to choose for their needs. Introduction Given the enormous number of lossless audio compressor choices available, it is a very difficult task to choose the one most suited for each person's needs. Some people take into consideration only compressi
Lagarith Lossless Video Codec
Lagarith is a lossless video codec intended for editing and archiving. Lagarith offers better compression than codecs like Huffyuv, Alparysoft, and CorePNG.

Lagarith is able to operate in several colorspaces - RGB24, RGB32, RGBA, YUY2, and YV12. For D
