From what I understand this whole project is being captured to HuffYUV lossless video and that, because of the minimal compression, storage space is becoming a factor. I was just reading about this new lossless video codec that supports multi-processor setups (unlike HuffYUV) so that it is faster on render machines and has higher compression than HuffYUV. I wasn't sure if you gents had heard of it, and as it sounds pretty good, so I thought that I would give it a mention here.

Lagarith Lossless Video Codec

Sorry if I'm repeating old information.
