One codec i'm curious about is SheerVideo:
http://www.bitjazz.com/en/products/sheervideo/
From the site:

With its direct lossless support for all professional pixel formats
for digitized film & synthetic imagery (RGB[A]) and video (Y'CbCr[A]),
both with and without alpha, in high (10-bit) and standard (8-bit)
precision, full-range and video-range, uniformly sampled (4:4:4[:4])
and 1:2 chroma-subsampled (4:2:2[:4]); at any resolution, including HD
(high definition) and SD (standard definition), NTSC, PAL, & SECAM;
4:3 & 16:9, progressive and interlaced, SheerVideo is the most
versatile codec in the world. Support for 16-bit channels is coming
soon too, to satisfy the needs of the most demanding expert.

It's $100 a license if you buy over two. It sounds great, I'll likely
test it. There's also a free read only codec. However, I've never come
across it in professional settings, which always makes me nervous
regarding it's longevity.
