Resolution, IBC and 4K +

[Blair S. Paulsen]

Perhaps the Davids cashed out sufficiently on the GoPro deal that a different licensing scheme for CineForm with lower costs makes sense.
Its my favorite RGB codec for 4K in terms of file size/quality.

I am a big fan of JP2K (JPEG 2000) which, AFAIK, is the underlying codec for RedCode and the DCI (Digital Cinema Initiative) spec used for distributing feature films to the digital projector in your local theater. At one point there was talk of a version of RedCode that would carry an RGB image rather than the Bayer pattern data encased in the r3d files using current RedCode. I have blathered on about how much I would love to see such a codec available for use as a post enabling mezzanine codec in the 100-250MB/sec range for 4K. Still think it would be a great tool, BTW, but perhaps a lower bit rate version, 20-50MB/sec @4K, for mastering and transit to distributors would do more good.

IIRC the reason JP2K has not been utilized more is due to demanding encoding requirements that require beefy hardware and/or lengthy renders. Is that still a major hurdle in 2012? I know with RedCode the decoding is non-trivial as well so perhaps there are client side issues as well. If Mike M., Graeme or some other well informed person can explain why JP2K is a poor choice for applications beyond its current implementations then I'll shut up. Is there a more modern wavelet codec out there? Sure would be nice to have a codec that offered "extraction layers" so one could master at a good quality bit rate and from the same file you could extract a lower quality version suitable for distribution rather than having to author multiple versions.

An alternative to JPEG 2000 is JPEG XR, which has the same or better quality, but better performance (and some other additional features). http://en.wikipedia.org/wiki/JPEG_XR
