There is nothing at the moment but it is a great suggestion :)

Yeah, I'm sure Canopus HQ is a much better codec. I have not done any tests, so this is my non-researched opinion.
Even at 28Mbps it is still not bad considering how much Uncompressed HD eats. Also ProRes422 supports 10bit, CHQ only does 8bit.

The ProRes422 codec kicks in at about 28Mbps at highest compression and grabs more bandwidth at it's HQ setting. It may be good but it seems high to me.

There is a huge market for this, especially mobile editing via a laptop.
But doesn't the AJA IO use the ProRes422 codec? It is a low bit rate VBR codec, similar to Canopus HQ.

Pegasus implications
According to "Studio Daily" when reporting on the GV Pegasus board here :
These days it seems that lots of manufacturers are offering a way to capture a still frame from moving video. The challenge is finding one that can do it in real time and with the proper amount of sophisticated compression to save space and preserve image quality. (HD video is very data-intensive, requiring lots of storage.) Otherwise you'll find yourself chained to the computer for hours, when you could be done in minutes.
"The Grass Valley HQ software codec only recently became available on a silicon chip"
This does raise the prospect of new editing boards ala Storm and Rex but with the "HQ Software Chip" onboard instead of a DV chip. AJA have done that with their IO HD and and the FCP HD codec. The problem with the IO is that the minimum data rate is about 10 X DV, even with compression. Whats more you can't connect a firewire VCR at the same time cause the IO monopolises the bus! Correct me if I am wrong but I presume the Canopus HQ codec can be much more efficient.
Lets see....less storage space, HD, more computing power, more realtime effects, full control of all devices. Seems an interesting prospect!
