ATI Stream technology with CF? at DVinfo.net

David, does this tech have any future for CF users? Seems they are talking to quite a number of ISV's on this. Is CF one of them?

DailyTech - ATI Stream Technology Cuts Video Transcoding Time in Half

We have not had any discussions with ATI about this yet. I suspect their first priority is accelerating distribution codecs that are typically asymmetric - like MPEG, AVCHD, and h.264.

Wish our video productions were as symmetric as CF...instead of 20x1...and why is CF symmetric if my renders take so long...? :)

The assymetric part is called Adobe. We have thought of completely bypassing Adobe render engine and do have a playback mode that plays into a file, we could to that faster than real-time in many cases, but there quality reasons not to do this. It would certain help point out it is Adobe part that slows us down. However, the 20x1 number points to something more wrong, as we should be seeing 5x1 with Adobe. Working with Adobe to see where our 15x went.

Guess we live in an asymmetric world. That would explain why my Fridays and Mondays are at the bottom of the curve...
