So it looks like they have dedicated hardware for en/transcoding, and they're not using the GPU shaders/processors to do the job. It's not like general purpose computing with the GPU.
I sure hope that they make the API calls they used available to the companies that package encoders in their stuff. ATI worked with my NLE vendor at one point and the GPU is now heavily used directly by the app for video rendering via DirectX. It is a distinct advantage over other editors in the way it renders and can playback unrendered video in real-time. Since many editors can now edit native MPEG, there is the potential to set a DVD/HD-DVD target quality in advance and the GPU would be doing the encodes in real-time. When you go to create the DVD (inline authoring is also available on some editors), it would be straight to disc without waiting for the 'encode' phase.
Unfortunately the speedup is only with ATI's Xcode. Put it in Adobe After Effects and Premiere and I will buy the cards for work where we do a lot of video encoding. Until then, it is just something that is interesting to see, but not of much use (for me). Still, ATI, you have caught my eye...
