5-Fold Increase in Video Encoding with OpenCL-like Technology
NVidia and Nero announced yesterday that a recent update to the Nero Movie it software application for Windows reduces video encoding time by up to five times by utilizing NVIDIA's CUDA architecture. They specifically describe the encoding of HD video for an iPod going from "hours to mere minutes" when the application is used in conjunction with a supported NVIDIA graphics card.
CUDA is NVIDIA's parallel computing architecture that harnesses the power of their graphics card GPUs. This allows developers to leverage the parallel processing power that is otherwise being unused within these graphics cards.
OpenCL is an open standard that was established in collaboration with AMD, Intel and NVIDIA and was ratified in December. Apple is expected to release Mac OS X Snow Leopard later this year, and we should hear more details at WWDC in June.

By using CUDA technology to tap the massively parallel processing power of NVIDIA GPUs, Nero Move it converts videos in a fraction of the usual time, reducing the length of time to perform such tasks as customizing an HD video for an iPod, from hours to mere minutes.
While the announcement is not directly related to Apple, the harnessing of this GPU power is the cornerstone of OpenCL which will be featured in Mac OS X Snow Leopard.OpenCL is an open standard that was established in collaboration with AMD, Intel and NVIDIA and was ratified in December.

That's what makes OpenCL great. If applied to a task it's particularly well-suited to, such as video/audio encoding, it speeds the task up enormously. I can only dream about what this will enable in iTunes... imagine transcoding an iTunes library in ALAC to AAC, that has about 8000 songs in it. Today, this takes about 5 hours. With OpenCL, only 30 minutes will be required. :D

So will this work in a VM enviorment or under boot camp???

I'm sure Adobe will use this as a way to get people to upgrade to the next CS in a year or so.

Sounds great! Five fold says alot and I wonder if Apple will use this anytime soon. Also, how will the battery be affected? I figure we see this technology end of this year or next

Hmmm ... Better than Handbrake? :)
Aaahhh . . . yeah! This is not an ordinary "software vs. software" situation. What they are talking about is yes, software, but software that is using a graphics card GPU to do most of the heavy lifting for encoding (usually a very intensive CPU task) So it is not a simple as asking "you mean faster than software X?" but rather "when will OTHER software start using this technology?"

Of course Apple's going to use this - it says so on Apple's Snow Leopard page.

We'll soon see how much Apple has integrated OpenCL power into the OS and it's applications also. Can't knock a 5x speed increase - I'd imagine we'll see more and more benefits as we move towards Snow Leopard's release.

Yes, in Boot Camp, provided the drivers to take advantage of it are available. No, in a VM environment.
Well, it could be made to work in a VM, but that would require support from the VM software maker and probably the GPU vendor as well. I wouldn't look for it out of the gate, but it might come eventually.
