NVISION 2008: Nvidia and Pegasys have announced CUDA support for TMPGEnc 4.0 Xpress and it delivers pretty big performance gains.

FOUR HUNDRED AND FOURTY SIX PERCENT

And Tmpeg was one of the things Intel was poster childing as having SSE4.1 support

back last November.

YAY

I hope to see more CUDA support in more apps!

Excited by the prospects of massive video encoding speedups?

I am.

Specially if CUDA would allow me to NOT having to wait overnight for an Adobe Premiere project to encode to a Video file...

I can't wait to see how Adobe is going to implement CUDA on their programs (I do hope they do it on Premiere Elements).

Come on AMD. I brought this card because it's bloody awesome, now I want some more uses for it.

AMD may be ahead as far as hardware goes for now, but stuff like this is what's going to keep Nvidia on top, in my mind anyway. AMD is lagging far behind in the GPGPU segment at the moment.

Careful. The entire purpose of TMPGenc is to be really really damned good.

I can make it 446 percent faster by making it really, really bad.

Need some comparative SNR figures for what must be an entirely new encoder.

Not necessarily - it could be the same encoding algorithm using new code that is optimised for the GPU, so the result would be mathematically identical and hence indistinguishable from CPU encoded video.

Just imagine, if CUDA was based on assembly language rather than C, the speed advantage would be 1337%.

Or perhaps OVER 9000!!!

Or not.

the BadaBoom test on Anandtech didn't show very large improvement in encoding speed from q6600 to 8800GT (or was it 9800GTX, i remember it's a G92 chip)
so IMHO it'd be best to leave Geforce to Fold while use CPU to encode.

WARNING: TMPGEnc doesn't use CUDA for ENCODING but just for FILTERING.
I've downloaded the trial version and used it to transcode an mpg video to divx: progress window shows CPU and GPU usage and while just trascoding it was 100% and 0%. So CUDA will speedup as much as nothing transcoding with TMPGEnc.

Otherwise if you apply some sort of filtering to the video you are processing (for example noise reduction or contrast change) then GPU load goes up.
So if you think this product will speedup your video conversions you are on the wrong road.
