| Which video encoders support the SSE4 instruction set? I currently have tmpgenc plus and the main encoder 1.5 and I know the tmpgenc version I have doesn't but I am not sure about the main encoder. |

| DivX 6.6 codec and greater carry instruction set for SSE4. If your computer details are up to date (Athlon 2800+), you will not be able to take advantage of it. |

| I am looking for an mpeg 2 encoder that will support these. I have one the new intel quad core cpu's that supports sse4. I have heard that encoders that can take advantage of these instructions are much faster. I have and encoder for doing avi's but I was wanting one for encoding to dvd format that supported this. |

| I am unaware of any MPEG2 encoders that support SSE4.
MPEG2 is slowly dieing out, I doubt there will be much active development for this |

| "are much faster" .. yes you can have gains up to 200%, in some specific routines and specially chosen circumstances.
More normally these things get you at best 10% speed increase, the rest is down to a faster CPU speed, faster memory and other factors. These instructions seem to help in motion estimation (or GMC, warp points in divx/xvid). A GPCPU would work better, with native CUDA code..increase of 1000%? sound good? |
