I have a p4 1.8 (not o'clocked) 256 pc21oo..
using Vdub 1.5.1 P4 version..
Nic's XviD 2/16/o3 version..
motion - 6
quantization type - H.263
FourCC Xvid
VHQ - 1
Max I - 3oo
min I - 1
check is lm, chroma motion, quarterpel
b frames - 3/15o/1oo
DX5o check'd

everything else is default expt i uncheck SSE2 in force optimizations cause it seems to crash..

ok the problem is why am i only getting between 4-12 fps..
here is how my avisyth script looks also..

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\MPEG2Decoder.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Convolution3DYV12.dll")
mpeg2source("D:\ENTER_THE_DRAGON_16X9_LB_NA\VIDEO_TS\enter.d2v")
Convolution3d(preset="movieHQ")
BicubicResize(512,256)

I posted here cause i am slightly a n00b, was going to post in XviD but really didn't know what forum to post in correctly.. thx..

Hi-

Scared to post in the XviD forum, eh? I can't say that I blame you. Convolution3d slows you down (I might suggest the YV12 version of FluxSmooth as a faster alternative). And VHQ slows you down a lot also. However, it makes a noticeable improvement in the quality, so I use it anyway. You might do a short test without those 2, and I think you'll see the encoding speed jump.

Also, the H.263 Matrix softens the video anyway so, personally, I wouldn't use it together with C3D. I might use it with the MPEG matrix. But that's just me. Maybe just use a light temporal smoother instead (and the encoding will speed up as a side benefit). I don't use Luma Masking either. Make your own tests to be sure.
