I use to encode using sbc, fit on 1 cd, with resize filter and deinterlace if needed.

I get too blurry divx.

Thats the standard vcf i use for the second pass...

VirtualDub.video.SetDivX(700,10);
VirtualDub.video.SetQualityControl(1,0,0,0);
VirtualDub.video.SetMotionDetection(8,10,300,300);
VirtualDub.video.SetCrispness(30,0);
VirtualDub.video.SpaceKF(24);
VirtualDub.video.InternalSCD(100);
VirtualDub.video.SetMinKBPS(360);
VirtualDub.video.SetCurveFile("");
VirtualDub.video.SetCurveMcFactor(20);
VirtualDub.video.SetCurveCompression(15,25,3);
VirtualDub.video.SetCurveFilter(270,2500);
VirtualDub.video.SetCurveCredits(0,250);
VirtualDub.video.SetLumaCorrectionAmp(1,10,30);
VirtualDub.video.SetCurveRedist(1);
VirtualDub.video.SetCompLevelsMain(2,8);
VirtualDub.video.SetCompLevelK(2);
VirtualDub.video.SetBitsReservoir(0,35,30,70,45,0);
VirtualDub.video.SetLowBrCorrection(1,1);

Plz any help?
shall i use more filters ?
are those values correct ?

Without knowing exactly what you have tried before I have some general hints for making sharper picture:

Check the resize. To get the sharpest resize you should use bicubic a=-1.00,
Add a 'sharpen' filter. To get the sharpest effect this should be done after the resize.
Increase the bitrate. First thing that goes away when the bitrate is too low is sharpness.
Increase the resolution. This means that you have more pixels to make a sharper picture with. This must be accompanied by an increase of bitrate as the codec will need more bits to encode the larger picture.

If you're encoding an NTSC source, make sure you drop the framerate down from 29.9 to 23.9 fps too. Less frames = more bits per frame.
