I was trying to encode gladiator to 1 cd following the below setting give by keopi, i coundnt find lumafilter!!!!

If it's hard to compress and you're heading for 1CD you should use 2 bframes and a threshold of 255 SysKin doesn't like that high threshold, but for 1CD rips it really helps a lot. I didn't get my hands on that particular DVD yet so I don't know how much detail and noise is in there, but I'd recommand

Avisynth 2.5x, YV12
- LumaFilter()
- Convolution3d(preset="movieHQ") # only if there's little noise,
# sometimes preset="movieLQ" is necessary - movieHQ doesn't harm
# quality at least
- UnFilter(-5,-5) # for very little oversharped movies, else more
- UnDot()
- LanczosResize()(+bilinear resize for credits range)

If you still don't hit desired low bitrate you may try Bicubic Resize(x,y,0,0.5) instead of Lanczos.

VDubMod for encoding in YV12

If the movie has plenty details, try qpel. ChromaME is mandatory of course, it's just slowing down the encoding a little but usually helps where you else would've gotten blocks since it takes colour information into account as well.

...so nobody can complain I'd hide my favorite settings.

It comes together with MarcFD's version of MPEG2Dec3.

I wanted to try out Koepi's suggested settings as well (Couldn't find Lumafilter at first either) but as I'm new to Avisynth (2.5) I'm having a problem framserving the .avs to Vdub (1.5.2 P4). The colours are messed up but I presume this is somthing to do with the YV12, although I thought that Xvid would convert this after encoding.

@Wam7: Some VFW codecs have bugs, and delivers swapped UV-channels - there is a fixed version of Morgan MJPEG - otherwise use swapUV().

Thanks for that sh0dan. I did use Morgan MJpeg 3.0.0.9 to do the capture using YUY2. Is this the cause for the problem and will using swapUV() in the last line of my script fix this? (I'm sorry if this thread isn't probably the best place to ask)

edit: No need to answer that as I've found some info searching for Morgan & YV12

AVISource("file.avi",pixel_type="yuy2")
converttoyv12(interlaced=true)

This did the trick. Thanks again sh0dan
