Heres what I use for my daily transcoding of a show into XviD (version
1.0.2):
Enable Myth cutlist? [Yes]
Enable noise reduction (slower, but better results)? [Yes] No
Enable deinterlacing? [Yes] No
Crop broadcast overscan (2% border)? [Yes]
Audio bitrate? [128] 96
Variable bitrate video? [Yes]
Multi-pass (slower, but better quality)? [No]
VBR quality/quantisation (1-31)? [6] 4
Width? [624] 320
Height? [240]
With commercials edited out it takes about 1 1/2 hours on my P4 1.6Ghz
and the file sizes are around 80-100meg.
As you might have guessed, quality isn't that important to me, although
I think the files are surprisingly watchable.
