Well, I just encoded on a couple different platforms the clip that
was uploaded to me and I can't seem to reproduce the artifacting.
Tried a Intel based system (BSD) and G4/Altivec (Powerbook) and
it looks good. It does look like centering with y4mshift would
be a good thing - the frame has a lot of junk on the left edge but
none on the right. 'y4mshift' with -n -4 and a border with
-b 4,60,312,360" would work very well. Doing that dropped the
bitrate from 1330 to 952 Kb/s on the Pentium-3 system and from
1524 to 1096 Kb/s on the G4/Altivec system.
Cheers,
