Hello,

I have been tranfering some DV recording to VCD and SVCD, and I am
a bit surprised by the result. I first created the VCD, with a non-
standard bitrate of 2500, and I was surprised how good it looked
(played with a DVD player on a TV). Then I created the SVCD (standard
settings). expecting it to be even better, but in fact it contained a
lot of artifacts (the wringling on large surfaces around borders, I
don't know the slang for)

Now, I realize the SVCD bitrate has been a bit lower than the VCD bitrate
I used, but only slightly. Maybe the VCD is smoother because I used
yuvdenoise in the chain? Or maybe because the VCD resolution is a lot
lower, while this doesn't really matter on a TV set? Or maybe I just did
something wrong when creating the SVCD?

I send you the settings I used. Any suggestions will be greatly
appreciated!

Maarten
