I continue to make progress in creating my home video library. This
morning I stated to play around with some of my kids' cartoons.
Surprisingly, the video quality is awful - you can see the tiling
clearly and many of the edges have visible artifacts.
I'm playing with the following command to encode the tapes:
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=500 -oac mp3lame -lameopts
vbr=3 -o movie3.avi
which produces acceptable live action movies from tapes and DVDs (my
definition of "acceptable" is suitable for viewing on a 9" portable
TV.) I do a bit of clipping and rescaling on the DVDs but that's not
really relevant here.
I remember reading somewhere that sharp color transitions consume a lot
of bandwith. Cartoons have a lot of those.
Is this right? Any codecs suitable for cartoons? Any help is greatly
appreciated. I really don't want to use a bitrate greater than 500 if I
can at all help it, both for size and network bandwith considerations.
