Hallo > yuvscaler -O SIZE_720x480 | \ If you create a DVD you could use -O DVD too.

Of couse you could use a higer (till 4) quality factor. But did the original video had 5000kBit average bitrate or maximal bitrate ? > > If you want to change the framerate of a stream, I'd say that you > > deinterlce it, if it is interlaced in the first step. > That's seems to have fixed the jerky-ness - it's now very smooth. You loose a bit quality because of the deinterlacing, but as long yuvfps is only coying frames it is a reliable way to get a smoth picture. > > BTW: 24000:1001 is also a valid NTSC framerate you could choose. > If I used this rate, would my DVD player have to do a 3:2 pulldown? Right, but I gess DVD's from film often also have 24FPS, If you encode at 24FPS you should add the -p|--3-2-pulldown, so the player does a 3:2 pulldown. > Reading up on my DVD player, it's the only progressive scan player out > there without a 3:2 pulldown. It's a Pioneer DV-434. Two Pioneer's at home but bot other models ;) > Also, www.dvdrhelp.com says that my dvd player supports divx.

The original Dolby Digital (2 channel) sound was preserved. There the -q option might help. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.net email is sponsored by: Perforce Software.
