View Full Version : Dvd2svcd, Movies are good but TV prog DVD's end up not so good.

I've been using dvd2svcd (ver. 1.1.2 build 1 at the moment) for a while now and all the movies I've done are perfect, almost as good as the originals. Recently I've got a couple of dvd's of tv programmes - Hitchhikers guide to the Galaxy and Absolutely Fabulous amongst others. I've done tests using all different settings, keep interlaced, blendfield etc but they all look a bit dodgy on moving edges, even on backgrounds there is a lot of quantising(?)effect. A couple of concert video's I've done using blendfield don't look too bad but I'm not happy with the results of the tv shows (they're all PAL). Anyone else having these problems or has any suggestions?

thanks

to your problem: deinterlaced content will never have the same quality than content that was progressive from the beginning. but that is how it is... afaik there's not way to change it!

"even on backgrounds there is a lot of quantising(?)effect!"

no quantising is not the word for it... (is something completely different in the connection with compression ratio while encoding) anyway i believe what you mean is the effect of "moving walls" (backgrounds) this usually happens when the bitrate is too low...

i think the only way to improve the quality of deinterlaced content encodes is to either choose higher bitrates ( go for more cds) or use filters... (smoothing, or try other deinterlacer settings)

hope this helps

Sorry about the cross post. I realised after I posted that it may have been better in the other forum and tried to delete this one with no success. FWIW this seems to be a problem only with BBC DVD's.

seems to me like a not properly encoded source... as i said before: give the movie more bitrate or just accept the fact that TV shows will always turn our worse than normal film content!
