KVCD: KVCDx3 still not DVD quality?
 

HI,

I just tried a conversion from xvid to kvcdx3 (480x480 skvcd), using the latest script posted on 20/5/03. Conversion came out ok, but very grainy and blurry in parts. I've noticed some people are getting perfect conversions and i'm wondering wot i'm doing wrong? am i using the wrong template?

I checked a friends version of a film and i did exactly same movie, his one is perfect mine is not!

Any ideas plz?

Re: KVCDx3 still not DVD quality..
 

Most of the people that are getting near perfect conversions are using DVD as their source not SVCD's done with XVID.

Someone correct me if I'm wrong, but the more times you encode / convert, the more likely each successive encode will deteriate.

Hi Racer99, thx for reply.

SO ur saying that the Xvids/Divx's were originally svcd's? I can understand that. But if source is perfect quality, wouldnt this make a difference?

No, he's saying that people who are doing near perfect conversions with KVCD are using DVDs as source, not Divx/Xvid ect. Although the Divx you are using may look perfect to you it has already been compressed once from DVD, and compressing it again to KVCD is only going to make things worse. You are making a copy of a copy, not a copy of the original. Some Divxs are better than others, and with the right combination of filters you can get a pretty decent conversion, but it will not look as good as doing the same film directly from the DVD...

Hey TheDJ,

I was going to try to explain, but m0rdant did it for me. So don't give up on KVCDx3, try make one from a DVD, and then base your results. It's hard to get near DVD quality from a VHS tapelike quality based source. Even if it is SuperVHS.

Thanks m0rdant,

That's exactly what I was trying to say. :D

Thanks m0rdant and Racer99, as that's exactly what I was going to say :D

Actually, it's worse than that. You're making a copy of a copy of a copy, since the DVD itself contains whatever defects and compression artifacts the authoring house may have introduced. Of course, as a practical matter DVD source is the best most of us will ever see, but it can be an issue.

I realize some people may consider that splitting hairs, but the number of poor quality DVDs reaching the market now is becoming somewhat alarming. Fully half the DVDs on my shelf are what I would classify as dirty or low quality DVDs, which will make a crappy VCD or DivX. In some cases, I have actually cleaned up the DVD with AVISynth filters and re-encoded to DVD-R for *higher* quality than the DVD. I recently did this with 'Highlander.'
