DVD mpegs don't look so good

[zanos]

I just finished creating my first dvd mpeg using svcd2dvdmpg 1.1 and it looks like there are these jagged edges on everything. Is this what I can expect? It seems like a great program except for the fact that the quality of the svcd isn't replicated exactly.

make sure you do a 2 pass encode and do not tick skip resample step.
ive had no probs with svcds.

What are you doing? creating ES or PS? Are you patching /repatching? If so to what value? How are you authoring?

[zanos]

I'm doing MPG -> ES and my horizontal res patch is set to 720. That's pretty much it. Oh my source file is an svcd.

[ChrissyBoy]

well if you patch files to 720 then you will not see the true result until you patch back to 480 after creating your dvd folders via your authoring software.



It might have not been clear on the website but if you patch sequence headers to fool the DVD authoring software then you need to patch the headers back to 480 post authoring. (the intermediate ES or PS files from SVCD2DVDMPG will always be "weird"). So to do this you author the ES files. Produce a VIDEO_TS folder with VOBS etc in there. Now start up SVCD2DVDMPG, browse to the VIDEO_TS folder, choose ES or PS (in order to enable the patching section), click 480. Now click start and the VOBS will be patched back to 480. (choice of first header/entire file is dependant on what you did when you patched to 352 & whether your authoring application produces a VOB per mpg or not)

I repatched it to 480 but it didn't appear to do anything different.

[ChrissyBoy]

what do you authoring with?

[zanos]

I used tmpgenc dvd author.

[yf2001usa]

you don't need to repatch to use the vcds and svcds in tmpgenc author..

[zanos]

I realize that but the quality of the mpegs aren't coming out the way they're supposed to. Edges are jagged looking.

[yf2001usa]

As far as i know svcd2dvd doesn't reencoded the mpegs just demuxes and muxes them so if you got not so good quality then the origionals were not so good quality to.

Bad quality in = bad quality out

[zanos]

It looks fine on my computer but not on my ps2. It's definately not the source.

[ChrissyBoy]

are they vcds or svcds?

[zanos]

svcds

[ChrissyBoy]

Mmm - it is know that VCDs (mpeg 1) are crap on PS2....

I have a similar problem with the jaggies on straight edges in the video.

I used TMPGEnc to encode an MPEG-1 1800Mb/s XVCD. When I burn a CD-R it looks great on my Pioneer DV-343. But when I use SVCD2DVD to author the DVD-R the problem appears.

Could this be an artifact of the player?

[yf2001usa]

I don't know for sure but it might be that your player only supports vcd-dvd which means it will only except exact VCD (not XVCD) on a DVD to play as VCD.
