Question on XVCD Quality

[Craig Tucker]

Hi
I have a pioneer 636 which will not play SVCD's but according to the compatability list will play XVCD's with a bitrate up to 2500.

At the moment I capture at 704x576 and use TMPGEnc to make standard VCD's I let TMPGEnc do the deinterlace and resize.

I have a couple of questions.

1. Will upping the bitrate noticably improve the quality.

2. Do you have to maintain the VCD standard resolution of 352x288.

Oh yes, increasing bit rate will certainly improve quality and it's very noticeable.
To be even more efficient, use VBR (variable bit rate). This way, low motion scene will get fewer bits and reserving more bits for higher motion scene.
To start with you can try CBR 2400 and see the quality for yourself. Once 700MB CD-R wil hold about 40 mins of video at this constant bit rate.
With VBR (max 2500), you can get even more video time on one CD-R.

First off 352x288 is for pal. 352x240 is ntsc. Don't know which you are going with. They call it xvcd because the bitrate is not standard. So up your bitrate and you will see a great deal of inprovement. around 2100 to 2300 to be safe for your player. However with this much increase in birate you will only get roughly 30-40 minutes on a 700 mb cd-r. But the quality is far greater than the standard bitrate.

Well, according to the compatibility-list at this site, you player does support SVCD! I have a Pioneer 343 and it plays (S)VCD fine (I never tried XVCD, but it should work as well)[/quote]

You have misread the list because it does not support svcd, I know I have tried it. I quoted 352x288 because I live in the uk. What I was wondering was if you could increase the res to SVCD specs but burn as an XVCD, so my player would read it.

Thanks for the replys

Yes, you can, and your player will read it just fine, as long as it has a VCD header and is burned as a VCD.

[Craig Tucker]

So are you saying that you can burn an XVCD with exactly the same specs as a SVCD. Will this acheive SVCD quality. Like I say I would make SVCD but my player wont read them, so this seems a good way to get SVCD quality that will play on my player.

search for "SVCD with VCD header" this will allow you to make an SVCD that your player will be able to play bcz of the VCD header
