CBR o VBR in SVCD to play in DVD standalone player ?

[2573]

Well, i have made a SVCD, in the Pc goes ok, but when i play in the DVD, sometimes, in the same moment, the image stop one frame, and after that one or two frames goes ok till the next pause. I have read in somewhere it can be caused by a high peak in the bitrate the dvd can-t play, so i have thought if i do my svcd in CBR ( around 1800) the problem will disapear, is that ok ?

Thanks.

VBR will always give better quality than CBR unless the CBR is almost as high as the maximum bitrate in VBR.

If you used VBR before just do not set the maximum bitrate too high and you should be ok. If you used CBR then 2520 is standard and should not be a problem if your player supports SVCD.

sorry, i dont understand well, you want to say i put a very high bitrate...

[Bondiablo]

2520 is the standard bitrate for SVCD, lowering it will actually make your disc less likely to play on your DVD player because you'd be making a non-standard xSVCD. If you originally used 2520 CBR then bitrate isn't the problem.

That's actually incorrect Bondiablo.

2520 kbit/s for video is the commonly quoted reasonable maximum bitrate for SVCD.

Anything less than that is perfectly within specification.

ok my mistake 2520 is the maximum standard and lower would only be non-standard if used in combination with VBR but if his DVD player supports SVCD it should play one at 2520.

Um, SVCD can use VBR encoding. So as long as your maximum bitrate is less than about 2520 kbit/s it is perfect within spec (whether you use VBR encoding or not).

ok i give up, what the hell makes for an xSVCD then? just going over 2520?

[vitualis]

Read the SVCD specs: http://www.vcdhelp.com/svcd

Going beyond one of them makes an XSVCD. For example, max. combined bitrate over 2x CD, or a non-standard framesize (e.g., 704x480/576), etc.

yes, i read the specs after your first post but i took variable in that instance to mean the bitrate could be anything up 2.6mbps not that it could also be VBR.

[vitualis]

It is both. That is, the max. bitrate can be up to 2520 kbit/s AND it can use VBR encoding.
