SVCD maximum bitrate

[fiercekid84]

does all svcd bitrate must be 2600 or 2520 no more but less so that all dvd player can play back smoothly ?????

If you want the SVCD to play in all players then stay within the recommended limits. If you go outside then some players will play it and some won't, depending on how far out you go.

i don't think the bitrate is a big compatibility issue. the resolution how ever is.

Whenevr you go outside the official specs you risk compatibility problems. It wouldn't surprise me if most SVCD compatible DVD players were happy with XSVCD's at a bitrate only a little above the psec but how much higher you can go depends very much on the player. 2700 would probably work in many players but the higher you go the poorer compatibility will be.

Many players that claim SVCD compatibility fail to play SVCDs with bit rates in the higher region - above like 2200 kbps. I'd stay lower than this is widest possible compatibility was my concern...

If you up the data rate on a VideoCD then you have to spin the disc that bit quicker, and that is a problem with CD's - the data isn't as tightly packed as a DVD is, and as such, you may find the player can't read the disc fast enough to maintain a good, stable rate. The disc may not be capable of being spun fast enough, then of course you start getting more tracking errors and the like, and less chance for the error correction mechanism in the player to work.

I never go above the limit on Super-VideoCD but have gone a little over on regular VideoCD's without suffering any problems - TMPGenc has an "illegal" VideoCD template that works very well and gives a little more data rate that sometimes makes a very biig difference, especially considering the limitations of MPEG-1.

Don't mess with the resolutions though, the playing of non-standard discs is very machine dependant - much more so than tweaking the data rate.
