Originally MPEG1 VCD aren't supposed to be above 1800 Kbps. I guess that even muxed in SVCD, that is the same. MPEG2 SVCD can go up to 2800 (3200 may be ? not important...).

So MPEG2 SVCD should be your solution.

I've never heard this about the bitrate maximums before.

MPEG-1 shouldn't get higher than 1800,
MPEG-2 shouldn't get higher than 2500 (or so) with SKVCD?

Why isn't this posted on the main site, or is this just personal preference?

These are the maximum bitrates supported by most standalone DVD players.

Hi everyone,

I already asked if I had to post elsewhere...

Anyway, Phil, second test is successful (MPEG2 SVCD).
At first sight, it isn't quite bad.
You always say MPEG2 is visually poorer than MPEG1: what precisely should I look at?

I only regret MPEG2 algorythm isn't free...

So I guess I have one last chance: MPEG1 muxed as VCD and burned as SVCD. Would you bet on it?

He was tlking about the bitrate limits I gave, not about your question :-)

Dancing blocks in dark scenes, mosquitoes around edges in static scenes.

I'm not sure it can be done. You will miss the SVCD scan offset that will be added on the fly and your video size will increase a lot over 800 MB.
But it's just guess, I never tried.

Hi Phil, as always, you were absolutely right. I guess Nero added something on the fly and the result was a file impossible to fit in 1 CD.

I will keep on making tests because I don't give up making KVCD with MPEG1 encoding.
