Max Bitrate Video Bitrate SVCD,.. 2600 or 2472 ?

[AE-35]

Like the topic states,... is it 2600 for only the video or 2472 for the video plus 128 for the audio making the total 2600.

As per enclosed link (all about SVCD and where it originated from etc.) it clearly states "Video : MPEG2 VBR, average bitrate up to 2.6 mbps"

I think Vitualis said it best, something like...

no matter what you do, you only reach other levels of noncompliant. Or close, to that.

It depends on what software you're using.
I-author=2600 total max mux rate.
BBmpeg 2376+224=2600.
LSX 2414+128=2542, but when checked for bitrate, it's 2472 like their 1123=1150 so 2472+128=2600.
TMPG 2520+224=2764.

Philips has 2.66mbits listed as max muxrate in their toolset for tracks, and 2.33mbits/s for sequences. The verifier says something like 2,788,800 bits. Which happens to be the speed of a 2x CD. Of course that spec could be for the total program stream including flags, time stamps, and other things that take 4 bytes here, 1 byte there.

So who really knows?
Vitualis?
HVR?

@disturbed1

to add to your list. If you take the standard SVCD template from the dazzle capture card (DVC II) it's
2400+224=2624

And another at 2600, well close enough.

I guess to be on the safe side, one should stick at 2600.

I haven't experienced any problems with LSX, or BBmpeg.

I've heard the DVC's SVCD's are compliant in stand alones as well.

aldus4, do have, know of any other products SVCD's specs? It would nice to see a few more posted.

Ok, to be on the safe side I'll just have to keep a max muxed bitrate of 2600, right.
I started this topic because I found that when the bitrate goes above the standard SVCD bitrate, my pioneer 535 begins losing sync after 10 minutes ( it goes gradualy out of sync ).
The only problem is that there are no mpeg encoders that I know of that respect the max bitrate setting I give them, so I have to encode the movie and after that check it in bitrateviewer and when the bitrate goes over the max bitrate I have to encode it again at a lower bitrate, so that's why I wanted to know the total max bitrate for a standard SVCD.

@disturbed1

Yes, the SVCD made from DVC II are fully compliant. But it is interesting that someone once made a norm that really no one obeys <grin>. But as the norm is defined as anything up to 2600kb/s (pure video) I suppose anything goes.

As for other product specs...can't think of any other at the moment.

@AE-35

Yes, you will find that every standalone DVD Players allows different max. bitrates for SVCD. Mine goes up to about 4000Kb/s, others can do around 3500kb/s. What I still can't figure out however is if they can play a DVD @ 9800kb/s on mpeg2, why not a SVCD at a lower bitrate on mpeg2?
