How to Burn SVCD with Nero (Settings)

[hiflyact]

Hello,

I have a SVCD format video, 480x480, bitrate was encoded with 2 pass VBR in TMPGEnc, so it's not the standard 2520 bitrate. What settings do I need to check on the 1st screen so Nero does not re-encode or try to stretch the bitrate to fill the disc up with? Is it as simple as unchecking the "Create Compliant SVCD" box? I guess I need to change the CD minute amount to 80 too? I don't want Nero to do anything but burn it as is, no changing it in any way.

Thanks for any help

yes

so it's not the standard 2520 bitrate.

there is no SVCD standard bitrate per se like VCD. standard VCD is 1150 kbit/s CBR. for SVCD, standard is as long as you keep total bitrate (video + audio) to under 2778 kbit/s. even for audio, SVCD has a range of bitrate to choose from and still be standard, unlike VCD...which is fixed at 224 kbit/s. in SVCD, your audio bitrate can go between 32 - 384 kbit/s.

so both SVCD video and audio have a wide range to choose from, so as long as both audio + video bitrate doesn't exceed 2778 kbit/s, you're still within standard.

it seems your .mpg is standard SVCD, so try and burn it as standard, if you can.

Well, I don't think it worked out the way it should. I used AVICodec software to see the bitrate on the video I am burning, 2496 and is 795MB in size. When I burn with Nero, either checking the "standard compliant SVCD" or not checking it, I get the same results which are these: the bit rate of the burned video is now 2266 and the file size shrank to 792MB. Is this what is supposed to happen? Where did the 2266 come from, could that be the avg bitrate? I'm confused, because I think Nero is messing with it to try to get it to fit.

after you load the .mpg file into nero's SVCD template (assuming you still leaved "make standard, compliant disc" checked), does nero pop up a dialogue box??

i.e. does it tell you the .mpg isn't standard?? does it ask you to re-encode?? does it tell you that the file is too big??

i highly doubt the last one because i've fit about 795.61 MB on a 80 min CD-R.

No, no dialog boxes come up stating it's not in the right format, nothing about re-encoding either, or saying it's too big. I just wonder what's up with it? It doesn't even ask me if I want to overburn the CD.

then, i don't think anything was really changed....

so long as the SVCD works..

Yeah, I just wanted to know why AVICodec reports the file size being smaller and reporting a lower bitrate then the original non-burned copy. It's just a weird thing I guess. Thanks for your help.

However when I used IsoBuster to extract the video form the svcd and ran the AviCodec program on that file compared to the original, they matched perfectly. Must be something with Nero, but the files were the same.
