i need help WITH SVCD

[perginewbie]

does it matter how big the file is because i heard size dosent matter only time 40 to 30 mins so lets say the file is a gig

[poopyhead]

?? i'm very confused...what do you mean "matter"???

if you're referring to fitting SVCD on a CD-R, filesize does MATTER. a 80 min CD-R will hold a max of 800 MB on mode 2 (S)VCD burning.

you might be able to overburn..but that might add only an extra 50 MB...but overburning may damage your burner and make the CD-R not readable. it's a risk.

if you have a gig file, you will need to split that between 2 CD-Rs.

thanks im still not sure what to do i have a 1.3gig avi file and i want to convert it to svcd but the problem is due i spilt the video every 40mins or just at 700mb

[fmctm1sw]

every 40mins or just at 700mb

There is a constant bitrate for a standard SVCD. You will not be able to differentiate between minutes or megabytes. One increases constantly with the other. How long is you original AVI file?

[perginewbie]

the avi file is about 2 hours

[fmctm1sw]

the avi file is about 2 hours

I guess you'd need about 3 cd's then (120 minutes). 40 minutes will be roughly 700MB. What conversion program are you using?

[perginewbie]

i was using some avi to svcd program by Aare and it said it would take 3 days to convert so im just using TMPGenc now because it said it would take less than a day roughly under 15 hours to be exact

First things first... due to the nature of (s)vcd recording you can actually put 800mb of mpeg on a disc and not 700 ( assuming 80 minute disc ).

Unless the movie is a wide-wide screen film splitting to 3 discs is the best best. If it's really widescreen you can probably get away with 2 discs. Once you decide on how many discs, then you know your bitrate and can go from there. With 3 disks ( 40 minutes each ) you can just use CBR 2500/192 and get excellent results. VBR would be waisted because you can't peak higher than the average ( due to limits in SVCD ).

If you go to 2 disks you will have to use VBR and figure out your average bitrate as appropriate.

True, and sound advice for you pergie, but now you're making an XSVCD. Make sure you DVD player can play it if you plan on watching it on your TV. Or check out CVD, which people have had nice results with...

thanx for all ure help

[perginewbie]

im making a svcd im using tmpgenc at 2500 CBR the orginal file is 1.3gig and 2 hours

I thought a (standard) SVCD was 2520 CBR. Maybe I assumed that since that what my TMPG template says?

[snowmoon]

Read the SVCD specs. It's UP TO 2700 ( give or take depending on who you talk to ) video + audio and it can be VBR.

Yeah, I was temporarily an idiot..... Got so used to seeing 2520 all the time...

VBR is a must, especially if you want to fit a movie on less CDs.

i know i'm beginning to sound like a used record, but giving the same bitrate to the end credits as a fast action scene doesn't make sense.

VBR allows you to shift some of the unnessary bitrate from low action scenes (i.e. end credits...scrolling text doesn't need much bitrate) and give them to high action scenes, which generally do require more bitrate.

CQ VBR's filesize isn't very predicatable. however, its encoding time is quite fast.

multi-pass VBR, using an avg. bitrate can be just as predictable in filesize as CBR. however, it does increase the encoding time considerably...depending on the CPU.

Maybe to some of us but I'm sure that perginewbie hasn't heard it before and this is the newbie section. 8)
