file size confusion

[fyreboltx2]

i have a dixv4 avi movie thats about 92 mintues long. i converted it to a vcd mpeg (928MB) and realized that itd be a complete waste of a cd for just 12 minutes. so i decided to create a non-standard vcd, i cut out the end credits and was left with about 87 mintues of video. i converted it a non standard vcd (at 937 kbps for video and 96kbps for audio) and it shouldve been around 675MB enough to fit on one cd. but the end file is still 928MB!

i used tmpgenc, i left all the settings alone except the video bitrate and the audio bitrate. can someone tell me what i did wrong?

Was that 937kbps CBR, or 937kbps "average" VBR?

CBR

Why not just.... Split the mpeg into several manageable chunks? i.e. split it onto 2 cds. Quality for VCD is bad enough without lowering the bitrate. Believe me, split the bitch!

well i try to get as much as i can out of a cd. i really dont mind the lower bitrate, as long as its above 800kbps. the video quality is good enough for me and audio doesnt really bother me, i just watch it using the crappy tv speakers.

Heh, I've Seen This Before...

There is a Guide here at VCDHelp that explains how to fit a movie onto one CD-R. One line that is sometimes overlooked involves a particular tab in TMPGEnc - Setting | System | System stream setting. Once there, choose the Stream type | MPEG-1 Video-CD (non-standard) from the drop-down menu. Even if you have unlocked a template, even if you have set a nice low bitrate like 900 kilobits per second, if this is still set to MPEG-1 Video-CD, TMPGEnc will pad the file to fill the 1050 Kilobits per second standard for VCD. That is why your file gets so big, when bitrate calculators say otherwise. I hope this helps!

HUN-YA!

Making it Fit...

fyreboltx2: Hey buddy, I was glad to help! Here, if you really want to thank someone, check out The newbies guide to fitting a movie on one CD using TMPGEnc. Once there you can thank newgen directly for his great work, as I and several others have.

Just so you know, you may find that you can burn as much as 794 MB of MPEG video as a VCD to an 80 min CD-R. The trick is to use VCDEasy and activate its CDRDAO functionality. Though a CD-R may be listed as having 700 MB of storage, that limitation is solely for music. That is because Redbook audio uses larger data blocks with more space reserved for error correction. The actual capacity of such discs when burning data is around 807 MB or so. Some space should be reserved for VCD setup files, which can take up 10-12 MB in VCDEasy. By using the full 794 MB you get more video bandwidth to work with. You can increase that further by reducing audio from 224 Kbps to 112 Kbps instead. Take note that using MPEG stills may decrease the available space for your main feature. I have used this technique to burn your basic 90 minute feature, like Atlantis: The Lost Empire, Cats & Dogs or Shrek to a single disc with very good results, even without cutting out the credits.
