TMPGEnc output MPEGs files too big!

[spadgham]

I am trying to create a MPEG file for VCD authoring in TMPGEnc. I want to get an avi file onto one 80min CD. I've followed the one disc VCD tutorial on these pages to the letter, but despite creating my own "One disc VCD" template in TMPGEnc and being able to alter the bitrate on Bitrate Setting screen (4/5 of the Project Wizard) to ensure the output file fits on an 80 min disc I always end up with a massive 900mb file which is too large to burn. I have tried authoring in both VCDEasy and Nero but still no luck. Can anyone help please? This just doesn't make sense!

Try http://www.kvcd.net/dvd-models and download one of their templates to use in TMPGEnc. Also check the chart on this page to see if your standalone player will play KVCD's.

You may want to try another version of TMPGEnc, I recall that one version had a bug that resulted getting large files, don't remember which one but I think it was 2.59. So maybe try another version.

get the newest version and use a bitrate calculator. if its more than 803 mb reduce the bitrate more.

Keep in mind that changing the bitrate of a VCD means that it is no longer a VCD, but rather an XVCD, which has considerably less support in terms of DVD players that will handle it, etc.

With VCD, you have a fixed bitrate (it's actually called CBR, or Constant Bit Rate) of 1150 kbps, and this cannot be changed. Well, obviously it CAN be changed, but the resulting file will no longer be within the VCD specifications.

That said, if you really want to reduce the file size of an MPEG, you're going to have to sacrifice quality. That's just the way the math works out, and there's simply no way around it.

You can do so by lowering the CBR value to something less than 1150, though I highly recommend against this, as the quality will begin to deteriorate rapidly the further you go.

You can also try a VBR (Variable Bit Rate) setting, similar to SVCD, and just drop the numbers as needed. That way you can get away with a black screen using next to no bits, while a high action scene uses more bits. It is a bit more efficient, and you'll probably have better luck with this method, but it will still not be "to specs".
