  VBR settings not taking…

  Posted by Randal Petryshyn on February 5, 2011 at 5:31 am

  Hi
  I recently upgraded from 8pro to 10pro. When I have a larger file to render for DVD, I rely on setting the mpg VBR. In version 10 my file size is always too large. In checking the resulting bitrate, I find its not what has been set at. This always worked perfectly in my past versions….

  What could be wrong?

  Thanks in advance

  How do you go about checking the VBR in the finished, rendered file?

  Hi
  I check the VBR “max and avr” bitrate in TMPgenc. It has always been spot on with the other versions. Now when I render a file with calculated bitrates, the files are always too large. When I set the average bitrate to 4500, it comes out as 4770.

  I don’t understand it!

  Thanks

  I have rendered the same project in Vegas 8 and Vegas 10 using the same VBR mpg encoder settings. The Vegas 10c files comes up approx. 10% larger in file size!?

  Any ideas?

  Thanks

  Wow! That’s like an extra 1mb in 10mb, 100mb in a 1,000mb and so on……

  What’s all that about?

  Yes, its a pain. When you render a project over 90 minutes to fit a DVD it becomes a pain. It would be nice to have the “fit to disk” option. It would settle for just a accurate VBR average…

  Well, yes it is a pain, but I don’t think that that’s the end of it. Somebody needs to rigorously test this because having “identical” render templates achieve such, OR ANY, variation from VP8 to VP10 should be a concern.

  Grazie
