Splitting VBR video across multiple discs.

[ViperXT]

ok guys I have a question for you experts out there.
Take this example: I have a 90 minute movie that I want to spread across 2 discs. I calculate that I can use a bitrate of 2200kb/s for video and 192 kb/s for audio. Now, I enter the following VBR settings into TMPGenc: average: 2200 min: 300 Max: 3500. After encoding I find that the file is 1.6 GB(800mb per disc). Now, because of the nature of VBR, more data is used in certain parts of the movie. So, there may be more data towards the end of the movie. This means if I split the video at 45 minutes the first part may be only 600MB and the second half could be 1000MB. I guess my question is how can I split the file based not on length but file size? I really don't want to reencode.

You have to split it by filesize, the length will probably be the same anyway, it usually is for me, if you want equal length then you need to encode each disc seperately.

used bbMPEG to split the file base on filesize.
