Bitrate Calculator and TMPGEnc 3.x XPress

[Tolwyn]

First of all, I'm assuming the "XPress" doesn't mean I bough a higher version number with less features, does it?

Ok.

1:27:00 DV 720x468 Video
224 kbps MP2 Audio

Putting on a standard DVD yields a bitrate estimate of:

6781kbps

So...
I launch the encoder, choose VBR and when I input that number per the instructions on the Calc page... it says it's going to be 105% or something.

Will the estimate be wrong? Is the calculator wrong?
Does the calculator account for a modest menu?

I put in 6700 to be safe. 20 hours remaining.

According to vcdhelp bitrate calculator your bitrate should be 6058,looks like you will go over,make sure tmpg says its 100% and double check your calculation.

You're spot on, Tolwyn

What you'll find is that TMPGEnc classes a DVD's capacity as 4200MB, even though you can go pretty close to 4482MB in reality. 6700kbps video and 224kbps audio (in theory) will give you a 4412MB output, which will be fine.

My mistake,maybe i need glasses ,one thing is you have to account for is some overhead which is usually 100-200 mb depending on how many tracks you are using.

Nah, shit happens mate. We can't be right ALL of the time

@Tolwyn:
The calculator does not account for menus. It literally works out the bitrate to absorb right down the the last MB of disc space, so generally I'd subtract 50-100 from the bitrate the calculator like you have. This should give you plenty of space for a modest menu and will keep you off the very outer edges of the disc also. You could always enter a custom output size in the bitrate calculator too - such as 4300MB or whatever.

Cool. Thank you very much. Looks like it's going to be close. I'm still encoding, believe it or not... 18 hours total. Good grief!

I can always do some minute cut editing if I have to to get it to fit.
