Rick, what I neglected to mention is that if the program is 70 min. or less, I use a custom CBR of 8,000,000. Some folks have gone as high as 8,500,00 but I prefer to stay on the conservative side hence the lower number. Anything longer and it’s a 2-pass VBR using the numbers from the calculator.
This assumes the AC-3 default setting of 192 Kb/s.
Use good name brand media and you’ll never have a problem.
My preferred media is Taiyo-Yuden Watershield (great if you want to print on it!!). If I can’t get that brand, then I will use Verbatim. These are the only two brands that I trust.
I should mention that DVDA sometimes get confused and says that the file is too big and needs to be recompressed. If you’ve checked your files and you know that you’re under the 4.3 GB. limit (as you will be), ignore the warning and everything will proceed as normal.
Lastly, you may want to make and always use the following custom AC-3 preset to ensure that your program is as loud as you expected it to be.
Encode set to AC3;
Click on Custom tab;
On the first tab, set Dialog Norm at -31 (this sets it at unity gain);
On the last tab marked Preprocessing, set the Line Mode Profile and RF Mode Profile mode to “none”;
DC High Pass Filter On (this operates at <=3Hz and takes DC bias out of the mix);
Bandwidth Low Pass Filter On (this takes aliasing noise at >20kHz out of the encode).
Save this as a preset.
