I did some experiments checking encoded files compliancy, different settings, authoring, burning to discs.
Decided to use VBV Buffer 25500, Max Bitrate 25500, and using 2-pass encoding at 24000kbps bitrate.
A question to ask:
Using a "Slower" preset and 2-pass encoding makes kind of slow encoding process.
Using a "Fast 1-st pass" option increases encoding speed significantly with small quality loss.
Next step to speedup encoding process and have another step in quality loss is to use "Slow" preset vs. "Slower".
There is a Note at Hybrid:
"Fast 1-st pass - speeds-up the 1st pass of a 2-pass encoding, by lowering some settings. This will result in a small quality loss, which normally is not visible."
Trying to find an optimal quality/encoding speed ratio, curious is this is the right thinking that a slower encoding preset "Slower" and Fast 1-st pass will result in higher quality vs. faster presets such Slow", "Medium" with regular 2-pass encoding?
