Settings for AVCHD 2.0 Progressive compliant file, playback

[Selur]

Should I set Quantization strength to 1 (min allowed) or it does not matter, as far as Lossless is Enabled it is good?

'Quantization strength' is ignored when 'lossless' is enabled.

--nal-hrd vbr

How this can be done?
There is no such setting in Encoding Modes.

Naturally since it's not an encoding mode.
Enable "x264->Base->Restriction Settings->signal hrd" and set it to "vbr" and you get '--nal-hrd vbr' in the command line.
