A question regarding b-bias

[Terranigma]

Can blocking occur if this setting's altered, specifically in scenes where there may be fire or in dark areas in general?

[TheRyuu]

My guess would be that it would depend whether or not the b-frame would have a higher quant value then the other frame that would normally be there (or even if it had the same quant value, wouldn't the compressibility of b-frames cause it to block more? which is kinda just asking the question you asked again... :p)

I could be wrong though so please don't take my word on that :)

You have some weird idea of "compressability". If something is very compressible, that means you can encode it without many artifacts.

And B-frames always have higher quant than the nearby P-frames. --pbratio makes sure of that.
