Turbo Mode for 1st pass with x264

Hi!

I'm still using an old version of MediaCoder, because of its faster 1st pass when I encode with x264. 50% faster than latest versions.

I saw that in my version of MediaCoder, there are 2 options when turbo mode for 1st pass is enabled :
"reduce subq" and reduce "subq and frameref to 1"

Image

this feature has been retired from the latest MediaCoder versions and I missed it because I always used the 2nd option, and now it seems that when turbo mode is enabled, that means with the option "reduce subq" which is also slower.

I wonder if it's possible to get back this feature in next versions that would be great.

Thanks for reading!

This is for more precise bitrate control as quality is always more concerned for 2-pass encoding.
