render 4k into zoomed 1080p + ignore color managment

hi i just get my new laptop with gtx1660Ti since my 1070 die in september....

so i load all my settings and presets and get problems on new system...

render 4k into in any preset mp4 cuda or prores or any..just take from video i think middle area in 1080p

cut anything else and export in 1080p only this area...

if i put in "filters" tab scale filter and set it in 1080p will video exports full size..but ofc in 1080p...

UPD: if i put 4k prores file or any h264, in encoder with same presets it works good...but any bt2020 become croped

but there is one more problem - it ignore color managment

i work with bt2020 and in premiere i use colormanagment and get normal colors.

but when i render it become like original w/o transforms...

if i try use colorspace filter in filters tab, so any settings i combine, it get me crazy result..i think main reason - thereis no HLG in transfer gamma..

also i just do little google, is it nessesary for voucoder to install 3GB cuda toolkit?

i never install it before an was no problem but now idk..

----------------

driver for studio 460.89, vouk7.1, prem14.7

also i dont know if it possible but can you do something with colors converting ?

i notice that if i convert final proress4444 into 8bit mp4 it do black level more upp, and all blaks becomes gray...but if i out in mp4 10 bits its ok...

i found problem in this video
