Lossless support for other Hardware Encoding

[DDXDB]

In H264 this is only possible in the HI444PP profile. As far as I understand, HIGH profiles of H264 are not supported in OBS
I did it through H265 but only for old Version OBS
In new versions something was broken, it does 4:2:0 regardless of the settings.

H265 profile1 or "Record at 4:4:4 (RGB)"

I'm trying to record without losing quality (resolution) in different ways. That is, I want to record a file in RGB (or YUV 4:4:4) I set the setting Color Format=BGRA (sRGB in older versions) ColorSpace=sRGB ColorRange=Full MKV recording format (since when recording in mp4 it will also...
