Lossless support for other Hardware Encoding

[DDXDB]

I noticed that NVENC H264/HEVC has the Lossless option on OBS, and it seems to be true Lossless. How is this achieved? Is it possible to do this with other Hardware Encoding? In terms of encoders, Intel's Arc GPU also looks like a good choice.

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.
look at

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...

It's just a matter of putting the right settings in. "Lossless" is just a name for a particular set of settings. If you get the settings right, then you don't need the name.

If you're doing this without the name, then you'll probably need to read the documentation for your encoder, to see what actual settings it needs. Do that, and you'll have your result, albeit the long way around.
