Question / Help I444 color format, encoding 420 444 both, yuv color range

[RaceDriverMIKU]

Hello.
I want to record video 4:4:4 chroma subsampling, so I set color format as I444, and high444p.
But at the same time, I want to stream as 4:2:0, but If I set color range full, the color become inaccurate. and I found that at 4:2:0, partial is the right color.
I did very short test before, which is just recording and looking, it was just same, but is there any actual different between color range partial and full, when I record video as 4:4:4, high444p?
or the only way is I need to open 2 obs at the same time?
Thank you.
Screenshots are taken via Galaxy S7, display color format is Adobe RGB

I don't have an answer for you ("should I do this or should I do that?"), but to get a deeper understanding of color format and color space and how to deal with them within OBS, consult this guide: https://obsproject.com/forum/resour...t-color-range-settings-guide-test-charts.442/

koala// Thanks for the answer, but, hmm... I guess there is no way that use color range partial(stream) and full(recording) at the same time but opening 2 obs.

If the output supports Full Range, OBS Studio will output in Full Range.

Suslik V// Thanks, but I should mention this first, I use QuickSync for streaming, NVENC for recording. I like Lookahead VBR.
If YUV color range is set as full, image gets too dark, also I test it with NVENC, high profile(4:2:0?), it also gets too dark.
4:2:0 chroma subsampling isn't designed for full YUV color range? or... it is about how video players are processing 4:2:0, BT.709, full range videos?

I don't have HW to check this encoders.

YouTube for example, supports Full Range input, and video will be converted (without any clipping) to Partial Range by YouTube itself. Also, you may try to stream to any local PC, and see how all works, but, please, take into account: https://obsproject.com/forum/threads/settings-advices-red-color-problem.84499/#post-351536
