Capturing with GFE, color space

[Amaze]

I just noticed that the video files produced by GFE are in limited range, is it possible to make capture full?

[Sharc]

Use QPH

[Amaze]

What?

[Eric-jan]

You know for sure your hardware is using full or limited ?

That's what mediainfo says. I should clarify, gfe is geforce experience.

Ahhh.

- Run the NVIDIA Control panel
- Video -> Video Color Adjusments (or similar text)
- Enable 'with NVIDIA settings"
- Tab Advanced (or similar)
- Dropdownlist Dynamic Range; select Full (0....255)

Yeah, correct Sharc, Mediainfo tells only "after the event" the specs from the "result" … the file.
what i under stand of it, is that as soon if HDMI in consumer products is in the chain, it's the limited range 16-235/255
working only with computer/pro video hardware it's full range 0-255, i'm still learning in this area, it's an important thing when making a setup, and doing post work.
Even the semi pro people have to be very alert with this.

That didn't change anything. It looks like those settings are for overriding video playback, not recording.

Could be, but that's also important, most of the time the "limited" setting is the correct one, unless you notice "banding"

Unless you really know what you're doing I recommend sticking with limited range YUV. All commercial and streaming video uses limited range. Your computer and software should be set up to convert limited range YUV to full range RGB for display or filtering.

Good subject here ! But by "commercial" you mean consumer ? when you say the conputer should be set to convert limited to full range, this is "only" for playback, i guess.
Talking about a computer with a computer monitor with HDMI,DVI or DisplayPort, would mean it's a full range color setup for playback. (not a NUC (miniPC) connected to a flatscreen TV, which is a different story… i guess)
The devil is in the details…..
I guess there are only few capture cards or expensive ones that capture in full range color, it's the hardware that dictates the setting for full or limited range color..
correct me if i'm wrong.

You're eyes can't see YUV video. It has to be converted to RGB for you to see it. That is where the conversion from limited range to full range takes place. Limited range YUV is converted to full range RGB. By commercial video I mean Blu-ray disc, DVD disc, broadcast TV, broadcast satellite, Netflix and all the other streaming services, youtube, vimeo, etc.

I see. I assumed because I play in full range I should record that way too.

But if the final destination ie. Youtube, is limited range than I should do the initial recording in limited too?

I still don't know why GFE records in bt.601 though when from my searches hd content should use bt.709.
So I think I will stick to OBS where I can set bt.709.
