Hdr graphics white, what do I choose?

[Demis98C6]

Hello, I see this when I create a new project. Hdr graphics white, 3 options: 100, 203, 300. Does this affect image quality or color? Which one is the best option for your editing? Thank you

This setting is ONLY of concern if you are working full HDR projects ... HDR media, HDR timeline and monitor setups, HDR outputs. It has no effect whatever on any SDR/Rec.709 timeline/sequence/export.

For any SDR/Rec.709 workflows, ignore it. It doesn't do anything no matter what it's set to.

Basically ... "graphics white" is the brightest tone with any details visible. Think a white paper filmed in sunlight. Bright, the upper edge of any details, but not a specular. Above that value, all image data is assumed to have color and brightness, but not really fine details.

This is a numerical data point needed in HDR video file metadata, to tell the TV/screen what to use for HDR settings internally. So Premiere will put that into the video file metadata on export but again, only for HDR exports.

203 is actually the recommended starting place for HDR whether in HLG or PQ formats. Premiere isn't currently setup to be able to work with DolbyVision.

With the Pr2022 release, they completely changed the underlying color system from what it was when this thread was started. So I'm editing this post to give the best current information.

We can now work fully in HDR in Premiere Pro 2022, using either HLG or PQ, and using only the GPU connection to an HDR capable monitor. In Pr2021, you needed a breakout box from AJA or BlackMagic to get the signal to the monitor, you could not properly work with a GPU/monitor connection.

I'm including the two FAQs below, as to what changed with the Pr2022 release, how to use it, and what's broken as of 20 February 2022. The second is how to monitor for HDR in Pr2022.

How to Set Monitors for HDR work in Premiere Pro 2022?

I'm rather new to the video editing scene. My adobe premier pro automatically auto fills the 203 option, should I just leave it? I filmed all my stuff on the GoPro Hero 8 and it used HEVC.. whatever that means Lol. Does editing in 203 even make that much of a difference?

Again, that setting is only "in play" IF you are working with an HDR sequence settings, full on HDR, and monitoring in HDR also.

Otherwise, ignore it.

It has no effect whatever with Rec.709/SDR timelines.

What that setting does is tell Premiere where to set the "graphics white" HDR data point in the file metadata, again, if you are working in HDR. "Graphics white" ... it's the lightest point with details still possible, think a white piece of paper in sunlight. It's a necessary data point for including in HDR video files for screens to use to set the proper image settings for the screen.

Yes, just literally ignore it. It won't make any difference to your GoPro footage.
HEVC is just a newish way of compressing your files so they are smaller without losing too much quality.
