How To Convert HEVC HDR Video for Premiere?

[danield25437812]

I'm capturing game footage using NVIDIA GeForce Experience and the files come out as HEVC 10 bit 4:2:0. My project is fully set up for HDR (Color Space 2100 HLG, Maximum Bit Depth in sequence settings, HDR Graphics White at 300 in Project settings, extended dynamic range monitoring in Preferences) and my monitor is HDR, but I'm reading that Premiere doesn't support HEVC video. When I watch in Windows Movies and TV player or VLC, the color is all correct, but when I import it into Premiere its washed out and I have to heavily color correct. I also couldn't find any programs that convert HEVC into an HDR format that Premiere understands. (I can playback HDR video in Premiere if it's not HEVC).

Does anyone know of any programs (paid is okay) that can convert this to an HDR format Premiere likes?

Are you using Shadowplay? I use Shadowplay all the time without any issues but I don't have your editing system. I would try to double check all the settings in Shadowplay, Premiere Pro and your Nvidia control panel. If worst comes to worst you can use an adjustment layer. The video below might be helpful.

Yes! I'm using shadowplay. That's awesome that its working for you, what Premiere Pro settings are you using?

[Andy 1968]

I use default settings. Keep in mind I don't have the same computer system as you. Instead of capturing a game try capturing the Windows desktop and see if that works. If it does then there might be a few settings in the game that need to be tweaked to work correct with Shadowplay and Premiere Pro.

Have you tried setting your Project and sequence to 203 on the diffuse white? That's not the white point, but the diffuse white point, a very different thing. Typically the 203 figure is more common. Above that figure it's mostly speculars on most programming.

Past that, are you using a transmit out monitor, as for many the Program monitor doesn't work in HDR yet. And ... I'm assuming you have your computer set for HDR monitor?

Hi! Thank you for your help here. I'm not sure where I'm able to change the diffuse white point, I just see the one option to use 100, 203 or 300 on HDR graphics white in the Project settings. Here are some photos (taken from my iphone cause screen capture might not accurately represent) of my settings, and the difference between the video in Premiere and using VLC.

I'm using an HDR monitor with HDR on, and I have definitely switched HDR on in Premiere before and have been able to get HDR level white points. I tried using my HDR monitor with Mercury transmit, but it gives me the same video output as the program monitor. It seems its only when importing HEVC video it gives me this issue? Maybe I just have to color correct it? But I would rather it just be natively what comes out of the program and not my closest approximation.

Thank you!!

They've just released a public beta with HEVC HDR support, I think that might be the issue. Here's the thread from the public beta forum announcing it.

Thanks so much! I downloaded the beta, and now my videos are displaying properly! Now I can see their color space in properties and I saw that the video files I was inputting were Rec. 2100 PQ, but when sequence settings are 2100 PQ, they still look bad, but then I switched the sequence to Rec. 2100 HLG and now it looks just like it should. Thanks again!

The whole color management thing in PrPro is currently a work in process. So many changes, most of which come in one part at a time I think so they can test out how one bit works by itself.

Does make working with the app a bit more challenging as it's a moving thing at the moment.

There is additionally another Project setting accessible, permitting you to choose the HDR Graphics White point with 100 (old SDR), 203 (new accepted norm) and 300 (extremely splendid) being the three choices. Setting to 203 will permit your SDR content to be supported a bit to all the more likely match your HDR content. Altering is fundamentally something similar until you begin playing with shading amendment. The Lumetri Scopes board should default to Rec.2100 consequently, yet you might have to change the scale to HDR in the lower right corner www.lezaalava.com/portal-seiem/
