Bringing sdr footage into my hdr rec 2020 workspace and export

I need help figuring out how to bring some sdr rec 709 footage into my hdr video. I am exporting in rec 2020 hdr, but the sdr portion of the video becomes really dark after export. I need to somehow get the sdr video tonemapped to be viewed in the rec 2020 colorspace. I have tried to just simply increase the exposure of the sdr video, but after exporting in rec 2020 the sdr footage becomes completely washed out and loses information. How can I get my sdr footage to look correct in a rec 2020 hdr render? 

There are many things going on here.  So let me spell out a few key things to understand first.

  1. Premiere requires transmit hardware from AJA or BMD to properly monitor HDR content. PPro cannot drive your HDR desktop monitor yet.  When working in HDR, you cannot trust your program and source monitors - they will look wrong.
  2. Only ProRes MOV and XAVC Intra MXF are fully color-managed at this time. 
  3. Interpret footage is only available for color-managed codecs
  4. Adding color-managed files to a sequence will automatically convert between colorspaces.

 

Unfortuanately, mixing colorspaces like you are with non-color-managed codecs is going to be difficult.  I recomend transcodoing everything to ProRes HQ.  Then use interpret footage to override the colorspace of the HDR clips to the correct HDR color space (probably Rec2100 PQ - is this HDR10 footage?).  Leave the SDR clips alone, Rec709 is correct.  Create a sequence from one of the HDR clips.  This will set up the colorspace of the new sequence correctly.  Then edit everything into your sequence like normal.  The SDR clips will automatically be colormanged to the HDR colorspace of the sequence.  They will never be as bright as the HDR clips, but that is to be expected.  

 

Hope this helps a bit.  HDR is a confusing area and our HDR support is improving with each release.

Did you change the color space of the clips in the project panel ... Modify/Interpret Media, and check the color-space options?

 

What is the timeline color space set to in the Sequence Settings dialog?

Here is a screenshot of the sdr footage under interpret media. Seems as though Color Management is greyed out. Also here is a screenshot of my sequence settings.

So, you're viewing in SDR via Premiere, but exporting to one of the HDR options? That's pretty tough to do and be sure of anything.

 

It isn't easy nor cheap to work HDR. With Premiere, currently, you need the AJA or BlackMagic gear connected between you computer and the monitor to get the monitor to see HDR output from Premiere, as the internal monitors are not yet set to show HDR. The gear is listed in the FAQ on working in HDR.

 

I suppose ... have you read through that FAQ? Well, a couple of them ...

 

FAQ: Setting up for HDR in Premiere Pro Fall 2020

Discuss: Rec.2100 HLG HDR Workflow

 

So currently the general recommendation is to get the AJA or BM kit to connect your computer and HDR monitor, and typically set your sequence color management and Lumetri scopes panels to the same color space. That makes exporting vastly easier.

 

You can try using the Lumetri scopes and sequence both set to Rec2100 in either PQ or HLG ... probably PQ ... as at least, the scopes will show you the tonal range of the image.

Fortunately, I do not need to color grade the hdr footage. Is it possible to get access to color management under interpret footage? I am unsure why it is greyed out. I really just need to tone map the sdr footage so that it does not look so dark after export.

What is that media, btw? What made it, and what is the format/codec?

 

And my comments about color space setup didn't have to do with grading, but simply getting the media on the same "page" for color space.

The video files are .mp4 files. They were captured using Nvidia's screen capture tool. Some were captured in hdr, others in sdr. When I changed the sequence colorspace, the hdr export became overblown and weird, even while using the recommended export settings on the guide you sent. If I export in hdr with my sequence in rec709, the hdr parts of the video look great, but the sdr ones are too dark. If I export in sdr, the sdr parts look great, but the hdr parts look overexposed and terrible.

I can export in sdr and use sdr conform under effects which makes both the sdr and hdr parts look mostly ok, but that defeats the purpose of having hdr footage.

What were you viewing them in? And on what monitor/device?

I am using vlc media player to view the files and my monitor is the Asus PQ27UQ: 4k hdr with peak brightness at 1000nits. Hdr is also on in windows and Nvidia control panel.

It would be very useful if say @Francis-Crossman could pop in here, as this is so flipping new.
