Question

Handle HDR10 footage in Premiere Pro

Latest version of Premiere Pro.

Running on an SDR monitor

Have 4k HDR10 footage

Want to use Neat Video to reduce grain on some older 4k footage.  

Export losslessish (like ProRes)

Want to then run thru ffmpeg with x265 and reduce the final output.

 

Problem I'm having is when I open the source in Premiere or play it in my system it has what you'd expect I guess for a washed out look considering SDR monitor with HDR10 footage.

I open the source in Premiere Pro and it comes up as I would expect as Rec 2100 PQ in the sequence.  No matter what format I export in the footage comes out looking like it was converted to SDR

Only way I can get the final output to look at all like the source is to interpret footage on the original import and change the color space to Rec 709 but then the final output is Rec 709.  When I then export the above MXF footage, injecting the HDR10 metadata with ffmpeg it's weird.  Looks the same in VLC in a snapshot.

But it's super red on my non HDR screen.  I'm hoping I don't need an HDR screen for Premiere to work to complete this workflow.

For this workflow only wanted to use Premiere Pro to use Neat Video as own it and proving to be a challenge.

Several things must match for HDR work:

  • Clip color space be Rec.2100/HLG
  • Sequence color space be Rec.2100/HLG
  • Export preset MUST be one of the included presets, and has HLG in the preset name.

 

IF those all match, you should get an HLG file out of Premiere.

 

Modding a preset to HLG, theoretically could work. But has a ton of details that must all be exactly set. Use theirs to start.

Everyone's mileage always varies ...

    Thanks for the reply.  Let's start with your first item.  I believe its Rec.2100/PQ but Color Space says YUV in MediaInfo.  Can also share ffprobe info if needed.  So it's HDR10 I know and thought it was Rec.2100/PQ.  Is this accurate?  I attached a MediaInfo dump of the video file info.

    23.5.0 (Build 56)

    None of my presets have PQ in it so had to click More Presets and found a few.  Selected Apple ProRes 422 HQ PQ.  Looks the same as what I sete manually but what should I set for:

     

    Depth: 8-bpc or 16?

    Check box Use Maximum Render Quality?

     

    Was thinking leave at 8 and unchecked if I'm using a preset assume the thought it to use what it sets?


    Interested in the answer to the two items I mentioned however is it possible that different codec and containers can cause the display to be different?  So for example the source I put into an MP4 container and is HEVC.  The interum output is MOV and ProRes.  Oddly the final output looks the same as the interum however if I open the interum in Premiere Pro and put it on a second layer, turning on and off the layers seems to match.  Playing them in VLC seems to show the variance.

     

    Not sure if how Premiere displays things matters though if the final output looks different.

    Maybe @R Neil Haugen has some ideas.
