Handle HDR10 footage in Premiere Pro

[jriker1]

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.

Maybe @R Neil Haugen has some ideas.

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.

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.

[R Neil Haugen]

If PQ, use PQ settings instead of HLG.

[jriker1]

That's the problem. I open the footage and look at thte sequence settings.  Seem right

So I look at the interpret footage.  Looks right.

This is my settings when exporting

Problem then I'm left with the variance in color as originally noted.

Please share the details on PremierePro version you are using.

please try what is suggested by @R Neil Haugen I.e. select a PQ export preset.

or you may share a sample footage to help you.

Thanks,

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.

[jriker1]

Sorry can't edit.  Not sure about my two questions but looks like using that preset may have helped.  Looks like the original, MOV and ffmpeg encoded HEVC look the same. 

[R Neil Haugen]

There are picky little details it is so easy to miss, and if any one them them isn't set correctly the HDR will not either export or be seen properly if it does.

Hence my recommendation to always start with the correct type of HDR export preset.

As to the questions, well, it depends.

For typical Web YouTube use, leaving the 8bpc set as such will work.

If you need a higher quality to potentially re-edit, then you want the MAX Render Q and 16bpc settings.

[jriker1]

Ugh.  Guess I was premature.  I just tried the same process with another video and the final output is darker and more reds in the face and such.

[R Neil Haugen]

Is that how it looks when that clip is reimported into Premiere?

[jriker1]

I load the exported MOV into premiere on another track and when turning them on and off do not see any variance.

Side quesiton sa I tried encoding thru Media Encoder and Premiere Pro directly. In Premiere Pro there is an option to "turn off" Effects.  When I do this is it turning off any effects I have added to the timeline like Neat Video or is it just turning in the built in Effects listed in that area?  I notice at least in Media Info something that takes 25 minutes to encode could take 5 minutes when encoding in Premiere but I also disable Effects as part of it so wasn't sure.

Edit: As to the comment from your last post, then I'm wondering if there's an issue in your monitor setup.

So ... is your monitor actually capable, and properly setup, for PQ forms of HDR?

And what is your OS?

As to the last post questions on the Effects at export ... sometimes, a little poke of the box is a useful thing, even if scary for those starting out at times. But happy to help here! And keep asking questions ... ain't none of us knows the whole flipping app's bazillion options!

Notice the arrow to the left? That, in The Adobesphere, is a twirly thingy. A twirl-down arrow to get more stuff showing ...

And I think is mostly intuitive. Anything selected here, you have the blue butto to the right blue at the top of this section, gets turned off.

Anything not selected, isn't turned off.
