Export media way overexposed in H.264

I work with iPhone footage a lot.  My workflow in the past has been converting the variable frame rate footage to a constant frame rate H.264 footage using Handbrake.  Then I would edit that H.264 footage in Premiere CC 2018, export it as a H.264 mp4 file,and everything was fine.

 

This month I upgraded from a 2014 MBP (16GB, OS Mojave) to a 2018 MBP (32 GB, OS Catalina) and from CC 2018 to CC 2020.  Even though I had upgraded to a faster processor with twice the RAM, I quickly discovered that my new system could not deal as well with the H.264 footage as my old system could.  I've still not figured out why that is that case.

 

Since I can no longer work with H.264 footage, I switched from Handbrake to Shutter Encoder to convert my VFR footage to CFR.  While Handbrake forced me to convert to H.264, Shutter Encoder allows me to convert to ProRes 422 LT (as well as tons of other codecs).  So I imported my CFR footage in ProRes, and everything cut together fine.  

 

But then when I went to output the finished product in H.264 (for viewing over YouTube, Insta, etc), I saw in both the Premiere export window and Media Encoder that the footage was WAY overexposed (pic atached).  However, if I clicked the "Match Sequence Settings" box at the top under Export Settings, it would output correctly.  

 

I cannot understand what is going on.  My workaround for now is to export as a Prores Quicktime, and then convert the QT file to H.64 MP4 so the file size is more manageable for internet disribution.  But I cannot understand why this is happening, and it's a pain to have to go throug that extra conversion process.  Anyone have any ideas?  Screenshots attached.

 

System:  

- MBP 2018

- OS Catalina 10.15.7

- 2.2 GHz 6-Core Intel core i7

- 32 GB 2400 MHz DDR4

- Radeon Pro 555X 4 GB, Intel UHD Graphics 630 1536 MB

- Premiere CC 2020 v14.8.0

OBS, Quicktime and YouTube will display things a tad bit different. You can compensate by using a lut at export or by using a adjustment layer. The video below might be helpful.

If you have problems with incorrect color display in clips on the timeline, please pay attention to the new feature - interpretation of the material before editing. It works.

For starters, set the iPhone default so it doesn't shoot HLG for now. There isn't much use of HDR at this time. So leave it at SDR/Rec.709, and life is easier.

 

Next ... for HLG clips, in the bin ... right-click/Modify/Interpret Footage and set the CM section at the bottom to Override to Rec.709. Now click on your timeline panel, go to the Sequence Settings, and make sure the timeline is set to Rec.709.

 

Then you should be able to export with any of the standard presets.

 

Yea, the underlying color system of Premiere 2022 is totally different. Default behaviors have changed. And some things aren't working as the engineers expected, but though they've acknowledged and are working on things, we haven't a clue when the next step of changes will be dropped.

 

I've got a couple FAQs that go into more detail on what's changed, how to work within the new system, and where it's broken at the moment ... including proxies from HLG clips. Plus one on the new monitoring setup for HDR media if you are working an HDR timeline.

The problem is that the iPhone 12 shoots in HDR by default while the H.264 encoder that Premiere Pro uses supports only SDR. And beginning with version 22.0, Adobe changed the way Premiere Pro handles HDR footage by default. Previous versions of Premiere Pro did not support HDR at all, and thus automatically converted all HDR footage to SDR on import/ingest regardless. You will need to conform your H.264 exports from HDR footage manually in the Export settings by checking the box marked "SDR Conform" in the Effects tab within the Export window.

 

The same thing happens when you insert that iPhone HDR footage into an SDR timeline. In this situation, you will need to apply the SDR Conform video effect to any HDR clips in that SDR timeline.

hey, Fly Line Prods

1. if indeed, your footage is HDR, you can tell shutter encoder to process it as SDR rec. 709 16-235 in various dropdowns, then premiere will think its SDR. You can then grade it out like log footage. 

2. shoot SDR

3. sdr conform effect like legend says

4. export HDR compatible codecs in export and upload HDR metadata to youtube for full HDR experience
