Instagram Reels: How to upload HDR?

[patrickvannegri]

What would you recommend for Premiere Pro export settings when editing iPhone ProRes HDR footage for Instagram Reels so it uploads as HDR on Reels?

I edited in Rec. 2100 HLG, exported in the same (codec: Apple ProRes 422 HQ), and tried uploading 4k & 1080p – that looks horrible on Instagram.

Then importing and exporting both existing footage in apps such as Apple Clips, Spark Camera, and other apps supporting HDR export (which were successful uploads), but no matter what I did, and the file size (from 155MB to 8GB), the Reel would be posted dark, pixelated, and nothing near the original...

PLEASE HELP 😞

UPDATE:

Some of my testing posts turn HDR after about 12 hours of being online.
I have checked with many of my friends on my Instagram post on different devices and even on non-HDR screens on Android, and the quality improved, and the image is brighter and sharper than the initial upload. So BANANAS! If I had to guess, Instagram was processing it.

Again, if anyone has a better solution, please let me know!
