Anyone can help me cook up the right command for this?</p>

Can you share the sample file, say via dropbox? I can assist

I'm currently investigating a solution based on `libplacebo` for this, will report back with findings.

Still investigating, looking into the ffmpeg build for Jellyfin. `libplacebo` seems like a dead end on this one.

# How to convert Dolby Vision HDR to HDR10+?

(Asked by: username_0 on 2021-05-25)

I'd like to convert a file recorded from an iPhone 12 to a royalty-free version (for upload to Wikimedia, Flickr, etc). So the transfer involves:

| Source (iPhone proprietary-encumbered) | Destination (royalty-free) |
| --- | --- |
| 4k 60fps (UHD, not DCI) | 4k 60fps |
| BT.2020 in HLG (WCG) | BT.2020 in HLG (WCG) |
| Frame-level dynamic HDR metadata in Dolby Vision profile 8.4 | Frame-level dynamic HDR metadata in HDR10+ |
| HEVC | VP9 (open to AV1 as well but that's likely more nascent) |
| Bitrate is 31 Mb/s | Fine with higher bitrate to maintain same SSIM/PSNR |
| Audio is in AAC | Audio to Vorbis/OGG |

According to <https://codecalamity.com/encoding-uhd-4k-hdr10-videos-with-ffmpeg/> it should be possible to do most of this.
Anyone can help me cook up the right command for this?

[Sadly no](https://www.reddit.com/r/hometheater/comments/eholm5/dolby_vision_to_hdr10_conversion/), not without expensive specialist broadcast processing hardware.
