HDR10+ videos are dim on iPhone

Hello dear community,

Unfortunately, HDR videos are dim on iPhone (14 Pro Max & iOS 16.1) when using infuse (7.4.6). Only one tweak help to make it much brighter - switching on screen recording, but it’s not sustainable for the smartphone’s battery. I’ve already tried Shantaram and House of the Dragon in 4K HDR (both in mkv format) and each of them is very dim.

Is there any solution to this?

Thanks

Post media info for your files. I don’t have any issues with HDR or DV content on my phone.

Anybody?)

This appears to be an HDR10+ video. These video may have limited support at this time, but this is something Apple has started adding support for recently.

Would you be able to upload this video so we can review it here?

Only Shantaram appears to be an HDR10+ video, but Barbarian and House of the Dragon are in HDR10.

Do you know any application which can cut MKV video in samples without affecting format and quality? I’m asking, because House of the Dragon and Shantaram are 10GB each. Or I should upload it as it is?

You can upload those sizes. That’s fine. But you can use Mkvtoolnix to trim and split videos.

Thank you. I’ve used Mkvtoolnix to trim the videos. 2 samples were uploaded into Dropbox.

p.s. I just want to highlight again that if you activate screen recording on iPhone while watching the videos through Infuse it somehow makes the videos much more brighter and vivid.

House of the Dragon is notoriously dark and dim throughout. They don’t have a very dynamic HDR. Many people are saying that the SDR versions are brighter and more dynamic than HDR.

Infuse just need to implement gamma adjustment (or luminosity) for hdr and Dolby vision files.

If you try to watch something hdr when not in the absolute dark you’re not going to see anything at all on the screen.

Did you have any chance to test samples?
