A shortcut to see HDR content via Apple’s EDR technology on some Apple devices with the latest iOS/MacOS versions.

Update fall 2021: This page works as intended when it is viewed in Safari on an iPadProXDR. But only with the YouTube links, not the Vimeo links anymore.
The page worked also on my previous iPhone 11 Pro, but it does not on the newer iPhone 13 Pro anymore. I have not a clue why this happens.

On iOS (15.1) I can see the intended image when entering the iOS YouTube or Vimeo Apps (Vimeo shows some glitches)

A iMac 27″ from 2020 or a MBP from 2018 does not show embedded YouTube links in HDR with Safari, but with Google Chrome it works just fine.

I found a thread on MacRumors about this issue.

On MacOS (12.0.1) I can see a bright HDR image in the Vimeo desktop application, which plays back videos in a small window next to the menu bar only.

I could check this page on the new M1Max MBP in Safari. Safari does not show HDR content at the moment. I am not sure why this is disabled.

All the pages related to HDR content need to be viewed directly in Chrome or Safari (it is not working in a browser within the Facebook or LinkedIn Apps as of October 2021) in order to watch the embedded Vimeo clips in HDR/EDR.

Watching HDR content seems always possible via the native Vimeo or YouTube Apps, also on Android devices.

I am also slowly digging into the technology that Apples uses to make HDR possible on their devices. Here is a link from Apple that is worth studying: Displaying HDR Content in a Metal Layer

Test, Test, Test, …

This is a standard dynamic rage or SDR image.
This is the same clip as above, but uploaded to YouTube. Some Macs can also display HDR content directly in Safari.
This is a high dynamic range HDR clip (if it is presented visibly a lot brighter by your smartphone)
On iOS devices it works for sure when watching the clip in the YouTube app.
Why not keyframe the three light situations and create a light animation. Rendered with the AMD ProRender engine.
The same light animation, different shaders and rendered with Cycles in ACEScg.

My test results so far, what works and what does not:

  • viewing HDR in Safari with an iPhone 11Pro, but not on an 12 or 13!
  • viewing HDR clips from Vimeo in the native Vimeo App
  • viewing HDR clips in the YouTube App on mobile devices.
  • viewing HDR clips from YouTube embedded on this website on certain Mac models (I assume it works with all the latest models that comes with Big Sur. It also works on a 2020 iMac 27″ and a 2018 MBP 15″ as well)
  • I can post HDR clips in LinkedIn and Twitter, but only SDR content is finally shown (automatic down-conversion of the format)
  • Instagram does not support HDR to my knowledge at all, but it is already accepting HDR videos from the new iPhone 12 generation. Theses videos are down converted to SDR automatically.

My interest in HDR was growing over the last years and in 2020 I got finally the chance to explore the topic further. Check out:
