HDR.toodee.de

This subdomain of toodee.de is a shortcut to check HDR media on Apple’s devices with EDR technology. It works on most recent Apple devices with the latest iOS/MacOS versions installed.
A quick test

Updated October 2023 – for the first time ever for me – it all works! Tested with macOS Sonoma 14.1. and iOS/iPadOS 17.1

View the image below and then click on the following clip to view a small animation that is encoded as an HDR signal. YouTube supports HDR content with browsers like Safari, Chrome and Firefox.
When the neon font appears a lot brighter, then your device can display HDR content that is embedded on this WordPress website.

In case it does not work and the neon font is not appearing brighter, try to view the clips directly on YouTube.com by clicking on the link in the video.

This is a standard dynamic range or so called SDR image.
This is a HDR encoded clip uploaded to YouTube.

Did it work for you? This is how it works for myself

This WordPress page sadly does not always work as intended, but the last round of tests was very promising.

  • On an iPhone 13 ProMax (with the freshly installed iOS 17.1) and Safari, the embedded YouTube clip is displayed in HDR. With earlier versions of iOS it only worked from within the YouTube app after I clicked the link.
  • On an iPadProXDR (iPadOS 17.1) with Safari the embedded YouTube clip shows HDR as well.
  • On an MBP (M1-Max with Sonoma 14.1) the embedded YouTube clip now shows HDR content with Safari (17.1), Google Chrome (118.0.x) and Firefox (119.0).
  • On my 2020 Intel 27″ iMac with Sonoma 14.1, the HDR clip plays without a problem in Safari and with Firefox. But somehow Google Chrome (119) does not show the embedded clip as HDR on the WordPress page and neither on the YouTube site.

I never had that consistent results, but it is also a long time ago that I tested this page. At the moment I removed nearly all my Vimeo links because I had to reorganise my uploaded content.

There are still obstacles

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 December 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 on iOS and also on Android devices.

Each time a new device or a new operation system comes out, I basically need to test everything again. Over the last years some features got enabled and disabled by Apple and it’s hard to keep track what works and what not.

Instagram supports HDR content in their Reels!
I uploaded some content in my Reels and now it is sometimes bright and sometimes not. Strange…but as far as I know only HLG encoded HDR content is supported at the moment.

TikTok supports HDR content – I am testing the upload possibilities at the moment on my TikTok account.

Here are two useful links to learn more about HDR content on the Mac and the EDR technology:

Explore HDR rendering with EDR from WWDC 2021.

More example clips can be found on the HDR-Gallery page.


My HDR articles

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:
