Neither AppleTV nor AirPlay support HDR photos at this time, but they do support HDR video. And many social media sites similarly only support HDR for videos.

To help share your photos anywhere, Web Sharp Pro (WSP) v6.9.0 now lets Apple Silicon users export HDR photos as a video. It includes support to control timing, image order, cross fade transition styles, music, etc.

The workflow to create an HDR video from your photos is:

• Export your HDR images from WSP as JPG w/ gain map or 32-bit TIF.
• Go to WSP’s flyout menu (top right) and select “Create Video / HTML slideshow“
• Click the “Create HDR video” button (see it’s tooltips for the option to convert an existing HTML slideshow to video).
• Use the popup interface to edit and export the video. Options include:
  • You may drag and drop supported photos (jpg, avif, tif) or music files (mp4, mpa, wav) to add them.
  • You may drag and drop to change the sort order, or click <delete> to remove items.
  • In the music tab, you may click and drag the end points to trim the segment of the audio file to use.
  • There are options at the bottom for dimensions (use vertical video for social media, 4k landscape for YouTube, etc).
  • The gear icon at bottom includes options to control transitions, max HDR brightness, and HLG vs PQ encoding.

Note that support is not currently available for Windows or MacIntel computers.
