- Special thanks to Damon Lynch for 1DX Mark III HEIF and CR3 HDR samples.
- Thanks to Michel Lesoinne for R5 HEIF and CR3 HDR samples
- Thanks to Gordon Laing from Cameralabs for R6 HEIF
Canon released the 1DX Mark III camera with the ability to store HDR pictures in HEIF file format. Such pictures have 10 bits per color depth. HDR PQ must be enabled in settings. Filename extension is .HIF
HEIF container is ISO base file format (ISO/IEC 14496-12) and defined mainly in ISO/IEC 23008-12. Compression details (like HEVCDecoderConfigurationRecord) are defined in ISO/IEC 14496-15
Canon is using the "heix" major type, derived "grid" image for tiling and embeds "Exif" metadata (Exif, GPS and Makernotes) in "mdat" section.

Properties are numbered inside 'ipco' container, starting with 1. Property #1 is 'hvcC', property #2 is 'ispe', ... property #0x10 is 'irot'.
'ipma' links each item with their properties, for example dimension ('ispe') of main image (0x0001) is property #5 (ispe: v0 flags:000000 5472x3648) , because of 0x0001:0x04/0, 0x05/0, 0x06/1 association list.
