EOS 5D Mark IV – HDR movie shooting

If you’re shooting movies in HD on the EOS 5D Mark IV, you can capture them in HDR mode for expanded dynamic range to help avoid blowing out highlights. To set HDR movie shooting, the camera must be set to either FHD 29.97P IPB or FHD 25.00 IPB. If you have the camera set to ALL-I or 4K recording, then the HDR options will not be possible.
