This tutorial explains how to analyze an HDR content and export the HDR report.

If the content is in Dolby Vision, refers to the related section in the User Manual.

2. Set the active area

The HDR metadata should not include the blanking, that's why properly setting the active area is crucial. We have to respect the aspect ratio of the content, if we don't want to include the letterbox (e.g a scope format fitted in a HD frame).

  1. To define the active area, go to Composition Settings / FORMAT to setup the Active Area Aspect:
Active Area in Composition Settings

For convenience, the Canvas aspect ratio is displayed in the section Format above Active Area.

  1. Pressing ALT+B  we can check the active area thanks to the green frame guide:
Guide for active Area



3. Launch the analyze

  1. Press F6 to call the Composition Analysis tool.
  2. Select HDR Statistics as type of analysis then define the color space of your content from the dedicated drop-down menu. 
  3. Click on the Analyze button to launch the analysis:
