Add a chart with one row per track, added up across 2 or more videos, to compare them.

Before you start ​

  4. Click the settings button in its title bar. A panel opens.
  5. Select a value under Compare by. The bars redraw.

Check it worked ​

The card says which measure it uses, such as "Total occurrences per tier across 3 videos".

Compare by offers 2 measures.

  • Total occurrences adds up the marks of that track in every video.
  • Average coverage % takes the coverage of that track in each video, then takes the plain mean. A short video counts as much as a long one.

Each label ends with a count of videos, such as "2/3 videos". That tells you the track is missing from one video.

This module needs 2 videos or more. With one, the card says so.

The Excel sheet holds Tier, Category, Total occurrences, Total duration, Mean duration, Videos present and Avg coverage %.

Agreement is never part of this module. GRAPE MARS calculates Cohen's kappa for one video at a time.
