1.2.7Extended Audio Description (Prerecorded)
Level AAAWhen the pauses in dialogue aren't long enough to fully describe the visuals, pause the video as needed to insert more detailed extended audio description. This matters for content dense with visual information, like instructional videos, where 1.2.5's standard audio description can't fit everything in. It's a Level AAA criterion that goes further than 1.2.5.
