Tests
Are the videos and animation in progress stopped when they leave the space seen by the user?
Precisions
The active content, animations, videos, sounds launched by the user may no longer be visible on the screen area presented to the user during navigation. Continuing to distribute this content becomes unnecessary and unnecessarily consumes resources, so it should be stopped.
Use Case
User tests cover behaviors of animated objects (Video, animations, ...) paused when out of visible area
