What research says

Instructional design research strongly supports shorter videos and breaking long ones into meaningful chunks (a systematic review of instructional video design). A study comparing short, medium and long videos found no difference in how much students felt they learned, though they concentrated better on short ones (a 2024 study on video length).

Where Shorts help

A single quick fix: a keyboard shortcut, a cooking trick, a form cue.

Where long videos help

Get the best of both

Keep Shorts for a set time, and close the app after.
