Green screen vs real b-roll — retention test

Green screen vs real b-roll — retention test
Tested the same explainer with green-screen images behind me vs cut-to actual b-roll clips. B-roll held ~12 points better at the midpoint.
— Green screen is fast and cheap, but static images = a slideshow, and people scroll slideshows.
— Where green screen won: reacting to a screenshot. The "I'm pointing at a thing" framing held attention fine.
Replace one green-screen image in your next edit with a 2-second moving clip. Watch the mid-roll drop shrink.
