Frequently asked questions
What is a green-screen reaction hook?
A green-screen reaction hook uses TikTok's green screen effect to put an artifact — a screenshot, headline, comment, or chart — behind you while you react to it on camera. It works by giving viewers instant context and borrowing the intrigue of whatever you're reacting to.
What should I put behind me in a green-screen hook?
Anything your audience already finds charged: a viral post, a surprising headline, a comment you got, a stat, or a chart. The artifact should be readable on a phone in a second and specific enough that viewers want to read it, which is what keeps them on the video.
How do I make a green-screen reaction hook stop the scroll?
Point at one detail instead of the whole image, crop tight so text is legible, and let your face carry the reaction before you explain. If you want a second opinion before posting, ReelTok can score the video from 0 to 100 and suggest a stronger opening line.
