A green screen reaction is one screenshot, your face and one strong opinion. It's the format behind Jake's most viewed reel. Here's how to make one, and how to aim it at the right people.

Why this mattersYou don't have to explain the topic. The post behind you already did.

Jake's (@jakedavidsai) most viewed reel has 3.4M views. It's a green screen reaction. Behind him was a post about playing full video games for free in a browser tab. On top was one line of text: "I would of been cooked." That's the whole video.

It worked because each part had one job. The post did the explaining. His face did the feeling. The hook text was a feeling in 5 words that lots of people got right away. No studio, no script. Just a post people already cared about and an honest reaction. One warning, and it's a big one: that reel had nothing to do with his business. Step 4 covers why that matters.

1

Find a post your buyers already care about

Look for something your buyer would stop for even without you on it: a tweet, a news headline, a chart, a review, a price list, a rule change, a question someone posted in a local group. The cheat sheet below has ideas for different businesses.

Screenshot it. Save 3, so you have backups.

If you use a review or a post from a real person, blur their name and photo. React to the idea, not the person.

Set up the green screen

Instagram and TikTok both have a green screen effect in the camera. Search "green screen" in the effects, then pick your screenshot from your camera roll. It puts you on top of the picture.

Move yourself to a lower corner so the key line of the post stays easy to read. Zoom in on the screenshot so the one line that matters is big.

Nobody can read a full article on a phone. Crop to the one sentence you're reacting to.

React with one strong opinion, in under 30 seconds

Keep it to 4 beats:

  • Point: read the key line or point at it. 3 seconds.
  • Your take: one sentence some people would argue with.
  • Why: one real story or fact from your work.
  • What to do: tell the viewer what you'd do in their shoes.

Then add short hook text on top. Write it like a text to a friend, not a headline. Use this to draft it:

Copy this into ChatGPT or Claude
I'm making a green screen reaction video. I'll stand in front of this post: [DESCRIBE OR PASTE THE POST]
My business: [WHAT YOU DO]. My buyers: [WHO YOUR CUSTOMERS ARE].

Write me:
1. 5 options for the on-screen hook text. Under 8 words each. Sound like a text to a friend, not a headline.
2. My one strong opinion about this post, in one sentence. Something some people would disagree with.
3. A script under 30 seconds: read the key line, give my opinion, say why from my real experience (leave a blank like [MY STORY] for me to fill in), then tell the viewer what to do.
4. A one-line caption that ends with a question.

No hype words. Don't make up facts or numbers.

Aim it at buyers, not just views

Here's the honest part. Jake's 3.4M reel was about free browser games. Huge reach, but most of those viewers came for the games, not for anything he sells. An off-topic hit can fill your page with followers who will never buy, and it can blur who the app thinks your videos are for.

Before you film, ask one question: "If this got a million views, would the right people be watching?" If the answer is no, pick a different post. A smaller video watched by your buyers beats a giant one watched by nobody who'll ever call you.

An off-topic reaction for fun once in a while is fine. Just don't let one viral hit decide what your page is about.
