Make a Movie Trailer Reaction Video — Free, in Your Browser, No Editing
Reaction videos are one of the most-watched formats on the internet, and movie trailers are their natural habitat. But actually making one has always meant screen-recording hacks, editing apps, and syncing headaches. Today we're fixing that: Reactr's free reaction video maker is live for everyone.
It's called the Reactr Reaction Maker, it runs entirely in your browser, and the pitch is one sentence: watch a trailer, react on camera, and walk away with a vertical clip ready to post — free.
What it does
- Records while you watch. Pick a trailer, allow camera access, and your front camera records the whole session while the trailer plays. No screen-recording hacks, no sync work.
- Pause & Comment. Tap pause when you have a hot take — the trailer freezes but your camera keeps rolling, then you jump back in.
- Auto-edits your clip. When the trailer ends, Reactr builds a vertical 1080×1920 clip — trailer on top, your reaction below — with your best moments picked automatically. Prefer the whole ride? Download the full session too.
- Your @handle on the clip. Add your handle before you record and it rides the finished clip, so every share promotes your channel.
- Yours to post. Download it and post to TikTok, Reels, or Shorts. It's your content — and because campaigns are official studio campaigns, the clip you post is the sanctioned one.
- Delete anything, anytime. One tap permanently deletes your recording, and raw footage is wiped from our servers within 30 days regardless.
How to make your first trailer reaction
- Open reactr.gg/reactions on your phone and pick a trailer.
- Tap Record Your Reaction, agree to be recorded, and drop in your @handle.
- Tap Start Reaction — a 3-2-1 countdown, then the trailer rolls and so do you. Use Pause & Comment whenever you have something to say.
- When the trailer ends, wait under a minute while your clip is cut, then Download and post it from your camera roll.
Get the drop before everyone else
Trailer reactions are a speed game — the first wave gets the views. That's what the Reactor Roster is for: create a free account and we email you the moment a new trailer goes live on Reactr. Every clip you make is attributed to your account, and founding Roster members are first in line for the creator revenue program we're building with our studio and cinema advertising partners.
Why we built it
Reactr started as the reaction layer behind studio trailer campaigns — real fans, real first reactions, captured at the moment a trailer drops. The tool we built for those campaigns was too fun to keep behind closed doors. Opening it up to everyone means more reactions, more shared clips, and more fans discovering their next favorite film through someone else's face.
What's live right now
Three trailers are live for reactions today, with new ones added as they drop:
