How to Make a Reaction Video for YouTube Shorts
A Shorts reaction video uses the same core idea as a normal reaction video, but the 9:16 frame changes the layout. You have less horizontal space, so the source, your face and any captions need to be arranged for a phone screen from the start.
Set the project to 9:16 before recording, stack the source and facecam or use a movable picture-in-picture window, keep the interesting moment visible, start quickly, balance the source under your voice and export the finished vertical video.
Start with 9:16, not a crop later
Designing the video vertically from the beginning is easier than taking a finished 16:9 reaction and trying to crop both faces into a narrow frame. KIPZO's vertical canvas lets you see the final composition before you press record.
Choose a vertical reaction layout
Stacked
Place the source on top and your reaction below, or reverse them. This keeps both areas wide enough to read on a phone.
Picture-in-picture
Let the source fill the vertical frame and place your face in a movable window. Keep it away from subtitles, faces and platform UI areas.
Host focus
If the Short is mainly your opinion, give yourself most of the frame and keep only the necessary source context visible.
Hook the viewer early
Short-form reaction videos should reach the reason for watching quickly. Start near the moment that triggers your response, or open with a brief line explaining what the viewer is about to see. Avoid a long camera setup, greeting or unrelated introduction.
Audio for Shorts
Phone viewers often listen on small speakers. Keep your voice clear and close, reduce the source enough to leave space for commentary, and test the finished video on a phone before posting. Captions can help comprehension, but they should not cover the important part of the source.
Reuse a longer reaction intelligently
If you turn a longer reaction into Shorts, choose moments that stand on their own. A short clip needs enough context for the reaction to make sense without the viewer seeing the entire long-form video first.
