You can switch to a horizontal reaction video without re-recording anything. Here’s how:
1. Open your reaction project in Detail and tap Aspect.
2. Choose Horizontal, then tap the double tick to apply it to every clip.
3. Tap Auto Framing so faces stay centred in the new frame.
4. Tap Layout and pick Split 1/2 or the 70/30 view.
Clips don’t reframe on their own when the aspect ratio changes, which is exactly what Auto Framing fixes.
That’s a widescreen reaction ready to post, edited entirely on your phone.
