How to record a reaction video with front and back cameras (picture-in-picture, one file)

1. Why picture-in-picture fits reaction videos

A reaction video only makes sense if the scene in front of you (back camera) and your reaction to it (front camera) are in the same frame. You could film two separate clips and merge them in an editor, but capturing them as picture-in-picture at record time gives you a finished file with no editing step.

2. Before you hit record

Check two things before recording.

• Confirm your phone supports concurrent cameras (both previews should update live on the camera screen)
• Allow microphone access if you want sound in the recording

3. If your phone doesn't support concurrent cameras

Phones that can't run two cameras at once can't record dual video at all — that's a hardware limit, not an app restriction, since keeping both camera streams open for a whole clip isn't possible on that hardware. Those phones can still use photo mode (back photo, then front, merged), just not video.

4. Recording and saving

On a supported phone, watch the live picture-in-picture preview and tap record. When you stop, everything saves as one video file, with sound included if the microphone was allowed.

You can swap which camera is the main (large) view mid-recording with one tap, so you can switch to the front camera right when the reaction happens.

5. In Bothshot

On phones with concurrent camera support, Bothshot records a picture-in-picture reaction video as a single file. It lands in a dedicated album for one-tap sharing and also saves to your phone's gallery under Movies/Bothshot. No account, nothing uploaded.
