When two people react together, framing has to allow for two different movements. One person may lean toward the camera while the other turns sideways or raises their hands. A shot that fits two still faces can become too tight as soon as the moment happens.
This guide is about composing and testing a shared camera shot in Fesi. It does not promise independent detection, tracking or separate reaction clips for each person.
Choose the shared frame before the event
Place the phone where both people can see whether they fit. Start with the positions you expect to use, then lean, turn and lift your hands as you naturally might. Check the most animated movement, not only the seated starting position.
If a hand or face leaves the frame, move the phone farther away or change the seating arrangement before recording. Avoid solving every framing problem with a tighter crop later: cropping cannot restore movement that was outside the original camera view.
Keep both people in useful light
A bright lamp behind one person can leave their face difficult to see while the other remains well lit. Review a short test with both people in place. If one face is much darker, adjust the light or seating rather than judging the setup from the brighter face alone.
Use light that remains steady during the event. A changing television image may illuminate two faces differently as people turn. The placement and lighting guide covers the basic setup.
Test capture with the actual arrangement
Start a short Reaction Mode test and review what it saves. Include a quiet response, a stronger expression and a moment when both people move. This is a practical test of your installed app, device and setup rather than a benchmark of multi-person detection.
Do not assume that fitting both people in the picture means Fesi will identify each person's response separately. Automatic capture can miss a moment. If a specific event is essential, plan for that uncertainty before the event begins and review the capture controls available on your version.
Check sound from both seats
Play the test at normal volume. Can you hear the quieter person as well as the louder one? A phone positioned close to one speaker can produce an unbalanced result. Move the phone or reduce distracting room sound and test again.
A shared microphone recording is not a promise of separate audio tracks. If you need to isolate voices afterward, do not assume a normal reaction file includes an independent track for each person. See the microphone guide for basic audio checks.
Choose the export after reviewing the movement
A vertical crop might suit one face but exclude the second person. A wider shape may preserve the interaction better. Play the full clip in your chosen output shape and check both people during the biggest movement.
Keep the original until you have verified the exported copy. Ask both people before sharing publicly, and choose an audience that matches what you agreed. The aspect-ratio guide and final playback checklist help complete that review.
