How to record your first MeetingDouble loop.

A loop is the short clip MeetingDouble plays in Zoom, Meet, or Teams when you’re not at the desk. The quality of the loop is what separates “convincingly on the call” from “the screen froze again.” You only need to record it once.

1. Open the menubar popover

Click the MeetingDouble icon in the menubar — the small camera mark, top-right. The popover opens to a live preview of your webcam, the Record button, and the current loop slot.

If the preview is black, your webcam permission isn’t granted. Open System Settings → Privacy & Security → Camera, toggle MeetingDouble on, then quit and relaunch the app.

2. Set the scene

Sit where you will be sitting during real calls. Same chair, same window, same shirt you wear to work. The loop has to match the room you’ll be in when it plays — a clip recorded under tungsten light will look obviously wrong against a daylight call.

• Light from the front, not the side. Side light shifts every time clouds pass and exposes the seam.
• Plain wall or steady background. Anything moving (a clock, a fan, a roommate) breaks the loop.
• Frame yourself the same way Zoom will. Head-and-shoulders, eyes a third of the way down.

3. Hit Record and hold for 60 seconds

Click Record. A red countdown ring fills the lens preview. The app captures for 60 seconds by default — long enough that a 30-minute meeting rarely shows a repeat. You can change the length to 90 seconds in Settings → Loop.

What to do during recording:

• Neutral, slightly forward pose. Like you’re listening, not performing. Don’t nod. Don’t agree with anyone. Don’t smile too long.
• Blink at a normal rate. Two blinks every five seconds is human. Holding your eyes open reads as a frozen frame.
• Don’t move your head past the shoulder line. Big rotations don’t loop back. Tiny tilts within a 10-degree cone are fine.
• Keep your hands out of frame. A hand that appears at second 04 and disappears at second 53 is the easiest tell to spot.
• No phone, no eating, no obvious typing. The point is to look listening, not multitasking.

4. Review the seam

After recording, MeetingDouble plays the loop in preview with a five-frame crossfade at the seam. Watch it once. If your head is in a different position at frame 1 versus frame 1800, the crossfade is doing more work than it should and you’ll see a slight ghost. Re-record — it’s free, the old one stays until you delete it.

Where loops are saved

Each loop is a 1080p H.264 .mov file at:

~/Library/Application Support/dev.ogtay.meetingdouble/loops/

Files are named by capture timestamp — for example 2026-05-15T09-22-01_loop.mov. You can keep as many as you want; only the loop selected in Settings will play. Nothing is uploaded anywhere — see the privacy doc.

Managing loops in Settings

Open Settings → Loops. You see a list of every recording with a thumb, duration, capture date, and a label field. From here you can:

• Rename a loop (“daylight desk”, “lamp on”, “striped shirt”).
• Star a loop as the active one — that’s the one Zoom will see when you walk off.
• Reveal in Finder to copy a .mov off the machine if you want to back it up.
• Delete a loop. There is no undo; the file is rm’d immediately.

How many loops should I record?

Three is the sweet spot — one per lighting state of your room (morning, midday, evening), one in a different shirt, one in a heavier sweater for winter. MeetingDouble will rotate between starred loops if you have more than one selected, which kills any pattern detection on the other end of the call.
