Teleprompter mirror mode: using an iPhone in a beam-splitter rig
In a beam-splitter rig the phone lies under a half-silvered glass set at 45 degrees in front of the camera lens. The camera films through the glass and you read the script reflected on it, straight down the lens. The reflection reverses the text left to right, so turn on mirror in Teleprompter to flip it back; use flip as well if your rig mounts the phone upside down. Both are free.
Mirror, flip, or neither
Set them to match the rig, not by guesswork.
| Setup | Mirror | Flip |
|---|---|---|
| Reading straight from the phone | Off | Off |
| Glass rig, phone face up below the glass | On | Off |
| Rig that mounts the phone upside down | On | On |
| Script on a monitor over AirPlay or HDMI | Depends on the monitor's rig | Depends on the rig |
Text settings that read well off glass
Glass loses contrast and you read from further away than a phone in your hand. Raise the font size, increase line spacing, narrow the margins so lines stay short, and use light text on a dark background at full opacity. All of these are adjustable, along with colours and background opacity. A reading guide line helps you hold your place at a distance.
Driving it from a distance
Once the phone is in the rig you cannot touch it. Control the script with a clicker, pedal, keyboard or game controller — M toggles the mirror from a keyboard — as described in remote and pedal control. For voice-paced reads see voice scrolling.
What this cannot do
- The rig itself (glass, hood, mounting) is hardware the app does not provide.
- Reflection quality depends on the glass; cheap acrylic can show a double image.
- iPhone only, iOS 16 or later.
