Teleprompter Mirror Mode: What It Is and When to Use It
Learn what teleprompter mirror mode does, how it works with beamsplitter rigs, and when you need it vs when you can skip it. Includes setup tips.
Quick Answer
Teleprompter mirror mode flips text horizontally so it reads normally when reflected by a beamsplitter glass in front of your camera. You only need mirror mode when using a hardware teleprompter rig with a beamsplitter. For software-only setups where you read directly from a screen, mirror mode is not needed and will make text unreadable.
What Is Mirror Mode?
Mirror mode is a display setting that reverses text horizontally — essentially creating a mirror image of your script. The letter "E" becomes its reflection. The word "Hello" becomes "olleH". Paragraphs run right-to-left instead of left-to-right.
At first glance, this seems useless. Why would you want unreadable text? The answer comes from how professional teleprompter hardware works.
How Beamsplitter Rigs Work
A beamsplitter teleprompter rig places a piece of semi-transparent glass at a 45-degree angle in front of your camera lens. Your screen (tablet, monitor, or dedicated display unit) sits below or above this glass, facing upward or downward.
Here's the physics: when light from your screen hits the glass at 45 degrees, it reflects toward you (the presenter) at eye level. The camera, positioned directly behind the glass, shoots through it — the glass is transparent enough that the camera sees straight through to your face.
The catch: when a flat image reflects off a mirror surface, it flips horizontally. Text that reads left-to-right on your screen appears backward in the reflection. This is the exact same phenomenon as reading text in a bathroom mirror.
Mirror mode pre-flips the text horizontally, so when it reflects off the beamsplitter glass, it flips back and reads normally.
When You Need Mirror Mode
Use mirror mode when:
- You're using a beamsplitter teleprompter rig (hardware rig with glass in front of the camera)
- You're using a dedicated professional teleprompter unit (Prompter People, Autocue, etc.)
- You've built a DIY rig with a mirror or glass panel
- Any setup where the text reflects before reaching your eyes
Do NOT use mirror mode when:
- You're reading directly from a tablet, laptop, or monitor placed near your camera
- Using a phone propped next to your camera
- Using a second monitor positioned behind or beside your camera
- Any setup where you read the screen directly without reflection
If you enable mirror mode without a beamsplitter, you'll just see backward text. It's an easy mistake — if your text suddenly looks like it's in a mirror, toggle mirror mode off.
How to Enable Mirror Mode in SyncVocal
In SyncVocal, mirror mode is available in the display settings panel. Look for the "Mirror" or "Flip Horizontal" toggle. Enabling it immediately reverses all text on screen.
SyncVocal also lets you combine mirror mode with other settings like font size, scrolling speed, and voice sync — so your rig setup and your script management stay in one place.
Vertical vs Horizontal Mirroring
Most teleprompter mirror modes flip text horizontally (left-right), which is what beamsplitter rigs require. Some apps also offer vertical flip (top-bottom), which is rarely needed but can be useful for unusual rig configurations where the screen faces downward into an upward-angled glass.
For 99% of setups, horizontal mirror mode is what you want.
Mirror Mode and Scrolling Direction
Here's a subtlety that trips people up: mirror mode only flips the visual display of the text. It does not reverse scrolling direction. Text still scrolls from bottom to top (or top to bottom, depending on your settings) — the reflection just makes the letters readable.
If your rig requires the screen to be upside down (some models position the screen below the glass facing upward, then tilt the device), you may need both horizontal mirror and vertical flip to make everything read correctly. Check your specific rig's documentation if the text still looks wrong after enabling mirror mode.
Does Mirror Mode Affect Video Recording?
No. Mirror mode only affects how the teleprompter text appears on your screen. It has no effect on your camera's recording. The camera shoots through the beamsplitter glass and captures your face normally — the reflected text is invisible to the camera because beamsplitter glass is calibrated to reflect at 45 degrees while transmitting straight-on light to the camera sensor.
DIY Mirror Setup Tips
Building your own teleprompter rig? A few practical notes:
- Use beamsplitter glass, not a regular mirror. A regular mirror reflects all light — the camera can't see through it. Beamsplitter glass (also sold as "teleprompter glass" or "half-silvered glass") reflects ~30% while transmitting ~70%, letting the camera see through.
- Block ambient light from behind the glass. Light leaking into the hood washes out the reflected text. Use a dark cloth or foam around the rig.
- The screen needs to be bright. The reflection is dimmer than the original screen. Use maximum brightness on your tablet and ensure the text color has strong contrast against the background.

If in doubt, turn mirror mode off. If the text looks normal (reads left-to-right correctly), keep it off. If the text is backward, turn it on.
