Mirror teleprompter text for your actual glass setup.
If the source screen looks backward but the reflection reads normally, the setup may already be correct. Judge the words in the glass from your speaking position. Making the source screen look normal can undo the flip you need.
Open the free readerStart with a card you cannot mistake for its reflection
A short, uneven test is easier to diagnose than a paragraph of familiar copy. Paste this into the reader, mount the screen using your hardware’s instructions, and look at it through the glass. Do not start scrolling yet.
TOP — one short line LEFT A B C 123 RIGHT BOTTOM — this line is deliberately longer
Check the letters, the order of LEFT and RIGHT, and which line appears at the top. Those checks distinguish a left-right reversal from a top-bottom inversion. A word such as “MOM” is a poor test because its symmetry can hide a mistake.
Change one axis at a time
| What you see in the glass | What to try |
|---|---|
| Everything reads correctly | Keep the current settings. Do not flip the text just because the source screen looks odd. |
| Left and right are reversed | Toggle horizontal mirroring, then read the test card again. |
| Top and bottom are inverted | Toggle vertical mirroring and recheck the labels and letters. |
| The whole card is rotated 180° | Check the display’s physical orientation first. Toggling both axes also produces a 180° text rotation. |
The two mirror buttons act independently. Write down the combination that works with this mounting position. Turning the device or changing its orientation is a reason to repeat the test, not to assume the old combination still applies.
Fit the reading area before changing the pace
Check the longest line at both edges of the glass. If it clips, increase the side margins or reduce the text size. Then check the first and last lines. A mirror setting changes orientation; it cannot bring text back inside a cropped reading area.
The Margins setting applies to each side. At 8%, the text has 84% of the reader’s width left; at 20%, it has 60%; at 40%, just 20%. The calculation is 100% minus twice the margin. On a 1,200-pixel reading area, those settings leave 1,008, 720 and 240 pixels respectively. A small slider change can make a big difference to line breaks.
Stand where you will deliver the script. Choose a text size you can read without leaning toward the glass. If the reflection is difficult to see, compare a brighter source screen and a darker reading background under the actual lighting. Follow the hardware maker’s advice for the screen and glass rather than relying on a universal brightness number.
Paused editing briefly changes the source view
In this reader, clicking paused script text makes it editable. The source text temporarily returns to its normal orientation so typing is usable, and the reading guide hides. Click outside the text or press Play to return to the reading layout and restore the mirror settings.
Check the reflection after leaving text editing. An unmirrored source while you are typing is not evidence that the saved mirror preference has disappeared. Text mirroring is also separate from any mirrored camera preview.
Finish with moving text and a recorded sample
Scroll a few lines through the reading area and pause. Confirm that the words remain readable from your speaking position. Record a short sample with the camera behind the glass, then watch the actual recording for gaze direction, framing and any part of the hardware entering the shot.
Once the physical setup is settled, the YouTube guide explains how to pause for demonstrations and pick up the next camera line. Export a TXT copy of the finished script before switching devices; browser saving does not transfer it to the mounted screen automatically.
