How A Lightboard Works

No! You write normal and the video image is reversed so your viewers see it correctly. It sure is fun to try, though!

The lightboard glass is illuminated by a phenomenon called "total internal reflection" applied to low-iron glass. When you write on the glass, light will spill out at the markings to illuminate them. 

At a minimum: a lightboard, video camera, and fluorescent markers. Typically a microphone and backdrop are also used. The presenter will need adequate lighting to be clearly visible. A basic video editing software is recommended, even if just used to trim recordings.

Using A Lightboard

Use markers containing fluorescent coloring to get the brightest glow. Read more about markers.

Since the presenter is writing normally, the image must be flipped to appear correct to the viewer. This can be accomplished in one of 5 ways:

1. Use a pass through video converter like the Decimator MD-HX. This device can reverse a streaming video signal in real time. Inputs and outputs can be any combination of SDI and HDMI as desired. 

2. Many video editing programs can reverse the video image after recording is complete. Camtasia, Adobe Premiere (Pro or Elements), and Apple Final Cut Pro all have this capability. There are also programs that can flip the image in real time: Open Broadcaster Software, Wireframe, or the iGlasses app (Mac only).

3. Place a mirror at a 45 degree angle in front of the camera. Be sure to use a front surface type mirror for clarity. Typically users mount the camera and glass on a shelf on the far wall of the studio so alignment is well set/maintained and there isn't a vibration concern. 

4. Capture the video stream on a computer live using a video production program like OBS which has a built-in option to mirror the image while recording.  The setup process for capturing videos via OBS is detailed in our software image insertion guide. 

5. Some cameras have a built-in scan reverse feature to record or stream a reversed image. Cameras that have been verified to have this feature are Canon models XA10, XF105a, HFG10, and HFG20. The HFG20 was released January 2013 and is the newest camera with this feature. 

At a minimum you want to have a video camera which allows manual exposure controls. There are many options and a wide range of prices depending on other features and specifications you want. Please contact us if you'd like assistance with this.

Wipe writing off the glass with a dry paper towel. Periodically clean off remaining residue with a foaming glass cleaner and squeegee. For more details, please visit our full guide.

Yes, digital images can be merged with the video camera stream in real time using a hardware or software video switcher. View our complete guide on software image insertion. Add a confidence monitor near your camera to see the composite image. Contact us if you need help setting this up.

Yes! Remember the writing needs to be flipped to be visible, so the video camera stream needs to be broadcast to a monitor or projector even for local viewers. Users also interact with distant audiences live. Learn more in our Live Streaming Guide.
