It was Thursday evening and I needed a teleprompter.
I was making a video about panoramic photography, and for the scenes where I speak directly into the camera I looked like a cross-eyed newscaster. While trying to read cue cards on a stand in front of the camera, my eyes were cast downward, and that looked odd.
To overcome this problem, I decided to read from the screen of my PowerBook instead. I figured that I could put the PowerBook display closer to the lens, and thus not appear to be looking down when looking at the camera.
But even with the text on the PowerBook screen, I still looked slightly downward when I wanted to look directly into the lens of the camera. A teleprompter was the solution, but there are no teleprompters in our area, and renting one from Los Angeles or San Francisco – both hundreds of miles away – was impractical and beyond my budget. I decided to build one.
Discipline Makes Successful Video
I am careful when making video productions to enforce a moviemaker’s discipline upon myself and my hired crew and helpers. This is a skill learned from experience. When one is making a video, attention to detail, continuity, and story are critical. I find that I can’t go back — ever — to shoot a fill-in scene; something will have changed, someone won’t be available, the light will be different — something will prevent success. Instead, I work to get it right the first time!
In the back of my sketchbook I keep a cardboard template with four windows cut to the proportion of a television screen. I use this to draw frames for my storyboards, and then I sketch ideas and stories into the frames. My sketchbook thus becomes the foundation of many of my projects. I had been working on the storyboard for this video for several months, and the story and scene ideas covered many pages of the book (see Figure 1).
Figure 1: The FileMaker database with my storyboard sketches forms the backbone of my script (top). On each page of the database I enter a description of the scene, the shot number, and the narration (detail. Bottom). Once it’s complete and sorted, I export the narration to text, which is then imported into InDesign to create the narration PDF document for the teleprompter.
From Sketchbook to Database
After deciding to use a teleprompter, I wanted to convert the sketches in my book to visual elements of a script database. I scanned the pages of the sketchbook, and then cropped the individual frame drawings into small photos that I stored in a folder. I then built a FileMaker template, and imported all the images into that database. FileMaker is very accommodating in this respect — it imported my entire folder of numbered images into the database automatically.
Once the sketches were imported, I added descriptions, scene and shot numbers (used to sort the story into chapters), and the narration text. This method allowed me to develop the text that I would read into the camera using the teleprompter. Using FileMaker’s sorting functions, I then generated a story that was in logical order with a narration that flows smoothly and which I could read easily. After sorting the script, I exported the script records into text, and then placed the resulting file in Adobe InDesign for my teleprompter needs.
Construction of the teleprompter
Having seen a number of commercial teleprompters over the years in television studios and at trade shows, I understood the concept. A teleprompter is a made of a sheet of glass suspended in front of the camera lens at a 45-degree angle. The glass reflects the image of a TV screen without affecting the light entering the lens. In the most sophisticated units, there is a controller — and an operator — to set the pace of the text scrolling on the screen. Mine is more primitive.
Figure 2: My homemade teleprompter has adjustable height (marked with a felt pen on the legs), a platform for the PowerBook, and a sheet of window glass mounted at a 45-degree angle in front of the lens. In the studio it works great. In a brightly-illuminated setting it would have to be draped with a black cloth to prevent ambient light from overpowering the image.
My prompter is nothing more than a sheet of window glass supported in a plywood frame in front of the camera at the correct angle (see Figure 3). I probably spent three hours cutting and building. Once it was finished, I set the PowerBook on it, and practiced reading the text as it paged-by. Without the sophistication of the scroll-speed controller, I use a PDF document, and I put a mouse with an extension cord on my knee to click when I want to change pages.
Figure 3: The PowerBook display is placed flat on the platform, and the glass reflects the image of the narration to the subject in front of the camera. The camera looks right through the glass, and is unaffected by the image on the computer.
Even with years of experience reading film negatives, handset type and such, my backwards-reading skills are limited. The image on my home-built teleprompter was — of course — backward. I tried to find a way to reverse the entire screen, but that was fruitless. I then placed my narration text into an InDesign document, formatted it with a style that would be very legible (white letters on a black background), then printed the file to disk as a .ps file with the image flipped horizontally (in the Output settings of InDesign’s Print window). Distilling this file into a PDF made the final document perfect for my reflecting teleprompter (see Figure 4). I was immediately reading with proper attention and eye movement — directly into the lens!
Figure 4: With the text flipped, I can read the narration from the PDF document displayed while looking directly into the lens of the video camera. With a mouse on an extension cable, I control the changing of the pages, and thus the pace of the narration. At first I thought the diminutive PowerBook would be too small to read easily, but have since learned that teleprompter screens are intentionally narrow to keep the reader’s eyes from moving too far back and forth while reading.
With my home-built teleprompter, the recording of the narration went smoothly, and now I have the device anytime I need it.
And I bet I’m the only person on my street with his own teleprompter!

Thank You so much! It’s exactly what I needed!
Thank’s God there are still people who willing to make they brain work beyond BestBuy !
Without You Human Race will die.
Thank You ,again!
Thanks for the idea. We are going to need a teleprompter very soon and I think this is just the solution we need. Thanks Mr. Lawler.

Yes, you will need special glass for a teleprompter. it is called beamsplitter glass it has special silver coating. the guys at https://www.prompt-it.com.au sell some of it or just google it and you will find a few places that sell.
check out the guys at http://www.prompt-it.com.au they have teleprompter very cheap for iphones and ipads also. i got one and it works super well.
Hey man just wanted to say thanks! I’ve been messing around with making my own telepromter too! and your tutorial is great.
Also wanted to say that instead of going through all that BS with flipping the text, and creating a PDF there are some awesome TelePrompter applications which let you set the size of the text, the text color, and text background as well as flipping the text so it reads the right way on the glass.
I am trying out one called.
Thanks again.
I have a questions.
There is a special glass for teleprompter?
Because I have a doble reflex with a common glass
Brian, check out Presentation Prompter for the Mac. As far as I can see it is excellent teleprompt software. Haven’t used it in anger yet, but has all the features I need.
good idea. i saw another instruction and a video on this site:
http://www.kai-renz.de/teleprompter/
but sadly it´s not in englisch… Anyway i like your version better – because it´s less work !
You Are a GENIUS!
Thanks a bunch for putting this together! Simply Brilliant!
I’m sharing this on a zillion social networks… thanks!
I love the resourcefulness of this whole thing, however, I think I’d think twice about bringing it to a professional set…
Kate Goldsworthy, Away With Words, http://www.awaywithwords.tv if you ever need a real prompter.
What a great setup! If wordworking is not your thing however, you might want to take a look at an even more simple setup utilizing cardboard boxes. You can download instructions at https://www.promptdog.com/downloads/diy_teleprompter.zip
I recently wrote a web-based teleprompter that will be perfect for this. I am putting in text flipping functionality in the next day or 2. Check it out at http://www.easyprompter.com It’s absolutely free and has more functionality than a lot of similar software.
Also, you can follow the development news on Twitter – http://www.twitter.com/EasyPrompter
COOOOOOOOOOOOOOOLLLLLLLLll
Never mind I bought a ‘poster frame’ from Staples and took out the plastic piece out of that which goes in front of the poster. It’s very very thin and works great.
What type of glass did you use? I found this article very helpful, but in the one I built I see a double image. It’s not blurry, rather I can see two of the image displayed on my screen about 1/16th of an inch apart. This is very hard on the eyes!
Any suggestions would be appreciated!
his is a great article and saved me hundreds of dollars. I constructed the prompter in about two days. The diagram in the article was easy to follow. I stabilized it a bit more than the diagram and it worked perfectly for a shoot I did that needed a prompter.
I found a great softwear called “Presentation Prompter,” under $100, put it on my laptop, controlled it with a mouse and it all worked perfectly.
The talent, who had never used a prompter before, had no trouble at all.
Thank you very much!
If your comfotable working with electronics:
Open an old TV or VGA monitor. (The kind with a CRT) On the back side of the picture tube you will find 2 coils of wire. One coil controlls the vertical sweep of the electron beam that draws the picture on the screen. The other controlls the horizontal. If you remove and reverse the wires leading to the horizontal coil you will in effect reverse the scanning on the screen. That will cause everything to be backwards. (If you do the same to the vertical coil the screen flips upside down.) It might be brighter than an LCD and there would be less hassle in preparing your prompts. Be carefull inside a TV or monitor though! Lots of high voltge in there.
Having worked in the television industry for years, I always found the specialized equipment a little over priced myself. Like the telepromter, a number of things could be made yourself if you just put your mind to it. Thanks for showing us how you did it! I also had a co-worker who built his own jib after studying one on a shoot.
Another suggestion on your design might be to add some black felt or cloth on the sides to shield it from lights, thus making the screen easier to read. Most of the telepromters I used also cover the area from the lens to the glass, giving you a black background behind the glass.
With the addition of a mirror parallel to the plate glass, you can set up your teleprompter in a more parascopic setup. This should allow you to view normally formatted text in the teleprompter without needing to reverse it, and would also allow the laptop to sit upright, making use of the keyboard more natural. I’d draw a sketch, but I have no place to put it, and I do not currently have the resources to construct a working prototype. I can be reached at bkofford at g mail dot com.
Love Brian’s article and it inspired me to discover that you can even make the teleprompter scroll.
Turn on Automaticaly Scroll from the View menu. Then, to control the speed hit the up or down arrows on the keyboard. You can even make it go BACKWARD!
