What speed should a teleprompter scroll at?

Search for teleprompter speed and you will find words-per-minute figures quoted as if they were settings. They are not. A prompter does not scroll in words. It scrolls in distance, and how many words fit in that distance depends on things that have nothing to do with how fast you talk.

Why a number does not travel

Most prompter software measures speed as movement: pixels per second, lines per second, or an unlabelled slider from 1 to 10. Pixels per second is the most honest of the three, because it says what actually happens on the screen.

Now think about what a setting like 60 pixels per second means in words. Make the text bigger and fewer words fit on each line, so the same speed delivers fewer words per minute. Narrow the column and the same thing happens. Increase the line spacing and it happens again. Move the script to a different screen and the number can change meaning once more.

So a figure someone else swears by, copied into your setup, is almost meaningless. Their font, their column and their screen produced that number. Yours will not. Even your own number stops being right the day you change the text size, which you should do whenever you move the camera further away.

That is the first reason to stop looking for the magic value. The second is bigger.

The real problem is inside one script

Suppose you found the perfect speed for your setup. It would still be perfect only on average. Your pace changes inside a single take: slower on numbers and names, faster on lines you have said many times, stopped for a beat after a point you want to land. I went through those patterns, and the chasing and waiting they produce, in how to stop sounding like you're reading, so I will not repeat them here.

The short version is that a fixed scroll is a constant, and speech is not. Set it to your average and it is too fast in some places and too slow in others. Each adjustment fixes the part of the script you just struggled with and breaks a part you had no trouble with. You are trying to fit a curve with a single value.

None of this means a timed scroll is useless. Plenty of good videos are recorded with one. It means the goal is not the right speed. The goal is a speed that is wrong in the direction you can live with, plus a few habits that cover the rest.

Finding a starting speed in five minutes

If you are going to use a timed scroll, set it with your own voice, on your own setup, rather than from a figure on the internet.

1. Fix the layout first. Set the text size and column width you will actually record with. Speed depends on both, so any speed you choose before this is wasted.
2. Pick a paragraph you know well. Not the hardest part of the script, not the easiest. Something typical.
3. Read it aloud at the prompter, with no scroll. Scroll by hand and notice where your eye wants the text to be. Most people are comfortable with the line they are reading sitting at or just above the middle of the screen, with a few lines visible below it.
4. Turn the scroll on and adjust while reading. If the line you are reading drifts upward, it is too fast. If you keep running out of visible text below, it is too slow. Nudge in small steps until the line stays roughly where it started.
5. Then slow it down a little. Being slightly behind your natural pace is easier to recover from than being chased. When the text is a touch slow you can breathe, pause, or wait a beat. When it is a touch fast you compress, and compressing is what sounds like reading.

That last step is the one people skip. The speed that matches your average is not the speed you want. You want the speed of your comfortable sections, slightly under, so that the hard sections do not run away from you.

Making a fixed speed hurt less

Once you have a starting speed, most of the improvement comes from not trusting it blindly.

Keep a way to pause within reach. A key, a foot pedal, or a remote in your hand. A pause on the hard sentence is much better than slowing the whole script down for it. If your prompter lets you nudge the speed from your phone, the same applies: you can adjust between sections without walking back to the desk, which is what using your phone as a teleprompter remote is for.

Record in short sections. If each take is one section, you can set the speed per section. A slow, careful opening and a fast list of examples do not have to share a number.

Fix the script, not the speed. A sentence that keeps outrunning you is usually too long or too dense to say. Split it in two and the speed problem in that spot often disappears. How to format a script for a teleprompter covers the line breaks that help most.

Use a countdown. Starting to talk at the exact moment the text starts moving is harder than it sounds. A few seconds of countdown lets you settle your eyes on the first line before anything moves.

Re-check after any layout change. Bigger text, new screen, new distance from the camera: your old speed now means something different. Run the five-minute test again.

The alternative: no speed at all

Everything above is about living with a constant. The other option is to remove it: let the text move because you said the words, not because a clock ticked.

That is what Voice follow does in Mirrento. It listens through the Mac's own speech recognition, highlights the word you are on, and moves the view in blocks when you reach the end of what is in front of you, so the lines you are reading stay still while you read them. If you stop to think, nothing moves. If you trip and say a phrase again, it follows you back. There is no speed slider involved, and while Voice follow is on, the timed scroll is switched off entirely, so the two never fight.

This does not make the speed question irrelevant for everyone. Voice follow works best in a quiet room with one voice, as any speech recognition does. If you record somewhere noisy, or you want a deliberately even delivery, a timed scroll with the habits above is still a sensible choice. Both stay available, and you pick per take.

If you have spent more time adjusting a speed slider than you would like to admit, the 7-day trial is enough for a simple test. Run your five-minute speed test and record a paragraph with the timed scroll, then record the same paragraph with Voice follow. Count how many times you touched the slider or the pause key in each take.
