Ten mistakes people make filming a lesson they teach

You have taught this lesson in a room, to a person, more times than you can count, and it works. Then a camera goes on a tripod and what comes back is a video of somebody talking, with the part people needed happening just outside the frame or buried under the sound of the room.

The short version, if you read nothing else: light the thing you are teaching rather than the space it sits in, get a second angle on it, film the detail larger than you will show it, keep your voice and the demonstration on separate microphones, and say out loud where you are in the lesson. Most are free; the two that can cost, a second angle and a second microphone, are worth reaching for once the free ones are done, and all of them expire the moment you stop filming.

An honest general list of filming mistakes is shorter than this, because past a point it repeats itself. This one runs to ten because it covers one activity: a person filming a skill they teach.

Why does filming a lesson fail differently?

Because a lesson has two subjects and a talking head has one.

There is you, explaining, and the thing being demonstrated: the hands on the keyboard, the mouth making the sound, the cursor crossing the screen. Almost everything below is one of those two being served at the expense of the other. The camera, the light and the microphone all default to the person, because that is what they are sold to do, and the person is rarely what was searched for.

The mistakes post-production cannot fix sorts filming faults into the ones an edit can buy back and the ones that are simply absent. This list overlaps it and is wider, because much of what follows is recoverable and still not worth what recovering costs.

The ten, in the order they cost you

You light the room instead of the thing you are teaching

A lamp pointed at the space makes everything equally visible and nothing important, so the eye settles on your face and misses the fingering, the stitch or the cursor. On a music education partnership the artificial light was balanced on the angle covering the hands, because the hands were what was being taught. Where to put your light when you only have one gives you the position; what changes here is which subject it serves.

One angle on a skill that needs two

Your face explains and your hands demonstrate, and one camera has to choose between them second by second. Cutting between the two is also the cleanest way to shorten a long lesson without the join showing, though not the only one: b-roll, an insert, a screen recording or a punch-in can each cover a trim, and the two-angle version is simply the one that hides it best. How many cameras do you need? works out whether a second earns its place at your scale, and Giving every camera angle a job stops you buying a third that never does.

You film the detail at the size you will show it

If the close angle is framed exactly as it will appear in the finished video, nothing is held in reserve, and punching in later, which means enlarging part of a frame in the edit so it fills the screen, throws away resolution and goes visibly soft. Frame that angle tighter than feels necessary, or record it larger than you publish. Zooming in without going soft explains how much room you have.

The demonstration and your voice arrive on one microphone

One microphone between you and the instrument, the bench or the keyboard writes both into a single signal, and nobody can then turn one down without the other following. On the same music partnership the placement was redesigned so the instrument and the speech stopped bleeding into each other, which is a shoot change, not an edit one. Do you need more than one microphone? covers when a second is worth it, and Recording an instrument and a voice together is your exact case.

You film beside a classroom window across a long session

Daylight is the best free light you have and it refuses to hold still, so an hour of lesson filmed beside a window starts in one exposure and ends in another, and the halves stop cutting against each other. On that partnership the fix was not shutting the daylight out, it was adding a steady artificial source alongside it so the swing stopped mattering. Filming next to a window has the method.

Nothing is said out loud, so an hour of lesson cannot be searched

A long lesson arrives as one file named after the camera, and finding where you explained the third exercise means watching until you reach it. A cooking partner was asked to say the stage out loud while filming, on the recording rather than in a notebook, and hours of footage became scannable rather than watchable. What to say out loud while you film gives you the phrases, and the whole cost is remembering.

You teach over the demonstration at the same volume

When you talk across the thing you are demonstrating and both reach the viewer at the same level, neither lands: the words vanish into the sound of the work and the work vanishes under the words. Decide before you film which one carries each moment, then either stop talking over it or let the demonstration run alone. Mixing a lesson so people can follow it covers what a mix can do afterwards, which is less than deciding it at the shoot.

Wardrobe changes between sessions that belong to one series

Six lessons filmed across three afternoons in three different jumpers read as six unrelated videos rather than a course, and any lesson you later reshoot cannot be cut into its neighbours. Photograph what you are wearing on the first day and keep the photograph with the project files. Why wardrobe decides whether a series looks like one has the rest, and Resuming a shoot after a break covers the version inside a single day.

You open on your own name and logo

An animated title carrying your name spends the opening seconds telling the viewer something already on the channel, at the exact moment they are deciding whether this is the lesson they searched for. Start on the thing they came for, named or demonstrated, and put your identity somewhere it costs nothing. How long is a hook? sets the window, and Film three hooks, not one is what to do when you cannot tell which opening works.

The series has no repeatable form

Ten lessons that each start differently, run to a different length and stop in a different place give a viewer nothing to get used to, and nobody builds a habit around something with no shape. Settle the form once, how it opens, what the middle does, where it ends, and let the teaching vary inside. A formula beats a calendar makes the full argument, and Same day, same hour is its scheduling half.

What do you change before the next lesson?

Not all ten, and not in one sitting. Take the two that match what you teach: if the skill lives in the hands, the light and the second angle carry the video, and if it lives in what you say, microphone separation matters more than any camera decision.

Three items here can cost money: a second camera, a second microphone, a lamp if you do not own one. The other seven are position, timing and the decision to speak while the camera is running. Do those first, film one lesson and watch it back before buying. The list of faults you thought were equipment problems tends to get shorter.
