How many cameras do you need?

Somebody told you that two cameras look more professional. They are not wrong, and it is still not a reason to buy one. A tutorial filmed on a single camera pointed at the right thing will beat the same tutorial cut between three cameras that were all aimed at the same person from slightly different chairs.

The test is not how many you own. It is whether you can finish this sentence about each one, before you press record: this camera is here so the viewer can see something. If the sentence trails off, that camera is going to cost you an afternoon in the edit and hand back nothing.

What does a second camera buy you?

Permission to cut.

Film yourself talking on one angle and every edit you make is visible. Your head shifts, your hands land somewhere else, the framing stays identical, and the viewer registers a joint in the video even if they could not name what they saw. That is a jump cut. Some channels use them deliberately and well. Most self-filmed tutorials are using them by accident, repeatedly, and wondering why the result feels stitched together.

You have three ways to hide one. A b-roll clip laid over the join, which works and requires you to have filmed b-roll. A punch-in, meaning a digital zoom into the same picture, which works and costs you a little sharpness every time. Or a second angle, which works, costs nothing per use, and can be done as many times as you like.

A second angle can cover a trim, show a detail, change emphasis or provide a backup. Decide which of those jobs the production needs.

On a music education partnership, a second angle was added on the speaker. Nothing else about the room changed and nothing else was bought. The videos stopped feeling static, because the edit could finally move.

When is one camera the right answer?

More often than the internet suggests.

If you sit in one place, talk to camera, demonstrate nothing physical and edit lightly, then one well positioned camera and a folder of short b-roll clips will cover almost every cut you need. The clips are free to film once and they work in every video afterwards. A second camera does not behave like that. It has to be charged, framed, focused, offloaded, synced and colour matched on every single shoot, for the rest of the series.

So the plain version: if your videos are you talking, and your edit currently feels loose, the cheapest improvement available is not a camera. It is ten short clips of your own hands doing ordinary things, filmed once, in the room you always film in.

What is the third camera for?

The thing you are teaching.

Your first two angles are both pointed at a person. The third is pointed at the subject: the pan, the hands on the keys, the joint being glued, the screen being drawn on. It is the only angle carrying information the other two cannot, which is why it is worth adding before a fourth of anything.

If what you teach is physical, this angle should probably have been your second one. A cook who films two flattering angles of their own face and none of the pan has spent the budget on the wrong half of the lesson.

How do you know an angle has no job?

Finish one edit and look at what you used.

Open the timeline of a video you have already published and work out roughly how much of it came from each camera. The angle you cut to twice, both times because the edit had gone quiet and you felt you ought to, is the angle with no job. It still cost you a card to offload, a clip to line up with the others, a colour match so the two pictures agree, and storage for the rest of its life.

An unused angle still took work, but a backup can earn its place without appearing in the final cut. Judge it by the risk or coverage it was meant to address.

A test before you buy

Film one video with what is already in the house.

Put your usual camera where it always goes. Put your phone on a shelf, a stack of books or a clamp, at a different height, to one side, framed tighter on your face. Record both. Then edit the video and count how many times you reached for the phone angle.

If the extra angle was useful, decide whether the phone can keep doing the job or whether another camera would improve the result enough to justify its cost. Check colour matching and workflow as part of that choice.

Where the count stops mattering

Two angles with clear jobs will carry a teaching channel for years, and most people reading this should stop there. The ones who need a third are teaching something their hands do, and they usually know it already, because they keep watching their own videos back and finding the moment where they had to say you cannot see this, but.

Our method. Filming a test video with an existing camera plus a phone on a second angle before buying anything, then counting how often the second angle is actually used in the finished edit, is this studio's own way of answering the question, not a fixed ratio.
