The best explanation you ever give of a technique is usually the one you improvise in front of a class. You build the file live, you talk through why you are reaching for one tool instead of another, you say something useful when it nearly goes wrong — and then class ends and all of that exists for exactly as long as the people in the room remember it. What gets posted afterward is a tidied-up set of steps, which is a much thinner thing.

So I tried recording the demo instead. Not a produced tutorial with a script and a clean take. Just the live demo, screen and voice, while doing the thing I was going to do anyway, and then letting software turn the recording into text and stills.

A four-and-a-half minute Illustrator demo became a finished, published Canvas page. The recording was 15.5 MB. Transcription took about thirty seconds, running locally — no audio left the machine. Twelve stills came out; four were used.

The part I found most interesting is what the tooling could not do. One extracted frame showed a green circle at the exact moment the step says to make it cyan, because it caught me mid-drag between two colors. Nothing in the transcript flags that. Catching it meant looking at the picture and asking whether it showed what the sentence claimed, which is editorial judgment rather than transcription. The same pass cut the false starts and a stretch where I was losing an argument with the color sliders.

That is the honest shape of it. The tooling removes transcription, screenshotting and formatting, which is most of the tedium. It does not remove deciding what is worth teaching, or checking that a picture shows what the words say. If anything it makes that judgment matter more, because the raw material now arrives much faster than it used to.

What changes is the economics. A produced tutorial has to earn its production cost, so you only build them for things you teach many times. A captured demo costs nothing beyond pressing record, so it is worth capturing everything and deciding later what deserves to become a page.
