Recording in segments

If you might ever need a variant of this demo — for a different audience, a different length, a different language — record it as segments rather than as one continuous performance.

What makes a good segment

• Starts and ends at a stable screen state, so it can be reordered.
• Covers one idea, so it can be dropped without leaving a hole.
• Does not reference what came before it (“as we saw earlier” makes a segment non-portable).
• Is between fifteen and forty-five seconds of finished output.

The practical method

Keep recording continuously, but pause for three seconds between segments and say nothing. Those gaps become segment boundaries automatically, and you have not had to manage eleven separate files.
