Practising is mostly about timing. Reading each video aloud tells you how long it actually runs — so you can right-size it before you ever film.
Each video should cover one concept. Aim for 2–6 minutes. If a video runs long, that’s usually a sign it’s really two concepts — split it out differently. The exception is a long derivation or worked example: keep it together rather than chopping it, and just try to max out around 10 minutes.
Slow is clear. Reading your clips aloud a few times settles your pace so it doesn’t rush on the day.
Where it fits, a light touch of humour makes a concept land and keeps students with you. It’s always welcome.
Imagine a single student across the desk and teach them, not a camera. It instantly reads warmer and more natural.
No need to apologise or push through. Stop, take a breath, and re-run the sentence from the top — we cut the fumble out in the edit.
Know your material well enough that the teleprompter is a safety net, not a script. Read each clip aloud beforehand; your own words always sound most natural.
