FEEL: Patient, actionable, specific, reassuring. Make the viewer able to reproduce the operation rather than admire the edit.
TEMPO: 3–12 s per meaningful step; hold 1.5–5 s after a result; extend for novice tasks; default sparse/medium. Compress waiting; preserve actual decision and verification steps [S16]. All numeric tempo/hold/proportion ranges here are heuristic starting points [H], not measured genre standards.
PREFER:
- State the observable goal before the action.
- Highlight the relevant control when it is named.
- Use deliberate cursor travel and pause on the target.
- Zoom for readability, then restore context.
- Leave a result visible long enough to verify.
- Keep accurate captions; avoid a second full transcript as a headline.
AVOID:
- Skipping the step a novice actually needs.
- Aimless cursor circles during explanation.
- Jumping UI state without revealing the cause.
- Ad-like cuts before the result can be checked.
- Tiny interface labels on phone-sized playback.
- Music or decoration competing with instruction.
TECHNIQUE MENU: Punch-in; Direct annotation; Ellipsis; Eye-trace handoff; Locked frame; Hold / release.
STRUCTURE HINT: flexible proportions, not scene slots.
- Goal/prerequisite: roughly 10–20%.
- Action plus verification: roughly 65–85%.
- Result/troubleshooting: roughly 5–20%.
