Workflow
- Pick one lesson: One idea per clip. If the lesson needs two ideas, it needs two clips.
- Cut to the demonstration: Skip the introduction and recap. (Long to Reels)
- Add step-numbered captions: Use the same style across the course. (Burn-in)
- Reframe to 9:16: Zoom the action; let the narration stay in. (Reframe)
- Export for the target platform: 9:16 for short-form; 16:9 if YouTube long-form gets the same lesson. (Content Pack)
Pitfalls to avoid
- Lesson doesn't fit in 60 seconds - split into 2 clips
- Captions cover the diagram
- Intro that names the course instead of teaching
