Production path · Explainers
Educational explainers
Facts first, pictures second. Manim, SVG, Remotion, and a TTS track. Opus can structure the lesson. A finished image is not a proof.
Step 1
Supply the source material
A paper, a syllabus, a manual, or your own notes. Addy Osmani's browser piece and LinearUncle's calculus lesson both rest on a subject the creator already knew.
Step 2
Separate picture, voice, and facts
One pass for diagrams, one for narration, one for a human or a second model to check units, formulas, and names. Do not let the voice track invent numbers.
Step 3
Show the working
For math and science, keep the code that produced the chart. If Opus claims it trained a model or ran a simulation, ask for the script and a checksum, or treat it as a diagram.

In short
- Can I skip fact-checking because the video looks right?
- No. Sampled frames cannot validate a derivative, a medical claim, or a legal timeline. Treat health, law, and finance as drafts until a person who knows the field reads them.
