The project owner reported that Synthesia generated the project scene by scene before rendering.
Review
Visual explanation finding
The output is polished as an avatar presentation, but generic physics imagery, headings, and bullet points do not show how superposition works. The score remains provisional because no blinded multi-reviewer sheet exists.
Review status: provisional manual. See the visual-scoring rubric →
What the output shows
The avatar, typography, and scene changes are clean. The teaching mechanism is weak: the video names superposition but never constructs a visual model of multiple states, measurement, or collapse.

Pricing basis
The ranking uses the more conservative FAQ calculation: $264 per year ÷ 120 included minutes = $2.20 per minute. The same page's checkout-linked card implies $1.40 per minute, so both published figures remain disclosed.
