How I Animate Math with DaVinci Resolve.

From a channel Lumen includes in full: Every sampled transcript is a structured mathematical explanation: olympiad solutions, proofs, tiling and lattice arguments, plus a software tutorial on making math animations. Viewers are repeatedly asked to pause and attempt problems. Titles are descriptive puzzle statements with at most mild curiosity framing and no caps or sensationalism. The creator is a Cambridge maths undergraduate and 3Blue1Brown animator, and the channel shows no entertainment-first, promotional or filler uploads.

A 12-minute video from PolyaMath's catalogue; the title names its topic.
