Video Generation
An image is a 2-D tensor. A video is a 3-D one. The theory is the same; the compute is 10-100x harder. OpenAI's Sora (Feb 2024) proved it was possible. By 2026 Veo 2, Kling 1.5, Runway Gen-3, Pika 2.0, and WAN 2.2 ship production video from text at 1080p — and the open-weights stack (CogVideoX, HunyuanVideo, Mochi-1, WAN 2.2) is 12 months behind.
Visual edition planned
This lesson isn’t interactive yet.
It is part of the curriculum and will get the same treatment as Phase 1 — a visual cover, hands-on labs, derivations with numeric checks and a quiz. Until then, the original lesson is the best place to read it:
