Notes on AI-drawn video and the timeline that directs it
Field notes from the team building Ruvil 2.1: what AI-drawn video is, how the model draws every frame in code, and how each section stays editable.
- Why We Draw Every Frame: The Problem With Text-to-Video, Image-to-Video, and Reference-to-Video — When 90% of a shot works and one detail is off, fixing that 10% should not force you to gamble with the 90% you want to keep. ()
- Ruvil 2.1 Explained: AI-Drawn Video With a .js Drawing Engine — How North Noir’s default AI-drawn video model works: one .js canvas drawing program per section, 30 fps deterministic renders, up to 3 vision review rounds, surgical Adjust edits, and multi-lane ElevenLabs sound. ()
- Ruvil 7.3 Explained: Hand-Drawn Frame-by-Frame Animation With AI — Inside North Noir’s selectable second model: a two-pass classical key-pose and non-linear breakdown pipeline, real cels from the Morning Shower section of our 9-to-7 Day in the Life film, timed ElevenLabs foley, and per-frame re-rolls on the frame strip. ()
- Ruvil 2.1 vs Ruvil 7.3: Which AI-Drawn Video Model Should You Use? — Ruvil 2.1 writes a deterministic .js drawing program at 30 fps edited via Adjust; Ruvil 7.3 draws each frame as its own 2D illustration cel with classical key-pose timing and per-frame re-rolls on the frame strip. ()
- One Sentence, Any AI Harness, Any Model: AI-Drawn Video With the North Noir CLI — Tell Claude Code, OpenCode, Cursor, Codex or any AI coding harness one sentence, and the model you already use draws a 1920×1080 video locally with the northnoir CLI. ()
- Sound Effects Models Ranked (2026): Prices, Tests and What We Use — Twelve sound-effects routes, the same three cues, real clips and spectrograms: what each one delivered, what it costs, and where sound effects fit in an AI-drawn video. ()
- Background Music Models Ranked (2026): Vocals, Instrumental and Prices — Instrumental and vocals leaderboards, filtered to the models we can actually run through ElevenLabs and fal — with prices, scores and our test generations. ()
- Software for AI-Drawn Video, and Video Made by Code (2026) — Which tools render video from code an AI writes, which generators return a finished clip, and where AI-drawn video made with North Noir fits between them. ()
- An AI Video Generator With Your Own API Key (BYOK) — How BYOK (bring your own key) works for AI-drawn video: what the model does, what your key pays for, and what North Noir still charges. ()
- AI-Drawn Video, Explained — AI-drawn video means every frame is drawn by an AI model in code — not a filter over footage, not a baked clip. Here is how it works and how you edit it. ()
