canvas-gen
BY @BAT — 13 DOWNLOADS — AUTOMATION
Generate Spotify Canvas / Apple Music Motion / IG Reel format vertical videos from a clip. Output is 9:16 (1080x1920), 3-9s, perfect-loop with seamless first-to-last frame match. Built-in modes — boomerang, ping-pong, fade-loop, freeze-extract — and auto-detects optimal loop length. Use when the user wants a Spotify Canvas, Apple Motion poster, IG Reel loop, vertical loop, or seamless 8s vertical video for streaming platforms.

Output spec
- 9:16 portrait, 1080x1920
- 30fps, libx264 CRF 22
- ~1-3MB at 8s — fits Canvas size limits
- Audio stripped (Canvas has no audio anyway)
Tips
- Pick a 1-2s window where the source has consistent motion vector
--startto seek into the source (default 0)- For Spotify, target 8s at 24fps (
--fps 24) for smaller file size
