Render animated SVGs into transparent PNG sequences for Adobe Stock video creation.
Records the canvas in real time via MediaRecorder — no intermediate frames or ZIP, and far lighter on memory. Output is opaque WebM/MP4 (no alpha channel), and export takes as long as the animation's actual duration. For the transparent ProRes4444 file Adobe Stock requires, use the PNG/ZIP export above.
Run these commands in the extracted ZIP folder to generate video files accepted by Adobe Stock.
