Animated graphics with Remotion (optional)

Our video-overlay/captions path renders static PNGs composited by ffmpeg. When a job needs real motion design — eased entrances, staggered reveals, word-synced kinetic captions, animated lower-thirds, branded title cards, count-ups — author the graphic as a Remotion React component (every word/color/beat is a prop, animated over frame), render it to a transparent layer, then composite with our existing ffmpeg overlay. ffmpeg still owns the cut, audio, grade, and final encode; Remotion only authors the moving graphic.

⚠ Before using — it's optional and heavy

• Needs Node + npm and a Remotion project (the remotion/ scaffold in this repo). First render downloads a headless Chromium (~150–300 MB). This is a bigger dependency than the whole Python core — like the grok-video-edit vfx extra, it's off by default.
• Licensing: Remotion is free for individuals/small teams but companies above a small headcount need a paid seat license — verify before using under a company. (No API key, but a real license gate.)
• Render cost: frame-by-frame Chrome rendering; render the overlay at overlay size/duration only (seconds of a lower-third), never the whole video, to keep it fast.
• If the graphic is static or a simple fade → use video-overlay, not this.
