Claude makes beautiful HTML animations, but screen recording wrecks them with dropped frames, banded gradients, and a watermark. Framecast renders your animation frame-by-frame in a real browser engine into a clean, watermark-free MP4: YouTube 16:9, vertical 9:16, and square 1:1 from one drop. Works with CSS, GSAP, canvas, and SVG. Free preview, then $2.99 per video, no subscription.

What to expect from an ideal product

  1. Framecast renders Claude canvas animations frame-by-frame inside a real browser engine, eliminating the dropped frames and banded gradients that screen recording tools consistently produce on CSS, GSAP, SVG, and canvas-based HTML animations.
  2. One upload generates three export formats simultaneously β€” YouTube 16:9, vertical 9:16 for Reels and Shorts, and square 1:1 for feeds β€” so you never re-render the same animation twice for different platforms.
  3. Unlike OBS or Loom recordings, Framecast produces watermark-free MP4 files, making the output ready for client delivery, monetized channels, or portfolio use without post-processing in a video editor.
  4. The workflow is a single drag-and-drop: paste or upload the HTML file Claude generated, preview the render for free, then pay $2.99 once per video with no subscription or monthly seat fee attached.
  5. Framecast specifically solves the quality gap between what Claude previews in the browser and what screen capture actually records β€” preserving smooth gradients, animation timing, and sharp edges at the final pixel level.
