Overview

Framecast converts HTML animations into clean, watermark-free MP4 video files. It accepts a single HTML file (which may include CSS, GSAP, canvas, or SVG animations) and renders it frame by frame on a virtual deterministic clock, eliminating the dropped frames and tearing common in real-time screen recording. The result is a broadcast-quality video up to 4K resolution, with precise frame capture.

Full Description ▼

A single HTML file can be processed into multiple aspect ratios simultaneously: 16:9 for YouTube, 9:16 for TikTok and Instagram Reels, and 1:1 for square feeds. This one-drop multi-format approach removes the need for separate exports. The service is designed specifically for animations created in tools like Claude, but works with any valid HTML animation.

Framecast is a pay-per-use SaaS; each video render costs $2.99 with no subscription. Users can preview a watermarked version for free. The tool is accessed via the web studio at app.framecastvideo.com, where files are uploaded and processed.
