HTML to MP4について
HTML to MP4 conversion renders web animations, CSS effects, and interactive HTML compositions as professional video files. Upload an HTML file with CSS animations, JavaScript transitions, or HyperFrames data attributes and receive a shareable MP4 video.
Ideal for teams using HyperFrames (data-start, data-duration, data-track-index attributes) for AI-generated video pipelines. Configure output duration, frame rate, resolution, codec, and quality. Supports standard web animations including CSS @keyframes, transitions, and Web Animations API.
Motion designers export web-based animations for client presentations. Developers convert animated infographics to video for social media. Marketing teams render HTML email animations as video clips. AI pipelines generate HyperFrames HTML compositions and export them as distributable MP4 files.
Our renderer uses headless Chrome for pixel-accurate capture. Each frame is individually rendered at the specified frame rate and assembled by FFmpeg into a high-quality MP4. H.264 output is compatible with all major platforms including YouTube, Instagram, Twitter, and LinkedIn.

仕組み
Uses Puppeteer (headless Chrome) for frame-accurate HTML rendering. Each frame is captured as PNG at the configured frame rate, then encoded to MP4 via FFmpeg. Supports H.264, H.265, and VP9 codecs. HyperFrames data attributes (data-start, data-duration, data-track-index) are preserved during rendering.
