How the Video Intro Maker Works
AnyTool generates animated video intros entirely in the browser. A parametric, frame-indexed animation system draws each template (logo reveal, animated title) onto a canvas; an uploaded logo (PNG/SVG/JPG) is rasterized and drawn into the same pipeline so the export matches the preview pixel-for-pixel. Frames are encoded with WebCodecs VideoEncoder (H.264 High at 1080p) and muxed into a real MP4 by a bundled muxer — roughly 5-10x faster than real time — with a MediaRecorder WebM fallback that can be converted to MP4 via the self-hosted ffmpeg engine. A live, scrubbable preview plays the actual animation, and 16:9, 9:16 and 1:1 aspect ratios are supported.
- Runs client-side — logo and assets are never uploaded
- Animated 1080p MP4 via WebCodecs, faster than real time
- Logo + text drawn into the same canvas as the preview
- Live scrubbable preview that equals the export
- 16:9, 9:16 and 1:1 aspect ratios
- No watermark, no resolution cap, no sign-up
