How the Video Ad Maker Works
AnyTool builds short social video ads entirely in the browser. Scenes — product image or clip, logo, text, captions — are drawn onto a canvas sized to the chosen aspect ratio (9:16, 1:1, 4:5 or 16:9) with safe-area guides; a single deterministic draw(t) function powers both the live, scrubbable preview and the offline export. Frames are encoded with WebCodecs VideoEncoder (H.264 High) and an uploaded/chosen music track with AAC, muxed into a real, uploadable MP4 by a bundled muxer at roughly 10x real time, with a MediaRecorder fallback that can be converted to MP4 via the self-hosted ffmpeg engine. Output is watermark-free 1080p.
- Runs client-side — product assets are never uploaded
- Uploadable 1080p MP4 (H.264/AAC) for social ad managers
- 9:16, 1:1, 4:5 and 16:9 layouts with product/logo/music/captions
- Live preview = export; faster-than-real-time render
- WebM fallback + self-hosted MP4 conversion
- No watermark, no resolution cap, no sign-up
