Picture the render as a local last step, after the writing is done. Claude Opus 5.5 first produces a script and animation code for every frame, acting as a motion designer. The browser runs that code, draws the frames on your machine, and encodes the MP4 in the same place. This is not a video model returning filmed imagery. You can close the tab while it works. Most videos take one to five minutes.

Type stays pixel-sharp because it is drawn from that code, and the same is true of prices and logos. A pasted product link can supply the product name, the logo and the brand colours before drawing starts. Sketch applies a hand-drawn treatment. Motion drives kinetic typography and motion graphics. Music and timed sound effects are in the file, and up to six photos or a logo may be placed in it.

The encode is 1080p, without a watermark, and commercial use is allowed. Length is 10, 15, 20 or 30 seconds, in 16:9, 1:1 or 9:16. The chain does not use ffmpeg, Remotion, Claude Code or a Claude subscription. There is no 3D, no realistic people, no filmed footage and no games.
