HOW IT WORKS
Motion graphics, written as code.
Most AI video models paint frames pixel by pixel, which is why their text often smears. Opus 5.5 Video asks Claude to write the animation itself.
Brief
You describe the message, audience and feeling, and pick a style, format and length.
Plan and write
Claude plans three to six scenes and writes a program that draws every frame on a canvas.
Play
Your browser runs the program in an isolated player. Type is drawn at full resolution.
Change and keep
Ask for a change; Claude edits that part of the program. Download records the final version to MP4.
Why the text stays sharp
Every word is drawn with the browser's own text rendering, at the exact size and position the program chooses. Nothing is upscaled or guessed, so letters don't warp between frames.
The three styles
Motion — kinetic typography and bold shapes with snappy timing. Good for launches and announcements.
Sketch — hand-drawn strokes on warm paper that draw themselves on. Good for friendly, human brands.
Explainer — numbered steps, labeled diagrams and arrows with generous holds. Good for showing how something works.
Formats and lengths
16:9 for sites and YouTube, 9:16 for Reels, Shorts and TikTok, 1:1 for feeds. Videos are 10, 15, 20 or 30 seconds. The layout is computed for the format you choose rather than cropped.
Limits worth knowing
Videos are built from type, shapes and color — no footage, photos or uploaded logos yet, and no sound. Results vary between generations; if one misses, a short, specific change usually gets it there.
Write a better brief
Name the product, the one line viewers should remember, the colors, and the final words on screen. “Launch video for Lumen, a calm note app. Off-white paper, one orange accent, end on ‘Focus, finally.’” works far better than “make a cool video”. The prompt library has more starting points.
