Can Claude Opus 5.5 generate a video by itself?
Not as pixels. Anthropic's documentation lists text and image input and text output for its current models and states that Claude cannot generate, produce or edit images. Every video on this page was either rendered from code Opus 5.5 wrote (HTML and Canvas, Remotion, HyperFrames, Manim, Three.js, Blender Python and so on) by a headless browser or renderer plus FFmpeg, or made by video models it directed through an API and then cut together. In a chat window with no shell you get the animation as an HTML page you can open and screen-record; producing an MP4 directly needs an agent environment that can run commands.
Can Opus 5.5 watch a video I give it?
No. It has no video input, and an animated GIF is read as its first frame only. The workaround every editing case here uses is to have it extract frames (and transcribe the audio) with FFmpeg and look at those stills. It reviews its own renders the same way.
Do the "one prompt" videos really come from one sentence?
Some do: the 15-second showreel prompt is a single sentence. Many of the widely shared cases ran on briefs of thousands of characters, with skills installed in advance, API keys for voice, music or video models, and runs of one to twelve hours, sometimes with dozens of review rounds. Costs on these cards are what each creator reported, from about $2 for a 26-second launch clip to around $400 of credits across 33 versions of a product trailer. Every card is marked as an original prompt, our summary of a method the creator described, or a case whose prompt was never published.
What do I need installed to reproduce these?
For an MP4: an agent that can run commands (Claude Code or a similar tool), Node.js, Playwright or another headless Chromium, and FFmpeg. The UI-motion templates also use Python with numpy to analyse the soundtrack; Manim cases need Manim and LaTeX; Blender cases need Blender; music-video and director cases usually need API keys for voice, music or video models.
Which approach should I start with?
For a product clip or a UI animation, start with the single-HTML route or a framework such as Remotion; both are on this page with full prompts. For a lesson, use Manim. For anything with real people, natural motion or physics, let Opus direct a video model and keep a cost gate in the brief. For footage you already shot, use the editing route and expect to make the pacing calls yourself.
How much does Opus 5.5 cost for this on apimodels.app?
$2.40 per 1M input tokens and $12 per 1M output tokens (Anthropic lists $4 / $20), billed per token with failed calls free, through /v1/messages or the OpenAI-compatible /v1/chat/completions, so Claude Code and other Anthropic-compatible agents connect with a base URL and a key. Video work is output-heavy: one creator's Blender test wrote about 200K output tokens, roughly $2.40 of output at our rate. Our own single-HTML test through apimodels.app was one call of 31,786 output tokens, billed $0.368, for a 12-second 1280x720 promo. If Opus directs video models, those calls are billed separately per model; Seedance 2.5, MiniMax H3, Kling V3 and Wan 3.0 run under the same key.
Can I reuse these prompts and videos?
The videos belong to their creators. Clips from X play straight from X's own servers, every card links to the original post, and we do not host or re-upload any of them. Prompts are quoted with credit and a link: several authors explicitly invited reuse, others simply published theirs, so check the post before using one commercially. Some cases use third-party music, pay homage to an existing film or show real people, and each of those cards names the source material. If you made one of these and want the card removed or the credit corrected, email us.
