Opus 5.5 Video Examples: 13 Code-Rendered Clips and Their Prompts Anthropic's Claude Opus 5.5 generates video by writing animation code — self-contained HTML files built on Canvas, SVG, CSS, GSAP, or Three.js that a headless browser renders frame by frame and ffmpeg encodes into MP4. An analysis of 475 public Opus 5.5 videos found roughly six in ten are motion graphics, four in five are 16:9 landscape, and the median length is 30 seconds, with Canvas used in 336 of them. Video is not mentioned on the Opus 5.5 announcement page; creators discovered the capability themselves, and a single prompt asking for a 15-second motion-graphics showreel has produced at least 90 distinct public videos. Claude Opus 5.5 makes video by writing the animation as code. A browser draws that code one frame at a time, and the frames get encoded into an MP4. So the output behaves like motion design work: crisp typography, exact colors, mocked-up interfaces, charts, and shape-to-shape transitions. Across 475 public Opus 5.5 videos, about six in ten are motion graphics, four in five are 16:9 landscape, and the median length is 30 seconds. Veo, Kling, and Seedance output pixels. Opus 5.5 outputs a self-contained HTML file built on Canvas, SVG, CSS, GSAP, or Three.js. A headless browser then renders that file one frame at a time https://huggingface.co/blog/karmen-beatapi/how-to-make-videos-with-claude-opus-5-5 , and ffmpeg encodes the captured frames https://claudevideo.org/ into the final file. Canvas shows up most often, in 336 of the 475 videos. SVG follows at 193 and Three.js at 141. Video isn't mentioned anywhere on the Opus 5.5 announcement page https://www.anthropic.com/claude-opus-5-5 ; creators worked out this use themselves. Treating video as code has three practical effects: Left to its defaults, Opus 5.5 drifts toward centered text over a gradient with every element fading in. That default is why so many of the first videos looked interchangeable https://x.com/rexan wong/status/2103707054108299437 . The good ones share four traits you can spot in seconds: From Stephan Livera's post https://x.com/stephanlivera/status/2103315922098470926 : 16,983 likes, 15 seconds, 16:9. The whole prompt fits on one line: make a dynamic 15-second motion graphics video that shows what an incredible motion designer you are, like it's your showreel for a résumé. go all out. Opus treated it as a portfolio piece, complete with a timecode HUD and chapter labels. One chapter plots six easing curves next to each other under the heading "Six ways to get from A to B." Another fills the frame with a tiling pattern on loop. A single word slams in at poster scale, and a red end card wraps it up. The prompt sets a goal, a 15-second length, and an ambition level, then leaves every content decision to the model. That makes it a good test of the model's taste and a poor fit for anything tied to your own brand. At least 90 public Opus 5.5 videos use this sentence or something close to it, among them reels from Ajith https://x.com/ajith io/status/2103449416325890146 4,057 likes and Leon Abboud https://x.com/leonabboud/status/2103576084499358051 , and each one looks different. We gave Opus 5.5 the same sentence: Our run of the same prompt: 15 seconds, 450 frames. Stephan's version leaned on easing curves and tiles. Ours started with a bouncing ball that bursts into the word "MOTION," then cut to a wave made of 2,304 dots and a ring of points morphing from circle to square to star. From Deedy Das's post https://x.com/deedydas/status/2102787937482252537 : 3,264 likes, 26 seconds. make a modern slick and punchy video for a modern startup that works on inference No company name was given, so Opus made one up: "muda," Japanese for waste. The film opens on a user stuck waiting 2.81 seconds for a response, shows a GPU cluster ramping to 94% utilization, and lands on a logo. Every scene has a small numbered label, the way keynote slides are chaptered. Nobody asked for a problem-product-proof-name arc; the model supplied it. How it was made: the single sentence above. It took Deedy about a minute and roughly $2. The product, every number on screen, and the brand name are fiction, so a real launch means feeding those in yourself. From Moritz Kremb's post https://x.com/moritzkremb/status/2103066071838466494 : 418 likes, 46 seconds. How it was made: Moritz told Opus to pick a product people know and pull its real assets from the internet. I want you to create a highly professional SaaS product launch video. Go and find some SaaS, preferably just one that people know, so it's easier to identify with it. Pick that, and then make sure to get actual assets and images and all of that stuff from the internet. Opus went with Notion and hit the standard launch-film beats: "Docs here. Chats there. Tasks everywhere." over drifting app icons, a rebuilt project board, a feature line paired with a chart, a strip of customer logos, and a closing card where a cursor clicks the call to action. Those real inputs are where the specificity comes from. For your own product, give it screenshots, your headline, and your feature list. Notion owns the brand and logos in this one, so it only works as a demo. From zero's post https://x.com/twoclipping/status/2103835273813496100 : 2,103 likes, 29 seconds, 1:1.
