Post sharing a prompt for a startup launch video, with the playable result missing with Claude Opus

Originally posted by @iammxfschr on X · posted Sep 25, 2026 · curated by MotionHunt, updated Oct 16, 2026

In short

A short launch-style video generated from a one-line prompt asking for a modern, slick, punchy video for a modern inference startup. The author says the result arrived as a ".cinfig" file that played as video, and they then asked for trendy music to be added. Length and aspect ratio are not stated.

Prompt

From the author's post

make a modern slick and punchy video for a modern startup that works on inference

How it was made

The author says the video started from a single prompt in a chat conversation, which they wrote in German and English. The post frames the result around Opus 5.5, but the author does not explicitly name the model, the tool used to control or render it, or any time or cost. The output was a .cinfig file the author could play as video, and music was requested afterward.

Tools: Claude Opus

Why it works

The prompt sets a clear style brief (modern, slick, punchy) and a clear subject (a modern inference startup), which gives the output a defined tone.
