A captioned motion clip with local voiceover

Creator’s reproduction prompt

The creator published this complete prompt to reproduce the video. It is not a transcript of the original generation session. Required tools and inputs are listed below.

Make a 15-second 1080×1920 vertical clip with HyperFrames from this script: "I made this video without opening a video editor. I gave Claude Opus 5.5 one prompt. It wrote HTML, and HyperFrames rendered it to MP4. The captions, the voice, the motion. All local. Here is the exact recipe." Generate the voiceover locally, get word timestamps with npx hyperframes transcribe, and show big centered captions in the lower third, 3–6 words per group, highlighting each word as it is spoken. Above them, a code card whose lines fade in. Dark background, one warm accent. Run check, then render.

Complete instruction published by the creator to reproduce this video; the historical initial generation messages were not separately published. The full script is included. Requires Node.js 22+, FFmpeg and HyperFrames. The creator used the built-in macOS Samantha voice after Kokoro installation failed, and manually corrected one transcription word before rendering.
