A free Skill that turns a changelog or release-notes Markdown file into a 45 to 60 second square video. It cuts the list down to a few themes, mocks the actual UI acting out each change, writes a two-layer script for voice-over and captions, and builds a HyperFrames project on a fixed scaffold with brand fonts, a background loop and music.

About this Skill
You say
/changelog-video Turn this week's changelog into a square changelog video for our smart-home app: themes are scenes that run at sunset and a weekly energy report. Use our coral accent.
Release notes nobody reads become a video people watch. Changelog Video takes your weekly changelog, keeps the few changes that matter, and shows each one as an animated mock of the real interface doing the new thing, never as bullet points. It writes the voice-over, keeps captions in standard spelling, and builds everything on one scaffold so every week looks like the same show.
How it works
- Cut: it reads the changelog, keeps three or four themes and at most three items each, ordered from headline feature to fixes.
- Route: each theme gets a visual: a mock of your UI, an analogue, a terminal, or a checklist as the last resort.
- Script: it writes spoken and display versions of every line, so terms read correctly aloud and appear correctly in captions.
- Voice: it records the voice-over with word timings (HeyGen's TTS in the original setup, or any tool that returns timestamps).
- Build: it fills the master scaffold scene by scene, places the caption rail and checks frames before rendering.
Tips
- Feed it the raw changelog; the editing is its job.
- Replace the bundled background loop and music with your brand's.
- Keep one accent colour moment per scene; it is what makes each change pop.
- The square format suits LinkedIn, X and Discord; ask for 16:9 if it goes on YouTube.
Open source
This Skill is part of the HyperFrames repository. Made by HeyGen and the HyperFrames contributors (heygen-com/hyperframes) and shared under the Apache License 2.0. Reelity replaced its commercial fonts with the open-source Geist and Geist Mono and added a background loop and a CC0 music track, because the repository keeps those files in Git LFS.
What you need before you start
- You bring
- Your changelog as Markdown, your brand colours and, for voice-over, a text-to-speech tool that returns word timings.
- Dependencies
- Node.js 22 or newer — required · FFmpeg — required
- Outside costs
- None for HyperFrames. The original voice-over step uses HeyGen's text-to-speech, which needs a HeyGen account; you can use another voice tool instead.

FAQ
Do I need HeyGen?
The original Skill records the voice-over with HeyGen's text-to-speech. Any tool that gives you an MP3 and word timestamps works, and it can also make a captions-and-music version with no voice.
Can it use my fonts?
Yes. The package uses the open-source Geist family; swap the files in assets/fonts and the names in the scaffold for your brand fonts.
Why is it free?
It is an open-source Skill by HeyGen and the HyperFrames contributors. We list it as it is, with a sample made by running it on one of our house brands, Solenne.
