Release-note clips for every shipped feature

Author a 30-second YAML when you ship. CaptureBeam compiles it into a 9:16 social clip, a 16:9 docs embed, and a 1:1 changelog GIF — same script, three deliverables. Pin to release tags so the right video ships with the right version.

Who this is for

DevRel, product marketing

Every release ships with a markdown changelog and a single screenshot. The growth team begs for video; engineering begs for time. Recording a polished walkthrough for every feature is a non-starter — until the recording can be a YAML the engineer who shipped the feature writes in five minutes.

The problem

Engineers ship a feature; nobody has time to record a polished video walkthrough; the release notes are text-only and the changelog reads like a patch log.

The fit

What CaptureBeam does for you

  • Each merged feature PR ships with a 30-second YAML
  • Render to a 16:9 docs embed, a 9:16 social clip, and a 1:1 changelog tile from one capture
  • Pin renders to the release tag — the right video ships with the right version
  • Posts as a PR comment automatically (PR demo bot integration on the roadmap)
