How do you make a changelog or release video?

Kirocast makes shipping a video with every release sustainable: when the feature is ready, capture a fresh walkthrough, let automatic zoom and smart annotations add the polish, and export for your changelog, X, or Slack. It is the same app you use during the build to hand bug recordings to a coding agent, but each recording has one clear job. Personal is a one-time $39 launch purchase, normally $49. Kirocast runs on macOS 15 or later.

Why the release video stops happening

  • A changelog entry with a video gets read. A wall of bullet points gets skimmed.
  • But producing a video per release is a cost most teams abandon by the third week.
  • Feature clips go to small players: an X post, an embedded changelog, a Slack preview. An unzoomed capture of a full screen shows nothing at that size.
  • The feature shipped an hour ago. A video workflow that takes half a day means the announcement misses its moment.

What makes it sustainable

Fast enough to do every week

Record the flow once and the polish is applied from the recording itself. A release clip is minutes of work, which is the difference between a video changelog and an abandoned one.

The take you already made

While you build, hand bug recordings to your agent. When the feature is ready, capture it working, add the zoom and a background, and finish the changelog clip before you have written the entry.

Made for small players

Automatic zoom keeps the new feature large in the frame, so the clip reads clearly in an X timeline, a changelog embed, or a Slack preview.

Ships looking designed

Every clip lands on a real macOS wallpaper, your own image, or a custom gradient, with adjustable shadow, padding, and corners. A release note gets a considered-looking video without a designer in the loop.

One take, every surface

Export the same recording for the changelog, the tweet, and the team announcement. Files you own, sized for where they are going.

Common questions

How long should a changelog video be?
Fifteen to forty-five seconds. Show the feature doing its job once, with the state before and after. If it needs a minute of explanation, it needs a tutorial. Link one instead.
Can my agent write the release note from the recording?
It can get most of the way there. Every export can carry a written record of what happened in the clip - each click and its timing, the effects on screen, and a word-level transcript of what you said. Hand that to Claude Code or Cursor and ask for the changelog entry; you are editing a draft rather than starting from a blank one.
Can I export vertical clips for social?
Not yet. Vertical clip exports for social are on our roadmap.
