01What shipped

HN Claude/Codex/Fable reports: We made our launch video with Claude Code (and open-sourced the tool). Article URL: https://kiln.tech/blog/we_made_our_launch_video_in_claude_code Comments URL: https://news.ycombinator.com/item?id=49869834 Points: 1 # Comments: 0

Along the way we built and open-sourced the tool we wished we'd had: videowright. Animated SVG, Lottie, React, Svelte, anything that renders in a browser.

02What improved

Speech-to-text gets word-level timestamps; the agent fits video beats to them. I wrote the script, Claude wrote the animations, we iterated in chat, we previewed in a browser.

03What you gain

Screen-captured the dev server at 60fps, added a voice-over in post, shipped. See the full write-up from HN Claude/Codex/Fable via the source link for quotes and complete context.

Claude is good at web tech, which means Claude is good at video Animated explainer videos are mostly HTML, CSS, SVG, and timing. The first version Claude writes isn't your finished video, but it's not embarrassing either.

04How to get it

The same way Claude can write a first version of a landing page that doesn't embarrass you. The UI is live, not a mock, because the agent already understands web components.

05What to watch next

You don't need motion graphics software for overlays For a short founder talking-head clip we wanted real motion graphics on top. See the full write-up from HN Claude/Codex/Fable via the source link for quotes and complete context.
