Adds a sequence diagram to a talking-head video: two to four actors with a lane each, and the messages that pass between them drawn as labelled arrows in order as they are said. Timed to the words they say, on their own footage, with their sound kept; 16:9, 9:16, 1:1 or 4:5. Renders locally with Chrome and ffmpeg: no video model, no key and no cost. Use when someone explains who sends what to whom, step by step (how a payment goes through, how an order reaches the kitchen).

About this skill

You say

In talk.mp4 show how a blocker goes from a teammate to the board to the 15-minute call as lanes.

It said back

I rendered talk-graphics.mp4 (1920x1080, 30 fps, 24.3 s), and the speaker's sound is unchanged. It's in the working folder next to talk.mp4. The --check pass reported no layout problems and I looked at the settled frame. I didn't watch the rendered video itself.

The beat (lanes, full frame, 11.2–17.6 s, paper look):

  • Lanes: Teammate, Shared board, 15-minute call.
  • Arrow 1: Teammate → Shared board, "Written update". It lands on "Written updates on Friday".
  • Arrow 2: Shared board → 15-minute call, "Something is stuck". It lands on "only when something is stuck".
  • End: The beat stays up until she says "stuck".

What do I get from Message Sequence Lanes?

Your video with the overlay timed to the words, sound kept. Each actor stands at the top of a lane; as they explain each step, an arrow passes from one lane to another with what is sent. 16:9, 9:16, 1:1 or 4:5.
