Adds a chapter title to a talking-head video that lands letter by letter in big type, each letter rising into place, with an optional number above. 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 wants a chapter title with more motion than a plain card (a short film, a vlog, a creative tutorial).

About this skill

You say

Spell out "What we tried" letter by letter as a chapter title in talk.mp4.

It said back

I added "What we tried" to talk.mp4 as a chapter title that appears one letter at a time, each letter rising into place. The check pass found no layout problems, and the settled frame in overlay-check.png reads cleanly.

  • Output: talk-graphics.mp4 in the working folder, 1920x1080 at 30 fps, 24.3 s long. Your original talk.mp4 is untouched.
  • Timing: The title starts as she says "we tried three things" and runs from 9.7 s to 12.3 s, about 2.6 s. It covers the whole frame while she keeps talking.
  • Look: studio, with a cool grey card, a big serif headline and a cobalt accent. I set the face position to [49, 30] from the face check.
  • Sound: Her audio is her own and unchanged.
  • Notes: There were no warnings or notes. I used only her words, with no number or kicker. The render used local Chrome and ffmpeg, so there was no model and no cost.
