Adds an equation to a talking-head video: terms land as they are said, joined by + - x or =, and the result lands last in the accent. 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 how parts combine into a result (price x customers, hours x people).

About this skill

You say

In talk.mp4 show 12 people x 1 hour x 50 weeks = 600 hours as an equation.

It said back

I rendered talk-graphics.mp4 (1920×1080, 24.3 s, 30 fps) in the working folder. The equation reads 12 People × 1 Hours × 50 Weeks = 600 Hours a year. The sound is the speaker's, unchanged. I checked a still of the settled frame, not the rendered video.

The beat (full-frame, paper look, 4.9–10.7 s):

  • 12 People: lands on "12 people" (3.5 s).
  • × 1 Hours: lands on "1 hour".
  • × 50 Weeks: lands on "every Monday".
  • = 600 Hours a year: lands last, large in the tomato accent, on "600 hours".
