Adds a ratio to a talking-head video: a bar split between two sides and a big "3 : 1" set beside it, as they say how the two compare. 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 says how two things compare as a ratio (editing to filming, effort to reward).

About this skill
You say
In talk.mp4 show the ratio of reading time to meeting time as "1 : 4".
It said back
I've added the "1 : 4" strip to talk.mp4 and rendered it as talk-graphics.mp4 in the same folder. It's 1920x1080, 24.3 s, 30 fps.
Check this: the speaker never says this ratio or the words "reading time", so "1 : 4" and the "Reading" label come from you. Check they match what she's describing, or tell me what to change.
