• Following a subject that MOVES across the shot
• Gotchas

Full Production Studio note: this skill drives the toolkit in agamm/video-agent. Clone that repo and run your agent inside it for the scripts/paths below to work; the guidance itself is usable anywhere. reframe converts to a target aspect ratio two ways. Pick by what the footage is: | Footage | Mode | Why | |---|---|---| | Talking head, single subject | --mode crop (default) | Full-bleed vertical; subject fills frame | | Screencast, gameplay, slides, anything where edges matter | --mode pad | Keeps the whole frame; blurred-fill background | --width sets the final output width (height follows the aspect); omit to keep native resolution. For 9:16 social, --width 1080 → 1080×1920, the standard upload size. Crop defaults to center (--focus 0.5). If the speaker sits left/right of center, the default crop clips them. There's no face tracking (by design). Set the crop bias by hand: 1. Read where the subject is: uv run video-agent position-grid in.mp4 --at --spacing 200 -o grid.png, open it, note the subject's center x. 2. focus = subjectcenterx / framewidth (0 = hug left edge, 1 = hug right edge). 3. uv run video-agent reframe in.mp4 -o reel.mp4 --aspect 9:16 --focus 0.62 4.
