16 Product Film

product-film

A Claude Code skill for building and re-cutting short product films — the 60–120 second kind that alternates typographic title cards with screen recordings of a product working, and ends up on a homepage, a launch post, or YouTube.

It exists because that job looks simple and is mostly judgment, and because the judgment only becomes affordable if the film is a **build** rather than an **edit**. A reviewer will give you dozens of rounds of notes, most of them about pace, and will reverse themselves. Everything here follows from designing for that.

Claude picks it up automatically. Invoke explicitly with `/product-film`, though it should trigger on its own for "cut this video down to 90 seconds", "turn this recording into something polished", "this looks blurry", or "add typing sounds to this".

What's in it

SKILL.md                      the craft: architecture, resolution, cut discipline,
                              pacing, sound, build gates
references/
  beat-timeline.md            typographic beats as a deterministic seekable timeline,
                              rendered frame by frame — and the gotchas that cost days
  typing-sfx.md               the full typing-SFX workflow, sample to final mux
scripts/
  frame_motion.py             find rest frames; check that cuts land on them
  cut_map.py                  segment ↔ film timecode, read from the concat list
  contact_sheet.py            tile several moments into one image to look at
  build_typing_bed.py         keystroke bed from a real recording, per a JSON spec
  scan_typeon.sh              locate the frame each type-on starts

The parts worth knowing before you read further

**Cut only on a frame that has come to rest.** Cutting away while the picture is still scrolling reads as disorienting — the eye is still tracking movement when the image is taken away. Measure it rather than eyeballing it,
