## Description

Record and cut a short showcase video of a game mod, or a compilation of clips, ready to post on X/YouTube. Records the game window with only the game's own audio, picks moments from contact sheets, and edits with one-line animated titles, creator credits, transitions, music, watermark and fade-out via an EDL JSON. Use when the user wants a demo video, trailer, clip or montage of a mod, or wants to combine existing clips into a styled video.

# Showcase video

A mod isn't finished until you can show it in 30 seconds. The toolchain is `um win record` (capture),
`um video contact` (look), `um video compile` (edit), all ffmpeg + Pillow.

## 1. Make the take repeatable
- **Script the action.** Use a mod-side timeline or command sequence (spawn enemies, fire the weapon, cue
  the boss), a scenario with triggers and camera moves, or a WinDrive command list. The first clean take
  should be reproducible exactly, so you can reshoot after a fix.
- **Restore the world before each take.** Explosions crater worlds; units die. Keep a pristine copy with
  `um backup` and restore it every take.
- **Clean frame.** Hide debug text, fix the camera zoom (the Terraria showcase used 1.5x so 1080p frames
  read like a 720p cut), run at full speed when unfocused, and hide the cursor (capture uses
  `capture_cursor=0`).
