What it does

Once installed, the agent can help you turn gameplay of a game mod into a short promotional video. It guides you to script a repeatable take, record only the game window and the game's own audio, pick good moments from timestamped contact sheets, and assemble the result from a JSON edit list with titles, transitions, music, a watermark and a fade-out. It also gives style advice, such as keeping titles short and crediting other creators when you compile their clips.

Great for

  • Mod authors who want a 30-second demo or trailer for a game mod
  • Creators assembling a montage or compilation from clips they have permission to use
  • Developers already using the um command-line toolchain on Windows with ffmpeg

Skip it if

  • Users without a Windows gaming setup, since the recording relies on Windows window capture and WASAPI process loopback
  • Re-uploading or editing other people's clips without permission, because the skill advises crediting and asking permission for promotional use but does not enforce it
  • Anyone expecting a standalone editor; it depends on the external um tool, ffmpeg and Pillow being installed

Try asking

  • “Record a 40-second take of my Terraria mod and cut a 30-second showcase video for X”
  • “Make a contact sheet of this clip so we can pick the best explosion moments”
  • “Build an EDL JSON that adds one-line titles, a fade transition and background music to these three clips”
  • “Combine these creators' clips into a montage with on-screen credits for each handle”

Get better results

  • Script the action in the game first so you can reshoot the same take after a fix, and restore a clean world backup before each take
  • Use um video contact to read the timestamps and choose in and out points before writing the EDL, then check a contact sheet of the finished video
  • Keep clip audio around 0.5 to 0.8 volume and credit every creator on screen and in the post text when compiling others' clips
