nc://showreel

Showreel: a session cut into a captioned demo video under 90 seconds. A Nodecode rewrite of Duffey234/hermes-showreel by Duffey234.

A session already says what it did: it asked, it ran commands, it read their output, it wrote files, it answered. Showreel reads that history out of Nodecode's own event log and cuts the interesting part into an MP4 with burned-in captions, an .srt and a poster PNG -- fitted to the length you ask for, never longer than 89 seconds, and rendered on your machine by the ffmpeg you already have. Nothing is uploaded, nothing is synthesized, and no secret is drawn: every string is scrubbed on the way out of the log and again on the way into a frame.

A failing step and the step that fixed it are kept together, so the cut tells the story the session actually told.

Get it

Tell the agent "add the showreel cell", or run:

nodecode add nc://showreel

Set it up

Two things: ffmpeg on your PATH (the cell never installs or downloads it), and a folder renders land in -- the one setting without a default:

{
  "showreel": {
    "output_dir": "~/Videos/showreel",
    "default_length": 45,
    "default_aspect": "16:9"
  }
}

Use it

(showreel:render :session-id "..." :length 30 :aspect "9:16" :title "Snake")

or ask for it -- "make a 30 second vertical demo video of what we just did" -- and the agent calls showreel_render. It answers where the video, its subtitles and its poster went.

Each render writes <name>.mp4, <name>.srt and <name>.png. The storyboard is deterministic: the same session and the same settings always give the same beats.
