One hour of video in. Six Shorts out.

We ran our clip pipeline on a public-domain NASA news conference: the Artemis II crew's post-flight briefing, 59 minutes long. Below are the six vertical, captioned clips it produced, and a log of every step.

The clips

Fire alarm, 80,000 miles from home

Hook: a smoke alarm on the way home, and the rule of "no fast hands."

Hook 5 · Complete 5 · Peak 5 · Standalone 5

What re-entry actually feels like

Hook: like diving off a skyscraper backwards.

Hook 4 · Complete 5 · Peak 5 · Standalone 5

The moment it hit him

Hook: asking for the ship's chaplain, and what he saw behind the Moon.

Hook 4 · Complete 5 · Peak 5 · Standalone 4

Back on Earth, still floating

Hook: 328 days in space never did this to her. Ten days did.

Hook 4 · Complete 5 · Peak 4 · Standalone 5

Launch as friends, land as friends

Hook: the astronaut creed, and how this crew came home.

The run log

01TranscribeWhisper (small.en, int8) with word-level timestamps and voice-activity filtering. 1,520 segments.16 min 31 s
02Score momentsAn LLM agent read the transcript and scored candidates against a written rubric: hook in the first seconds, a complete thought, an emotional or informational peak, and no need for earlier context. Six picks, with scores shown under each clip.Not timed
03Cut, reframe, caption, levelffmpeg cuts each clip, places the 16:9 frame on a blurred 9:16 background, burns in word-timed captions and a title, and normalizes loudness for mobile.2 min 7 s
04Human approvalA person reviews the batch before anything is published. In this demo, that's us.One review

Timings are from a 2-core cloud machine with no GPU. A modest workstation GPU cuts transcription time substantially. Step 2 wasn't instrumented, so we don't claim a number for it.

What this demo doesn't do yet

  • Speaker tracking. Clips use a full frame on a blurred background instead of following the speaker's face.
  • Posting. In production, approved clips go to a scheduler with per-platform copy. Here they stop at approval.
  • Monitoring. Production pipelines add an agent that confirms every run produced its output. A demo run doesn't need one.
