How to read this channel

Last Sumerian is a 26,300-subscriber channel (about 141 months old) working mainly in Sci-Fi / Time Travel, publishing first in Portuguese. The radar tracks 3 of its uploads. Its strongest signal (breakout score 1.4× the dataset median) reaches 15.7× the channel's subscriber count and has averaged 8,991 views a day since it was published 46 days ago, on “PLANET 9 | AI Sci-Fi Short Series — Episode 1” (413,608 views). That is a lifetime average, not a current rate — one capture per video means this dataset cannot distinguish a video that is still climbing from one that already peaked.

There is one statistic this page deliberately does not print: a per-channel “share of uploads that reached 3×”. Every video on this site cleared that floor before it could be tracked at all, so the figure would read 100% for every channel and would distinguish nothing. What is left instead: 3 tracked uploads pulling 780,627 views between them, the strongest reaching 15.7× its audience. Repeated strong reach across several uploads is the part that suggests a format; one outlier is not. The hook patterns the tracker infers from its titles are statement / cold open (3), and the production choices that repeat are no-face format (no host on camera), ai-generated visuals declared in the title, episodic series / numbered parts, non-english market spoken first, global subs second.

What to copy and what to skip: copy the packaging pattern (title structure, the promise made in the first seconds, the episode length that keeps working) and skip the parts that only this channel can do — an existing subscriber base, cross-posting, or a back catalogue that feeds recommendations. Then compare this channel against the others on its category board: same niche, different market, different length. That comparison is where the transferable part usually hides.

Reproducible playbook

Opening hook (title-derived)

Statement / cold open · estimated hook window 10s before the main body.

Beat rhythm (Cold open → setup → act 2 → climax → resolution)

  • Hook 0%–10%
  • Escalation 10%–55%
  • Turn 55%–85%
  • Payoff 85%–100%

Production choices that repeat

  • No-face format (no host on camera)
  • AI-generated visuals declared in the title
  • Episodic series / numbered parts
  • Non-English market spoken first, global subs second

Derived from the title, duration and market — no frame-level video analysis, and no use of the labels this site writes on an entry.
