Cliffhanger Engineering for Serialised Verticals
Cliffhangers aren't a writing flourish in a 60-second vertical, they're the mechanism that gets episode two watched. The cut has to land early, not late.

A rendered clip is several hundred frames deep. extract_video_frames pulls one you already paid for; analyze_video helps you find which one first.
Every video model caps clip length. The technique that holds a look across a longer scene isn't a longer prompt — it's defining frames and chaining the joins.
Spotify Canvas is 3-8 seconds, vertical, and loops on repeat. A clip generated to loop beats one trimmed from footage that was never built to.
Near a supplied keyframe, models drift toward their own priors instead of the prompt — and escalating the prompt with more restrictions reliably makes it worse.
Side-by-side benchmarks, pricing, and prompt-by-prompt verdicts on the three frontier AI video models defining 2026 — Sora 2, Google VEO 3.1, and Kling 3.
