6 sec or 90 sec? Decision Tree.
The Hook Window Myth
Many marketers think shorter is always better. Wrong. The hook window is 1.2 sec (TikTok) to 1.5 sec (Meta), regardless of total length. What happens after the hook depends on the product. High-ticket needs 60 to 90 sec for trust building. Impulse products are fine with 6 to 12 sec.

ROAS with Wrong Format Match
Decision Tree
Long-Form or Short-Form
- Long-form (60–90s): when AOV >120 EUR, considered purchase, education needed
- Long-form: when heritage or founder story is part of the sell
- Short-form (6–15s): when AOV <40 EUR, impulse buy, clear visual hook
- Short-form: when in the awareness phase (cold audience) and pure pattern interrupt
- Mid-form (20–40s): when AOV 40–120 EUR, often the sweet spot for DTC
Example
A bike brand with AOV 1,890 EUR stopped short-form (12s) entirely and ran only long-form (60s). ROAS climbed from 2.1x to 3.4x. High-ticket needs time to build trust.
Watch-Time Ratio as the KPI
Instead of chasing cut length, optimize for watch-time ratio. For a 90-sec cut, 30 to 40 sec should be watched on average. For a 12-sec cut, 8 to 10 sec. When the ratio breaks, the format was the wrong choice.
