Veo 3.1 — Same 10-second story scene, three tiers

"One quiet night, little Fenn set off to find a friend…" · 720p · two beats (6s + 4s, frame-seeded) · native audio & narration

Lite $0.05/s · this clip $0.50

veo-3.1-lite-generate-preview — cheapest tier, 720p only, no extend feature.

Fast $0.10/s · this clip $1.00

veo-3.1-fast-generate-preview — recommended default; best quality-per-dollar, supports 1080p (8s clips) and extend.

Standard $0.40/s · this clip $4.00

veo-3.1-generate-preview — flagship quality, supports 1080p/4K (8s clips) and extend.

Identical prompt on all three tiers. Beat 2 was seeded with beat 1's final frame for continuity, then stitched with ffmpeg — expect a visual/audio seam at the 6-second mark on every tier; production would use Veo's native extend (Fast/Standard) instead. Total test spend: $5.50 of $10 prepay.
