Good
- Most prompt wins (5/11) and the highest visual quality (7.8)
- Best for people: café close-up, dialogue and concert crowd
- Polished studio lighting on the vertical product spin
Not so good
- Most expensive: $0.15/s with audio ($0.60 a clip)
- Physics misses: the dog never catches the frisbee, and the milk turned into blobs
- Failed once on the wok prompt (not billed; the retry worked)
Best for: People-focused content, talking-head b-roll and product ads where polish matters more than price. Try Google Veo ↗
