Why Runway Gen-4 Stands Out
Broadcast-Ready Realism
Advanced temporal consistency produces smooth motion, realistic physics, and sharp detail — clips look closer to hand-shot footage than typical AI output.
Five Aspect Ratios
16:9, 9:16, 1:1, 4:3, and 3:4 cover landscape, portrait, square, and classic formats — perfect for YouTube, TikTok, Instagram, and broadcast.
Competitive Gem Pricing
720p at 40 gems (5 s) or 80 gems (10 s), 1080p at 80 gems (5 s) — giving you affordable access to studio-quality video generation.
