Duration: 4–6s is cheapest and fastest. 8–10s is the sweet spot. 12s is max (Seedance only). Resolution: Draft at 480p or 720p. Final export at 1080p. Aspect ratio: 9:16 for mobile, 16:9 for web/YouTube, 21:9 for cinematic, 1:1 for cross-platform. Video Remix: Use it to tweak lighting, pacing, or background without regenerating from scratch—saves cost. Audio: Kling and Veo support audio generation (adds cost).
