Seedance 2.0 4K output hits Replicate

While native 4K video generation yields incredible visual quality, the steep computational cost and slower speeds mean it will likely remain a luxury feature reserved for final exports, while 1080p generation with post-upscaling remains the pragmatic developer choice.

• –**True 4K Resolution:** Generates native 10-bit H.265/HEVC video at 3840×2160, offering superior fine-grained details and motion fidelity compared to post-process upscaled outputs.
• –**Complex Multimodal Inputs:** Supports combining text prompts with up to nine reference images (for styling/consistency), three reference videos (for motion transfer), and three audio tracks (for native lip-syncing).
• –**Steep Pricing Premium:** Running native 4K on Replicate carries a high cost (up to $1.25 per output second), compared to standard 720p at $0.22/sec or 1080p at $0.55/sec.
• –**Integrated Audio Generation:** Synthesizes synchronized sound effects, background music, and direct dialogue (triggered using double quotes in prompt text) natively.
