• Seedance 2.0 is a multi‑modal AI video generator that transforms images, text, audio, and reference videos into cinematic HD clips, offering character consistency, motion control, and built‑in audio.
• Select up to 12 files across images, videos, audio, or text; drag them into the upload area or click the button, ensuring clear faces for best character consistency.
• Enter a natural‑language prompt describing the desired scene, referencing uploaded assets; the AI interprets intent and maps it to cinematic style, camera motion, and audio cues.
• Click Generate; the platform processes inputs, applies motion replication from reference clips, maintains character consistency, and auto‑generates synchronized sound effects and music.
• Review the preview panel; use built‑in quality analytics to assess resolution, frame consistency, and audio sync before final download, and adjust settings if needed.
• Download the HD video in the chosen aspect ratio; the file is watermark‑free and ready for social media or professional use.
• Analyze the output for character fidelity, motion accuracy, and audio alignment; use these metrics to refine prompts or asset selection for improved cinematic quality.
• For developers, use the API endpoint to submit assets and prompts programmatically, enabling batch generation and workflow automation, and integrate into existing pipelines.
