About this skill

Problem

When a video draft needs to move quickly, a full Seedance 2.0 generation pass can take longer than a review cycle allows. seedance 2.0 fast is a thin client for dLazy's hosted API that targets the fast variant of ByteDance's Seedance 2.0. It is useful for text-to-video, multi-modal references, and first/last-frame prompts where the goal is a fast, iterable output rather than the final render.

How It Works And Boundaries

  • Inputs: supports prompt, image/video/audio references, and first/last-frame controls. Local file paths are uploaded to dLazy media storage so the cloud model can read them.
  • Execution: requests are sent to dLazy's inference endpoint, and generated URLs are hosted by dLazy. With --no-wait, the response includes a task ID that must be polled separately.
  • Auth And Errors: requires a dLazy API key. Common failures include missing credentials, missing required parameters, local file read errors, insufficient balance, and backend task failures.
  • Boundaries: best for fast preview and composition/motion/style checks; it is not local inference and not a substitute for higher-quality full generation or local asset processing.

Use Cases

  • Before a video review, generate candidate shots from a text prompt and reference images quickly.
  • Constraint a first and last frame into a short transition video for storyboard rehearsal.
  • When prototyping ads, use multimodal assets to quickly validate motion and visual style.
  • During cloud API calls, poll generated video results using the async task ID.

Best For

  • Video director assistants who need quick multiple shot drafts to compare motion.
  • Ad creative operators who must validate short-video selling points before launch.
  • Application engineers who integrate dLazy cloud video generation and async task handling.
  • Storyboard designers who need first/last-frame constraints into previewable transitions.
