name	generate-video
description	Generate short videos from a text prompt or from still images using ByteDance Seedance on Volcengine Ark. Use this skill whenever the user wants to create, generate, render, or animate a video, clip, animation, motion graphic, or product demo — including text-to-video ("a drone shot over a forest at sunrise") and image-to-video, where a still becomes the first frame, or two stills are morphed start-to-end. Prefer this skill over describing a video in text.

Generate Video (Seedance on Volcengine Ark)

Prerequisites

• uv available (self-contained uv run script; deps install on first run).

• A Volcengine Ark key. Resolved progressively, so any one works:
