image-to-cinematic-video

Turn a prompt or an existing image into a polished multi-scene cinematic short video using Seedance for clip generation, uguu.se for file hosting, and FFmpeg for last-frame extraction and crossfade stitching. Supports two modes — PARALLEL (multiple scenes from the same reference image, concurrent, ~3 min total) and CHAIN (each scene starts on the last frame of the previous scene, sequential, ~3 min per scene, produces one continuous long take). Use this skill whenever the user wants to "make a video from an image", "animate this picture", "generate video scenes", "create a cinematic short", "stitch AI videos together", "make a long continuous video", "chain AI clips", or any workflow that goes from one reference image to a multi-clip stitched video. Also trigger when the user mentions Seedance, image-to-video, video stitching, crossfades between clips, frame chaining, last-frame continuity, or wants to turn a generated image into motion. Covers the full pipeline end-to-end — generate image with the chat-level generate_image tool (Gemini Nano Banana Pro by default) → pull the real bytes from /api/images/:id → upload to uguu → Seedance (with the relative-filename quirk handled) → copy output into the project folder → extract last frame → upload → chain into next scene → FFmpeg xfade stitch → upload final → write manifest.
