Re-render a previously generated sprite animation from a new view: the same motion and timing, seen from a different angle (e.g. a front-facing walk cycle turned into the same walk seen from the back). Pass the spritesheet_url you received from animateSprite, animateSpriteKeyframes, transferMotion, editSpritesheet or an earlier call - it must be a spritesheet you generated within the last 7 days; arbitrary external images are not accepted - and, as image (URL or base64), the character exactly as it must appear in the new view: it becomes the first frame of the animation. To produce that image, call rotateSprite on the animation's first frame (or any image of the character) and pick the view you want. An optional final_image fixes the last frame (it defaults to the first frame, for cyclic or returning animations), and an optional prompt steers the result: the character's facing in the new view ("its back to the camera"), where the action goes ("the kick goes to the left of the frame"), or anything else about the motion. Runs on hydra (default) or hydra-plus (finer detail). The job result is the same sprite result as animateSprite (spritesheet_url, video_url, grid fields, optional GIF and frame URLs). The animation covers the source's own length (up to 5 seconds; a longer source is sped up to fit), so omit duration unless you need to change that. Credits are held for that length when the job is accepted, or for 3 seconds when it is shorter (a new view is a new generation, and hydra generates at least 3 seconds); the final charge is the model's rate × seconds of video generated, never more than was held, and the difference (or everything, if the job fails or is cancelled) is refunded. Pass an optional request_id to tag the result for later retrieval via listGenerations (type spritesheet). Async generation job: returns {id, status} - poll getApiJob (job and credit contract: see the server instructions).

Credits: Cost varies by model and duration (credits/second × duration).
