Image: re-rendered to 4K by a generative model, so fine detail can shift and text is worth checking after; a GIF comes back as a still. Video: 4K, priced per second, up to 5 minutes at a time. With timeline_id and clip_id only the stretch the clip plays is upscaled and priced, and the result takes the clip's slot when it lands. Returns a job.
