This site offers the Wan 2.7 model for making 1080p video clips up to fifteen seconds long with improved motion. You can set the opening and closing frames, add up to nine reference images and turn a three-by-three grid storyboard into a moving sequence.
There is also a Wan 2.7 image studio that produces 4K pictures with control over faces and colour, plus video editing tools, so you can prepare stills and clips in one place.
