Wan 2.7 is an upgraded version of the Wan video model, and this site lets you use it online. You can generate videos from text or images at 1080p with synced audio and clips up to around fifteen seconds.
New controls include setting the first and last frame, building a video from a nine-image grid, using a subject and voice reference, editing through written instructions and remaking existing videos. It suits people who want more direction over the final shot.
