Seedance Extend A Clip

Extend @Video1 forward by [8] seconds. Continue directly from its last frame with no cut: same characters, same location, same lighting, same color grade and the same camera style.

What happens next: [the dog drops the ball at the owner's feet, then runs off toward the lake].

0-4 seconds: [The dog trots back toward the camera with the ball and drops it at the owner's feet.] The camera keeps the same height and movement as the end of @Video1.
4-8 seconds: [The dog turns and sprints toward the lake; the camera pans to follow and settles on a wide shot of the water.]

Sound: continue the ambient sound of @Video1 seamlessly; add [paws on grass and a splash at the end]. If @Video1 has music, keep it going at the same volume. No new dialogue, no subtitles.
Do not change anyone's appearance or add new people.
