Listing walkthrough from 8 photos: seven 4-second Wan 3.0 transitions

A listing walkthrough needs the camera to travel from room to room. Using photo N as the first frame and photo N+1 as the last frame gives a transition clip between each pair: eight photos make seven clips.

Run the 480p draft pass first, drop transitions that morph badly, then rerun only those at 720p. Pairing code:

photos = ["a.jpg", "b.jpg", "c.jpg", "d.jpg",
          "e.jpg", "f.jpg", "g.jpg", "h.jpg"]
pairs = list(zip(photos, photos[1:]))
print(len(pairs), pairs[0])
for first, last in pairs:
    job = {"model": "wan-3.0", "duration": 4, "resolution": "720p",
           "first_frame": first, "last_frame": last}
