ByteDance's Seedance 2.5 image-to-video starts the clip on a still you supply and animates it, with sound in the same pass. Clips run 4 to 30 seconds at 480p, 720p or 1080p, and an optional closing still makes the shot arrive on a set frame.

snow-glass-spin The still already holds the burst at its peak — fragments frozen mid-explosion, one arm raised — so the prompt only sets it moving: the spin, the skirt flaring with the turn, a look thrown back over one shoulder. `duration_seconds` `4`, `aspect_ratio` `adaptive`; `generate_audio` is `true`, unlike most of this family. `resolution` `720p` keeps the flying edges sharp.

frozen-glass-burst The still frame does all the setup for the frozen time: raindrops stopped in mid-air, a shattered glass facade holding its shape as a motionless shockwave. The prompt only has to start it moving — she closes her fist, the shards spiral into orbit, and the whole wave blasts past the lens as the rain falls again. The camera charges in and arcs around her while several million shards each move on their own; this one is here to test the ceiling.

sunken-ballroom The still fixes a whole ballroom underwater with the chandelier still burning and a figure weightless at the centre of it. The prompt takes over the weightlessness itself: the gown unfurls, the gold dust draws a ring, and she opens both arms and rises toward the light. This one is vertical, so set beside the two wide clips it shows what adaptive does — the output follows the aspect ratio of the first frame.

suspended-wave The reverse test: the camera never moves, the spectacle does. The still supplies a wall of water hundreds of metres high, frozen mid-break, with the shoals inside it stopped as well; the prompt only lets the crest start to fall and the droplets rise against gravity. If you want to catch a model sneaking in a push-in, this is the easy one to read — nothing but the water should be moving.
