First & Last Frame
Seedance 2.5 is ByteDance’s flagship video model, combining two capabilities that rarely coexist: up to 30 seconds of continuous generation and frame-accurate endpoint control. It also accepts image, video, and audio references — the most flexible input set in the lineup.
The 480p/720p output tiers trade absolute resolution for duration and control — a sensible exchange for social content, previz, and story-driven clips where length and choreography matter more than 1080p pixel counts.

A busy Tokyo crossing at night: crowds flow, neon signs flicker, rain begins falling — synchronized ambient audio of footsteps, chatter, and the first raindrops.

Long Travel Shot
Continuous 25-second drone flight: start low over a lavender field, rise to reveal rolling Provence hills, a stone village, and the setting sun — documentary cinematography.
