Slow motion and speed ramps
Design slow motion inside the shot; write everything else as real time, because Seedance drifts toward slow motion.

Slow motion and ramps [official guidance]:
Slow motion is captured fast and shown at 24 fps, with the camera move written in screen time.
Everything else says real time, no ramps. A key action move excludes slow motion by name.
The two never share a shot. OUTPUT SETTINGS pins the mode per segment.
A ramp in the take [best available, not yet validated]: lock the base take first, then one sentence at a named beat, with a cut-list ramp as fallback. Never inside lip-synced speech. Slowing generated footage far below real time in the edit is likely to judder.
Food and impacts: only the moment of impact goes slow, as its own shot.
