Impact Dynamics
Physical cause. Physical effect.
“Physics described in cause-and-effect language, not genre labels.”
Impact Dynamics generates per-shot physics consequences when energy thresholds are met or shot roles require physical cause-and-effect. ID operates through three specialized modules: Vehicle Impact (trajectory deviation, suspension compression, dust displacement, ground deformation), Environmental Impact (light bloom timing, debris arc direction, smoke density ramps), and Aftermath (residual smoke drift, wind response, light temperature cooling).
ID writes physics in physical language — "suspension compression on rough terrain" rather than "action scene." "Dust displacement from tires" rather than "dramatic effect." This specificity matters because AI video models respond to physical descriptions with physically grounded motion, while genre labels produce stylistic interpretations that may not match the narrative.
Physics consequences are only activated when the shot's energy level meets the threshold or the shot role demands it (IMPACT_EVENT always activates physics; ENVIRONMENT_ESTABLISH typically does not). This prevents over-specification of calm scenes with unnecessary physics detail.

Director's Notes
AI video models are visual engines — they render what you describe. If you describe "an exciting car chase," you get a generic car chase. If you describe "suspension compression on rough terrain, dust displacement from tires, headlight beams cutting through particulate cloud," you get physically grounded motion that looks like it was filmed on location. ID translates narrative action into the physical language that generation models can faithfully execute.
