Preserve physics through the impact cut | Academy

The first strike asks two shots to feel like one suspended instant. The cut works only if the bodies, blades, and almost-contact distance survive the transition. Treat that frozen pose as a continuity asset of its own.

Exact source brief

Write a prompt for next sequence. First contact. Two shots, one frame-perfect match cut: side-profile duel as the lead charger closes—freeze just before the weapons touch—then cut to a slow-motion 180-degree orbit around that frozen moment, and ramp back to real time as the odachi shatters on the crystal blade. Keep a staggered line of chargers behind the lead, with exact gaps.

This is the exact request shown being handed off for expansion by Claude or the source skill. It records the directorial intent, but it is not presented as the complete generator prompt.

Lock the instant before contact

Shot one ends in side profile as the lead charger closes. The weapons stop just before touching. Shot two begins from the same body and blade positions, then orbits 180 degrees around the held moment in slow motion. Real time returns only as the steel blade breaks against crystal.

That sequence has three linked locks:

Lock	What must remain true
Pose	The last frame of shot one and first frame of shot two show the same bodies and weapon angles
Time	The orbit holds the near-contact instant; acceleration returns at the shatter
Material	A vertical steel attack meets a diagonal crystal parry, and steel is the material that breaks

First bullet-time impact generation with the intended duel movement but an imperfect finish

The source judges the movement as working. The match-cut idea, orbit, and impact direction are present, so rewriting their structure would discard valid instructions.

Diagnose at the level that failed

The shot is demanding because it combines two moving bodies, time dilation, an orbit, and a material interaction. Complexity alone is not a reason to rewrite. Inspect the generated result in the same order as the locks.

First compare the end pose and start pose. Then follow the gap between the blades during the orbit. Finally check the exact instant time accelerates and which material fractures. If those relationships hold but the image lacks polish, keep the prompt and generate another result. If the pose resets, the orbit abandons the contact point, or crystal breaks instead of steel, the corresponding lock needs revision.

“Almost right” is not one diagnosis. Name whether the defect belongs to pose continuity, temporal continuity, material behavior, or image quality before deciding to rewrite or reroll.

The proof is a seamless mental handoff: you should be able to pause on the last pre-cut frame, switch shots, and still account for every body, blade, and force.
