Hail Mary highlight trails (Custom Shader)

Starting footage: Dynamic, high-speed night car chase generated with Wan 3.0, featuring high-contrast police sirens, reflections, and drift maneuvers.

Agent direction: Instructed the invideo timeline agent to construct a custom "Prismatic Chroma-Warp" shader directly on the video clip. Directed the agent to isolate high-luminance specular points, stretch them into directional anamorphic motion trails following the vehicle's movement, and expose granular parameter sliders in the inspector.

Manual refinement: Tuned the highlight threshold to eliminate background noise and isolate only the sirens and taillights. Increased trail length for intense drift trails, adjusted chromatic split intensity for spectral edge dispersion, and leveled the audio and final voiceover sequence.
