What problem does it solve?
When assembling multi-scene HyperFrames videos, transitions like crossfades and zoom-throughs can briefly drop the combined opacity of overlapping scene wrappers below 1, causing a glaring white flash at every seam on dark films. This Skill provides the render-correctness doctrine that makes scene-to-scene transitions composite correctly on the master timeline.
Core Features & Use Cases
- White-Flash Guard: Explains the opaque stage-ground prerequisite — painting
#root with an opaque background so opacity dips never reveal the renderer's default white page.
- Injector Mechanics: Documents how the transition injector extends wrapper durations, overlaps scenes, ping-pongs track indexes, and stamps GSAP templates onto the master timeline.
- Template Placeholders: Defines the substitution tokens (
__OLD__, __NEW__, __T__, __DUR__, __DX__, __DY__) used in transition GSAP templates.
- Use Case: While assembling a launch video's index.html, you notice a white flash at a crossfade seam on a dark film; load this Skill to verify the stage-ground background and confirm the injector's overlap and track-assignment behavior.
Quick Start
Use the seam-craft skill to diagnose why a white flash appears at the crossfade seam in my assembled HyperFrames index.html.
