keyframe-data-model

What problem does it solve?

This Skill provides a frame-based keyframe data model and a lightweight state machine to manage crop and highlight animations, ensuring origin-correct edits and deterministic interpolation.

Core Features & Use Cases

• Frame-based keyframes (not time-based) with explicit frame numbers
• Origin tracking (permanent, user, trim) to support persistence and cleanup
• A simple state machine for initialization, editing, and trimming
• Interpolation and validation rules to maintain invariants across keyframes
• Use in Framing and Overlay workflows to drive crop regions and highlight effects

Quick Start

Initialize the keyframe model, add keyframes via actions, and rely on the state machine to enforce invariants during editing.
