MotionEyes Visual Analysis

Overview

Analyze UI motion by comparing frames directly. This skill produces annotated images plus a JSON summary of motion signals (translation, scale, rotation, opacity, color) and changed regions. It complements MotionEyes traces when instrumentation is unavailable or insufficient.

Use With the Other MotionEyes Skill

• Use motioneyes-animation-debug when you can instrument the app and need precise timing or value traces.
• Use this skill when you only have pixels or when .transition and similar effects do not surface in MotionEyes logs.

Inputs

Use one of these inputs:

• Frames directory with sequential image files (PNG/JPG).
• Video file captured from the simulator (preferred). Frames are extracted at --fps.
• macOS window capture using screencapture with a window id.
