ClipTidy

ClipTidy is a Unity editor utility that removes redundant keyframes from Animation Clips while preserving the visual output and clip duration. Perfect for cleaning up complex animations with dozens of properties where unnecessary keyframes accumulate during iteration.

Features

• Smart Redundancy Detection - Identifies truly redundant keyframes based on values and tangent modes
• Clip Duration Preservation - Never shortens animation clips unintentionally
• Batch Processing - Multi-select and process multiple clips at once
• Simulate Mode - Preview what would be removed before committing changes
• Detailed Reporting - See exactly which keyframes were removed from each property
• Object Reference Support - Handles material curves and other object references
• Undo Support - Full Unity undo/redo integration
• Debug Logging - Toggle verbose logging with keyframe timestamps

Basic Workflow

1. Select Animation Clips in your Project window
2. Right-click and choose one of:
   • ClipTidy → Tidy Selected Clips - Clean clips immediately
   • ClipTidy → Tidy Selected Clips (Simulate) - Preview changes without actually cleaning
3. Review the Console for a summary of removed keyframes

Alternatively, you can use Assets → ClipTidy → Tidy Selected Clips from the top toolbar menu
