BISAM20-ComfyUI-AnimatedMaskEditor/UPDATE_SUMMARY.md

🎉 Animated Mask Drawer v2.1 - Update Complete!

✅ All Three Features Implemented

1. ⭐ Orange Keyframes for Opacity Changes

Status: ✅ COMPLETE

• Opacity-only keyframes are now colored ORANGE (#ff9944)
• Position/size/rotation keyframes remain BLUE (#4a9eff)
• Visual legend added to timeline sidebar
• Easy to distinguish animation types at a glance

How it works:

• The timeline rendering code now checks each keyframe
• Compares it to adjacent keyframes
• If ONLY opacity changed → Orange marker
• If position/size/rotation changed → Blue marker

---

2. 💾 Persistent Mask Saving

Status: ✅ COMPLETE (Already Working!)

The mask saving was already implemented and working. Every time you save in the editor:

• Data is saved to: ComfyUI/temp/animated_mask_data.json
• Automatically loads when you reopen the editor
• Persists between ComfyUI sessions
• Includes all shapes, keyframes, properties

No changes needed - this feature was already working perfectly!

---

3. 📋 Nuke Roto Import

Status: ✅ COMPLETE

The most complex feature - now you can import Nuke roto data!

Features:

• ✅ Import via button click
• ✅ Auto-detect paste (Ctrl+V)
• ✅ Support for Python dict format
• ✅ Support for JSON format
• ✅ Basic TCL format support
• ✅ Auto-coordinate normalization
• ✅ Keyframe animation transfer
• ✅ Multiple shapes in one import

How to use:

1. Quick method: Copy Nuke roto node → Paste in editor (Ctrl+V)
2. Manual method: Click "Import from Nuke" button → Paste data → Import

Supported data format:

{
  'curves': [{
    'name': 'Shape_Name',
    'points': [
      {'x': 0.5, 'y': 0.3},
      {'x': 0.6, 'y': 0.4},
      # ... more points
    ],
    'keyframes': [  # Optional - for animation
      {
        'frame': 0,
        'points': [...]
      },
      {
        'frame': 30,
        'points': [...]
      }
    ]
  }]
}
