## Usage

### LivePhotoCreator Node

The LivePhotoCreator node takes the following inputs:
- **images**: Image sequence (IMAGE type)
- **key_frame_index**: Index of the frame to use as the static image (default: 0)
- **duration**: Duration of the Live Photo in seconds (1-5 seconds)
- **fps**: Frame rate of the output video (1-60 fps)
- **audio**: Optional audio input

Outputs:
- **photo**: Selected key frame as static image
- **video**: Path to the generated video file
- **output_path**: Path to the output directory

### LivePhotoPreview Node

The LivePhotoPreview node allows you to preview the created Live Photo:
- Input: Takes the video path from LivePhotoCreator
- Output: Interactive preview with hover effect

### ImageCompareTransition Node

The ImageCompareTransition node creates smooth transition effects between two images:
- **Inputs**:
  - **image1**: First input image (IMAGE type)
  - **image2**: Second input image (IMAGE type)
  - **frames**: Number of transition frames (2-120 frames)
  - **fps**: Frame rate of the transition (1-60 fps)
- **Output**:
  - **frames**: Generated transition frame sequence

Features:
- Smooth left-to-right sliding transition effect
- Automatic image size matching
- Compatible with VHS video nodes for further processing
- Customizable frame count and frame rate

## Example Workflows

### Basic Live Photo Creation
1. Load your video using the "Load Video" node
2. Connect the video output to LivePhotoCreator
3. Configure the desired key frame, duration, and FPS
4. Connect LivePhotoPreview to see the result
5. The output files will be saved in the ComfyUI output directory

### Image Transition Workflow
1. Load two images you want to transition between
2. Connect them to ImageCompareTransition node
3. Adjust frames and fps parameters
4. Use VHS nodes to save the transition as video
5. Check the example workflow in [haihyper_example.json](./example/haihyper_example.json)

## Output Format

The node creates two files in the output directory:
- `IMG.JPG`: The static image
- `IMG.MOV`: The video component of the Live Photo

These files are named and formatted to be compatible with iPhone's Live Photo feature.

## Notes

- The video duration must be between 1 and 5 seconds to be compatible with iPhone Live Photos
- The output video is automatically scaled to maintain quality while keeping file size reasonable
- Audio support is optional and will be included if provided
- Preview requires mouse hover to play the video portion

## Requirements

- ComfyUI (latest version)
- Python 3.x
- OpenCV-Python
- Pillow
- FFmpeg

## Troubleshooting

If you encounter any issues:

1. Make sure FFmpeg is properly installed and accessible from command line
2. Check that all required Python packages are installed
3. Verify that the input video is valid and not corrupted
4. Check the ComfyUI console for error messages

## Known Issues

- Preview may not work in some browsers that block autoplay
- Very large videos may take longer to process
