+# Sermon Converter
+
+A Rust-based service that automatically monitors a directory for new sermon video files and converts them to an optimized format for streaming.
+
+## Features
+
+- Automatic detection of new MP4 files in the watch directory
+- Efficient video conversion using FFmpeg
+- Preserves audio quality while optimizing video for streaming
+- Automatic file organization with date-based naming
+- Syncthing-aware (ignores temporary sync files)
+
+## Prerequisites
+
+- Rust (latest stable version)
+- FFmpeg installed and available in PATH
+- Sufficient disk space for video processing
+
+## Installation
+
+1. Clone the repository:
+```bash
+git clone <your-repository-url>
+cd sermon-converter
+```
+
+2. Build the project:
+```bash
+cargo build --release
+```
+
+## Configuration
+
+The service uses environment variables for configuration:
+
+- `SERMON_WATCH_PATH`: Directory to monitor for new sermon videos
+- `SERMON_OUTPUT_PATH`: Directory where converted videos will be saved
+
+Example:
+```bash
+export SERMON_WATCH_PATH="/path/to/watch/directory"
+export SERMON_OUTPUT_PATH="/path/to/output/directory"
+```
+
+## Usage
+
+Run the service:
+```bash
+cargo run --release
+```
+
+Or run the built binary:
+```bash
+./target/release/sermon_converter
+```
+
+The service will:
+1. Process any existing MP4 files in the watch directory
+2. Continue monitoring for new files
+3. Automatically convert new MP4 files as they appear
+
+## Running as a System Service
+
+To run as a systemd service, create a service file at `/etc/systemd/system/sermon-converter.service`:
+
+```ini
+[Unit]
+Description=Sermon Video Converter Service
+After=network.target
+
+[Service]
+Type=simple
+User=<your-username>
+Environment="SERMON_WATCH_PATH=/path/to/watch/directory"
+Environment="SERMON_OUTPUT_PATH=/path/to/output/directory"
+ExecStart=/path/to/sermon_converter
+Restart=always
+RestartSec=10
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Enable and start the service:
+```bash
+sudo systemctl enable sermon-converter
+sudo systemctl start sermon-converter
+```
+
+## Video Conversion Details
+
+The service converts videos using the following FFmpeg settings:
+- Video codec: H.264 (libx264)
+- Audio codec: AAC
+- Video preset: medium
+- Constant Rate Factor (CRF): 23
+- Pixel format: yuv420p
+- Audio bitrate: 128k
+- Audio sample rate: 44100 Hz
+
+## File Naming Convention
+
+Converted files are named based on the original filename's date pattern:
+- Input: `YYYY-MM-DD_sermon.mp4`
+- Output: `YYYY-MM-DD_sermon_converted.mp4`
+
+## Troubleshooting
+
+- **FFmpeg not found**: Ensure FFmpeg is installed and in your system PATH
+- **Permission denied**: Check that the service has read/write permissions for both watch and output directories
+- **Files not detected**: Verify the watch directory path and that files are complete before processing
+
+## License
+
+See LICENSE file for details.
+
+## Contributing
+
+Contributions are welcome! Please submit pull requests or issues through the repository.
