        size: .fit(.hd), // size to fit or fill
        // quality, fps, alpha channel, profile, color primary, atd.
        edit: [
            .cut(from: 2.5, to: 15.0), // cut, in seconds
            .rotate(.clockwise), // rotate
            // crop, flip, mirror, atd.

            // modify video frames as images or access pixel buffers
            .process(.image { image, _, _ in
                image.applyingGaussianBlur(sigma: 7)
            })
        ]
    ),
    optimizeForNetworkUse: true,
    // Audio
    skipAudio: false,
    audioSettings: .init(
        codec: .opus,
        bitrate: .value(96_000)
        // quality, sample rate, volume, atd.
    ),
    // Metadata
    skipSourceMetadata: false,
    customMetadata: [],
    copyExtendedFileMetadata: true,
    // File options
    overwrite: false,
    deleteSourceFile: false,
    // State notifier
    callback: { state in
        switch state {
        case .started:
            print("Started")
        case .completed(let info):
            print("Done: \(info.url.path)")
        case .failed(let error):
            print("Error: \(error.localizedDescription)")
        case .cancelled:
            print("Cancelled")
        }
})

// Observe progress
task.progress.observe(\.fractionCompleted) { progress, _ in
    print("Progress", progress.fractionCompleted)
}

// Cancel compression
task.cancel()
