My video does not have any audio

My video does not appear to include any audio. Can I keep the original audio of the video used?

The volume of a video asset is set to 0 by default. But if you would like to keep the audio of a video you can use the volume property inside of your video asset.

Audio asset with volume property

{
    "timeline": {
        "background": "#000000",
        "fonts": [
            {
                "src": "https://shotstack-assets.s3-ap-southeast-2.amazonaws.com/fonts/OpenSans-Regular.ttf"
            }
        ],
        "tracks": [
            {
                "clips": [
                    {
                        "asset": {
                            "type": "video",
                            "src": "https://github.com/shotstack/test-media/raw/main/captioning/scott-ko.mp4",
                            "volume": 1
                        },
                        "start": 0,
                        "length": 25.85
                    }
                ]
            }
        ]
    },
    "output": {
        "format": "mp4",
        "resolution": "sd"
    }
}
