The 10 minute video recorded by Xiaomi camera belongs to semi-structured data. Semi-structured data is a data type between structured data and unstructured data. It contains some structured information, but it doesn't strictly follow a specific data pattern and format like structured data. In video data, there are some metadata information, such as video length, resolution and coding method, which can be regarded as structured data. The content of the video itself is unstructured and cannot be directly processed and analyzed. Therefore, video data is usually regarded as semi-structured data.
