Metadata is an extra information which describes the file. 

For video files, most common parameters are video's resolution, its duration and key-frame information. 

Metadata also includes time and date of footage, time and date of file creation, frame rate, bitrate and other specific video parameters.

Movavi Video Converter software does not allow to edit metadata directly. 

Most of the metadata is filled in automatically, depending on resulting video's parameters.

Such parameters as time and date of file creation are also carried out automatically by the system once it is created.
