where:
description: the description of the video object.
source: the ORDSource where the video data is to be found.
format: the format in which the video data is stored.
mimeType: the MIME type information.
comments: the metadata information of the video object.
width: the width of each frame of the video data.
height: the height of each frame of the video data.
frameResolution: the frame resolution of the video data.
frameRate: the frame rate of the video data.
videoDuration: the total duration of the video data stored.
numberOfFrames: the number of frames in the video data.
compressionType: the compression type of the video data.
numberOfColors: the number of colors in the video data.
bitRate: the bit rate of the video data.
