Describe this Element

Name	Format.ImageDataRate
Definition	The element FORMAT.IMAGEDATARATE should be expressed as an amount of data per second. It indicates the amount of data that is played out from a digital video file for every second. Although optimal data rates are often dependent on the codec used to compress and encode a digital file, generally speaking, a larger data rate translates into a better quality playback.
Refinements and Encoding Schemes
	Enter a number followed by the data rate, expressed as the measurement scale per second.
Guidelines for Usage	The measurement scale applied to a data rate is variable depending on the intended purpose of the file (editing, distribution over LAN or Internet, etc.) Enter a number followed by the measurement scale: kilobits/second bytes/second kilobytes/second megabits/second
Obligation to Use	Mandatory
Repeatable Element	Apply multiple times, as needed
Type of Data Entry	Text String
