Meaning
Variable bitrate allows the encoded data rate to change with content complexity or an encoding strategy.
A practical example
A mostly static diagram may require less data than a detailed moving scene within the same export.
What to check
A single average rate cannot describe every instant. Measure the exported file and inspect difficult passages rather than assuming average size guarantees visual quality.
