VBR
VBR stands for Variable Bit Rate, the recording
format for automatically controlling the bit rate
(the volume of recording data in a given time
segment) according to the scene being recorded.
For fast-moving video, a lot of hard disk space is
used to produce a clear image, so the recording
time to the media shortens.
