Encode Mode
Drop list to select the encoding mode to use:
CBR (Constant Bit Rate)
VBR (Variable Bit Rate)
The CBR settings instructs the device to encode
the video using a constant bit rate, thus
ensuring consistent quality and predictable file
size of the recorded video. When using VBR, the
device will vary the bit rate according to the
level of detail in the video at each given point
in time, thus attempting to optimise quality
against file size.
However, for critical video (where detail must
not be lost), and which also has a lot of fast
movement, CBR is the better choice, as VBR
would tend to introduce motion artifacts
(jaggedness and blurriness) into the encoded
video as the encoder attempts to keep up with
