2.2 Detailed Encoder Configuration
Shown below in Figure 7 is the encoder profile configuration form, which lets you set the video and
audio encoding format and bitrates. The QVENC4K encoder will automatically detect and adjust for
the SDI input video resolution and format. The encoder contains a built-in video scalar that
provides the QVENC4K the ability to change the video resolution before it is encoded and output
as a stream.
Figure 7. Encoder Profile Example
The QVENC4K outputs the encoded video stream as a capped Variable Bit Rate (VBR) IP stream.
VBR video encoding is more efficient than Constant Bit Rate (CBR) encoding because it only uses
the amount of bandwidth needed to encode the video content. There is no wasted bandwidth to
carry Null-packets for filler. However, a VBR stream may have large variations in bit rate.
