MPEG-2: Simple, Main and High.
H264: Constrained Baseline, Main and High.
Video Bitrate
Sets output bit-rate in CBR mode.
HD Encoder: 250kpbs – 38Mbps
SD Encoder and Transcoder: 250kbps – 19Mbps
Rate Control Mode
Video CBR (Constant Bit Rate) or CVBR (Capped Variable Bit
Rate).
VBR Max
Sets the bounds of the output bit-rate when the encoder operates in
CVBR.
Capped VBR
When in CVBR mode, this sets the target Quantization
Parameter of the encoder. High QP will result in more
compression at the expense of quality. Low QP will result in
higher bit-rate and better quality.
Target QP.
The encoder will use the selected QP unless the resulting bit-
rate is outside the upper bound set by VBR Max.
Reduced Delay Mode
Enabling this mode reduces the encoding delay.
Please note that enabling this feature will lead to less processing
and therefore could impact picture quality at lower bitrates.
WSS Blanking
Enables WSS Blanking on the encoded output (Encoder only)
Picture In Picture
Enable PIP video. This will generate a new selectable service for
use on any of the output modules. Both share the same audio.
PIP Resolution
Sets the resolution of the PIP video.
• 416x240
• 352x288
• 352x240
• 192x192
• 128x128
• 128x96
PIP Video Bitrate
Sets the bit-rate of the PIP video. Range: 250kbps to 1Mbps
The CBR video bit-rate affects only the video PID. An IP output may still be a
VBR transport stream. Some IP receivers require that the IP output is set to CBR
mode. This can be set on the Port Settings tab of the output stream
Transcoder PIP is from the default PID values as the Main service whereas
Encoder PIP PID value is configured on the service page.
