Description:
Set Stream Venc
Specifies Video encoding
H264 ( AVC)
H265 (HEVC)
Channel Name
Specifies the Encoder Web Page Name
Bitrate control
Specifies the Video Encoding control
VBR ‘Variable Bitrate’ Encoder work with same encoding quality
setting, result in a high fluctuating output.
CBR ‘Constant Bitrate’ Encoder change encoding quality settings
output for a more constant output.
.!. ENC-500 do not support a CBR TS with added Padding bits.
Key interval
Specifies the interval of intra frames. Intra frames (= I-Frames) are total
independently coded and are used as references frames.
Encoded size
Specifies the output resolution. Following Resolutions are available
1920 x 1080
1280 x 720
960 x 540
850 x 486
720 x 576
720 x 540
720 x 404
704 x 576
640 x 480
640 x 360
Auto = input resolution on HDMI Main, on HDMI 2
nd
is maximal
1280x 720
Bitrate
Specifies the average Video Bitrate.
.!.
W
ith VBR Mode with changed ‘MinQp’ and ‘MaxQp’ the output
could be complete different.
Fluctuate Level
Specifies the CBR fluctuate Level from Auto over Level 1 to Level 5 while
Level 5 allow most fluctuation.
Only available with ‘’Bitrate control=cbr’
H264 Profile
Profiles specify the syntax (i.e. algorithms) of the video codec, select
between:
Baseline
Main
High

.!.
Teracue recommends High Profile.
Only available with ‘Stream Venc=H264’
Encoding frame rate
Specifies the Output Frame Rate independent from the Input Frame Rate.
MinQp
Specifies the minimum Quality settings, while Q1 is best and Q51 is worst.
e.g. change the ‘MaxQP’ from 30 to 50 reduce the video quality and the
average bitrate.
.!.
Teracue recommends the standard value (5) left unchanged.
Only a
vailable with ‘’Bitrate control=vbr’
MaxQp
Specifies the maximum Quality settings, while Q1 is best and Q51 is worst.
e.g. change the ‘MinQP’ from 5 to 20 reduce the video quality and the
average bitrate.
.!.
Teracue recommends the standard value (30) left unchanged.
.!.
MaxQp must be minimum 1 higher than MinQp
Only a
vailable with ‘’Bitrate control=vbr’
Max Bitrate
Specifies the average Video Bitrate.
.!.
In
VBR Mode with changed ‘MinQp’ and ‘MaxQp’ the output
bitrate could be complete different.
Only a
vailable with ‘’Bitrate control=vbr’
Package
Specifies different Multiplexer Mode for Decoder compatibility.

Buffer Mode
Specifies the Ethernet Packet Size:
188x7 = 7 TS Packets/ Ethernet packet = 7 x 188 = 1316bit
188x6 = 6 TS Packets/ Ethernet packet = 6 x 188 = 1128bit
