(if present in the input signal) into H.264/H.265 (HEVC) SEI message. Native
CEA-608 and 608 over 708 captions are both supported. It is off by default.
Note that it is only supported by SDI product.
Output: by default, it is 1280x720, 30fps, 2Mbps. Sub stream outputs at
640x360p30, 3Mbps for NDI |HX3.

Bitrate Encoding: options are CBR (default) and VBR. Live stream at CBR
(Constant Bitrate) for bandwidth stability. VBR(Variable Bitrate) files vary the
amount of output data per time segment. CBR is the only choice for
NDI |HX3. And you need to set quantization parameters for VBR. The
quantization parameter controls the amount of compression for every
macroblock in a frame. Large values mean that there will be more
compression, lower quality, and lower bandwidth. Lower values mean the
opposite.
■
®
Min QP: available when Bitrate Encoding is VBR. The range of values is
0 to 50. The default value is 4. And we recommend you use the default
value and do fine adjustment if needed.
■
Max QP: available when Bitrate Encoding is VBR. The range of values is
1 to 51. The default value is 40. And the value must be larger than the
Min QP value. We recommend you use the default value and do fine
adjustment if needed.
■
Code type: options are H.264 (default) and H.265(HEVC) encoders. H.264 is
the only choice for NDI |HX3.

®
Encoding profile: for H.264 encoder, the profiles can be High
