RATE CONTROL (ADVANCED)
Selects the encoder rate control mechanism. VBR (Variable Bitrate) means that the encoding bitrate can fluctuate
within the bitrate statistical period. CBR (Constant Bitrate) means that a stable encoding bitrate is ensured within
the bitrate statistical time.
QUALITY MODE (ADVANCED)
Low Latency, Balanced, High Quality
Low Latency optimizes encoder settings for latency at the expense of quality. High Quality optimizes settings for
quality at the expense of Latency
INTERLACE MODE (ADVANCED)
In the case of interlaced input, this selects how the unit formats the output stream. In Combined mode the top and
bottom fields are combined into a single frame. In separated mode the fields are set separately for an HEVC
stream. Decoders will need to support field separated mode.
Separated mode is not available for H264.
VIDEO BIT RATE
Textbox for entering video bitrate. For example:
1M = 1,000,000 bits per second
1000k = 1,000,000 bits per second
2.5M = Not a Valid Format
Used on RTP, RTSP and RTMP only.
FRAME RATE
Used to encode at less than the input frame rate, (for example, an input frame rate of 30fps with Half selected
would cause an output stream of 15fps). If interlaced input is used, then this is used to reduce the number of fields
being encoded.
GOP SIZE
I-frame frequency. The number of frames in each Group of Pictures (GOP)
