Advance encoder settings

Refresh Settings

Refresh: Defines the number of times a still frame is shown or refreshed per second.

Use ‘Slow’ or ‘Fast’ for longer latencies and choose ‘Fastest’ for shorter latencies.

Direction: Vert/Horiz

Quantize: Recommended setting is ‘Auto’.
Note: Uniform and (QP) Range are advanced settings for engineering only.

Quantize Range

The quantization parameters govern the accuracy values. A lower quantization parameter results in a better picture but higher bit-rate. The recommended setting is ‘Auto’.


Latency

For each SDI input, latency can be defined using the controls, CPB and slices.

CPB: This is an advanced setting that allows you to control the size of the encoder’s Coded Picture Buffer.

Slices: Use this setting to control subframe encoding, which cuts down latency by pipelining slices instead of frames.

Chroma

Chroma subsampling is a method for compressing color data in a video signal or file. It reduces the amount of color information in the signal to allow more luminance data instead and allows you to maintain picture clarity while effectively reducing the file size by up to 50%. Select the ratio that you want to use.

The Mini-Tx UHD supports 4.2.2.

Video Delay Mode

Defines whether to use ‘Normal’, ‘Low’ or ‘Ultra Low’ video encoder latency.

Note that you must ensure that you set the correct Video Latency setting on the receiver, which depends on the Video Delay Mode that you select here. If latency is set incorrectly on the receiver, the image may freeze or judder.
