Tap the encoder icon to display the Encoder page. Use this page to define the settings that you want to use to prepare the video for output.

When you have selected the appropriate settings, tap the Back icon to return to the main page.

Setting Description
Video Format

Defines the resolution of the video file.

Select the format that you want to use from those available (Auto, 720p, 1080i, 1080p, 1080p (3G)), and then tap Done.

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, and tap Done.

The camera back transmitter only supports 4.2.2 in HD and 4.2.0 in 3G‑HD.

ASI Out Indicates whether the output format is an ASI signal.
Video Delay Mode

Defines whether to use ‘Super-Low’ or ‘Low’ video encoder latency. Select the delay mode that you want to use, and then tap Done.

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.

Refresh Rate Defines the number of times a still frame is shown or refreshed per second. Tap the current value, set the required value by pressing the upper and lower boxes, and then tap Done.
Entropy Coding Mode

Defines the coding option (or algorithm) used to generate H.264 or MPEG-4 AVC (Advanced Video Coding) video content.

There are two coding options available: Context-Adaptive Binary Arithmetic Coding (CABAC) and Context-Adaptive Variable-Length Coding (CAVLC).

CABAC is the recommended setting, and you should only use CAVLC when directed to do so.
