Audio/Video: Normally for outputting a stream containing both audio and video, leave this at

“Both”. For encoding a video input without embedded audio, set this to Video Only. You can

also discard the video stream and only transmit audio by setting this to Audio Only.

Analog audio for SDI input (QVENC): Setting this to Yes will embed the audio from the

analog input instead of trying to use audio embedded in the SDI signal.

Note: For SDI input without embedded audio, the encoder will not start with Audio/Video set

to Both. This must be set to Video Only for the encoder to start, or alternatively, you can set

Analog audio for SDI input to Yes.

Video Filtering: Enabling this pre-filter to the video input may improve encoding efficiency.

Video Frame Rate and Resolution: Normally, the encoder automatically detects the frame

rate and resolution of the video input signal. Setting these values allows you to override the

original input signal to reduce the frame rate and/or resolution, enabling very low output

encoding bitrates, such as for broadband wireless connections.

D1/Half/CIF/QCIF Progressive Output: Setting this to Yes will cause the output stream to

progressive scan, even if the input was interlaced. This may improve the video quality for

lower-resolution video.
