To configure video settings:
1. In the Source field, click a device from the drop-down list:

Osprey-700 HD Video Device 1

Disabled
Note: Because the Niagara 4100 is a single-channel encoder, you can only connect and stream
one audio and video source at any given time. However, you can stream the same audio
and video at multiple data rates and multiple formats to provide the best user experience
for different viewing audiences.
2. In the Size field, select the pixel size of the encoded video. The standard sizes include:

HD 1280 x 720

Full-size for full screen video

CIF for video scaled from full-size to ½ size

QCIF for video scaled from full-size to ¼ size

Custom

capturing video to be played on a mobile video-device that requires a non-standard size for
compatibility.
When you click
Custom , two additional fields appear so you can enter the exact size you want
