To configure video settings:
1. In the Source field, select Disabled or Osprey-700 HD Video Device 1 .
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 encode 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 Input field, the video input is SerialDigital .
3. The Proportions field setting is Standard (square pixels for a VGA monitor).
4. In the Size field, select the pixel size of the encoded video. The standard sizes include:

HD 1280x720

CIF for video scaled from full-size to ¼ size

QCIF for video scaled from full-size to ¼ of CIF size

Custom
Customization is useful when you are 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
the resulting video to be (Figure 90).
