Video tab
Flash adds some additional frame and bit rate controls. The frame rate changes the frames per second
that the video will be encoded. You can use the audio format setting to modify the audio frequency and
change stereo to mono. The bit rate settings pertain to the amount of data per second the audio and
video are captured. Decreasing the bit rate for both or either decreases the playback viewing quality.

To configure video settings:
1. In the Source field, the default is 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:

Standard

Widescreen

Custom
You can also specify a custom size for your video. This 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 63).
