Video & Audio Settings

Regardless of the encoder type, all types require you set the audio and video properties. These values

are the same for all encoder types except for the added color space setting for AVI and Flash

You can enable or disable video and/or audio by clicking the check box next to Source: When

enabled, the Source, Input, Signal, Proportions, Size, and Input fields can be edited.

Although the Niagara Pro is a two channel encoder, meaning you can only capture from two

physical audio and video sources at any given time, you can capture multiple streaming formats and

resolutions simultaneously from the same video source. To accomplish this, the video source is seen

as multiple inputs denoted by incrementing decimal values. They appear in the following manner:

• Osprey 5x0 Video Device 1.1

• Osprey 5x0 Video Device 1.2

• Osprey 5x0 Video Device 1.3

• Osprey 5x0 Video Device 1.4

Warning: Ensure all of the encoders using the same video Proportion and Size settings also use the

same video and audio source settings. For example, all encoders capturing at Standard proportion

and CIF size are set to Osprey-5x0 Video Device 1.1 while encoders capturing at Standard

proportion but QCIF resolution are set to Osprey-5x0 Video Device 1.2.

Set Input for both video and audio to match the connectors on the back of the Niagara Pro to which

you have connected your video and audio source. This would be either Composite, S-Video or SDI

for video input and Unbalanced, XLR Balanced, XLR AES/EBU or SDI for audio input.

When you performed the First Start Setup, you determine if your video signal was NTSC or PAL.

The Signal field adds granularity for regional NTSC, PAL, and SECAM settings. If you are

uncertain which setting applies, refer to the owner’s manual for the video source you have connected

to the Niagara Pro hardware.

The proportion setting uses the term Standard, meaning square pixels for a VGA monitor, and

CCIR-601, meaning elongated pixels for a TV monitor. Choose the setting that reflects the type of
