Video & Audio Settings

The properties page for each encoder type uses the same Video and Audio Settings except for the added color space setting for AVI and MPEG-4.

You enable or disable video and/or audio by clicking the check box next to Source: When Source is enabled, the Source, Input, Signal, Proportions, Size, Format, and Input fields can be edited.

Source: This field displays a drop-down list of devices available on the encoder. The Cisco Digital Media Encoder 2200 is a two channel encoder, so there are two physical sets of audio and video inputs can be used at any one time. However, you can capture multiple streaming formats and resolutions simultaneously from this one set of video inputs. Video source is seen as multiple inputs denoted by incrementing decimal values. They appear in this 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

Set Input for both video and audio to match the video and audio inputs on the back of the encoder to which you 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 determined 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 that you have connected to the encoder.

The proportion setting uses the term Standard, meaning square pixels for a VGA monitor, and CCIR-601meaning elongated pixels for a television monitor. Choose the setting that reflects the type of display on which your content will be viewed. For example, if you will be streaming your video on the Internet to be viewed on a computer monitor, select Standard. Selecting the incorrect setting can make the streaming video appear distorted.

The Size field refers to the pixel size of the encoded video. The standard sizes are as follows:

•Full for full screen video

•CIF for video scaled from full size to ¼ size

•QCIF for video scaled from full size to ¼ of CIF size

You can also specify a custom size for your video. This is useful when capturing video to be played on a mobile video device that requires a non-standard size for compatibility.
