TUTORIAL: GETTING TO KNOW YOUR CISCO DIGITAL MEDIA ENCODER 2000
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
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. If the inaccurate setting is
selected, your streaming video will be distorted.
The Size field refers to the pixel size of the encoded video. The standard sizes are as follows:
• Full-size for full screen video
• CIF for video scaled from full-size to one-fourth size
• QCIF for video scaled from full-size to one-fourth 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. If you select Custom
from the drop-down menu, two additional fields will appear allowing you to type in the exact size
you want the resulting video to be.
NOTE: If you specify a video size incompatible with the color space of your source video, Cisco
Digital Media Encoder 2000 will automatically correct the size to the closest compatible setting
when you click the Submit button. The color space format setting is only available in AVI and Flash
encoder properties and appears as an additional field under the Size setting (see below).
Now that you have completed all of the Video and Audio settings, you can proceed to the encoder
type settings at the bottom of the page. As previously stated, these settings will vary according to the
encoder type.
Advanced Streaming Settings
SimulStream and DirectShow Filters
Filters have two interrelated purposes, as follows:
• They allow applications to enumerate and list DirectShow video capture and preview pins or
streams (each with different settings) as named entries in their video device select lists. The video
device driver can be configured to show 1 to 10 filters per device. Each filter has one preview pin
