Profile 6
Profile 7
Profile 8
Note: Non-recording profiles (streams) are I-frame only.
Note: Each stream can have its own independent profile which does not need to be shared
with other streams.
Active profile
Each stream shows its active profile. When you click the name, the Encoder Profile (stream
(number), profile (number)) window appears. Refer to the chapter Encoder Profile, page 31
for details.
Video resolution
Select the desired resolution for the video image.
Note: Each stream can have its full resolution.
Encoding interval
The Encoding interval slider determines the interval at which images are encoded and
transmitted. This can be particularly advantageous with low bandwidths. The frame rate is
displayed next to the slider.
Click Test to see when and if a specific stream will drop frames.

Encoder Regions

User can configure encoding regions for every configured preset (preposition/scene), to
increase or decrease the encoding quality for selectable areas of the video image. These
regions give better control of the bit rate. Important parts of the scene (identified as objects
in the GUI) are encoded at high resolution and therefore have an enhanced encoding quality.
Less important parts (such as the sky and trees in the background, all identified as
backgrounds in the GUI) are encoded at lower quality and therefore have a decreased
encoding quality.
Eight encoder regions can be defined.
Eight encoder regions can be defined. To define encoder regions, follow these steps.

From the first drop-down box (the unlabeled Regions selection list), select one of the
eight available regions. (The drop-down box has the default option of Region 1).
Click the + box to add an area.
Use the mouse to define the area (shape) that the region covers and to position the area
(shape) in the preview of the video image.
– Drag the center, corner points, or sides of the shaded area (shape).
– Double-click a side to add additional points to the area (shape).
From the last drop-down box (the unlabeled Mode selection list), select the encoder
quality for the defined area. (The drop-down box has the default option of Default).
For unimportant parts of the video image, select Background.
For important parts of the video image, select Object.
(The quality levels for Background and for Object are defined in the Expert Settings
section of the page Encoder Profile.)
Description
For an SD image, the video bit rate and frame
quality are adjusted to ensure that the bit rate is
the priority.
Ideal for encoding on a DSL uplink where bit rate
limitations are critical.
Ideal for encoding on a 3G uplink where bit rate
limitations are critical.
