Channel Setup

Lecture Recorder x2 User Guide

Video signal type

Select the video signal type coming from the S-

Video source:

- S-Video

- Composite

Frame size

Select a Frame size from the drop-down list to

limit the width and height of the video image. If

the analog video source is sending resolutions

larger than the resolution limit they will be

scaled to the resolution limit. Limiting the frame

resolution can help to reduce bandwidth usage.

Show time label

If the analog video needs to be time labeled, use

this parameter to specify how the date and time

will be displayed.

Use the Format substitutions commands to

select the necessary date and time format. The

commands are described in table 7.

Note: This option is available in the Independent

Streams mode only.

Key frame interval

Controls the number of seconds between key

frames.

Note: This option is available in the Independent

Streams mode only.

Limit frame rate

Enter a value in terms of frames per second.

This field is used to set a frame rate that is

lower than the maximum frame rate at which

the Lecture Recorder x2 can capture images.

Reducing the frame rate reduces the number of

images being captured by the device.

Decreasing the frame rate can help to reduce

bandwidth usage.

Note: This option is available in the Independent

Streams mode only.

Bitrate

Enter the signal bitrate. A lower bitrate

produces lower quality videos and smaller file

sizes. A higher bitrate produces better quality

videos and larger file sizes.

Note: This option is available in the Independent

Streams mode only.
