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.
