Pearl-2 User Guide Configure video encoding
Item Options
Main: Choose this option for standard-definition broadcasts.
High: This is the default. Choose this option when video is viewed for
broadcast and disk storage applications, particularly for high definition
television application such as Blu-ray disk storage format and HDTV
broadcast service.
3. Configure the frame size, do the following:
a. Uncheck Use current signal resolution as the frame size.
Enabling Use current signal resolution as the frame size is not
recommended if the video input resolution changes frequently. An unstable
cable or other disturbance that causes the resolution of the video input signal
to change during a live stream can cause the stream to drop. Unchecking this
feature helps prevent that.
b. Select a Frame size from the list of options or enter a custom frame size in pixels.
4. Change the Limit frame rate. The default should be adequate in most applications. While decreasing
the limit may improve system performance, you may need to test different values to balance video
smoothness and processing power
5. Change the Bitrate. If using H.264 video codec, you can increase or decrease image quality by
increasing or decreasing the target Bitrate value. Video with a high level of motion and high resolution,
such as a sporting event, requires a high bitrate.
6. Click Apply.
