Pearl Mini User Guide Configure video encoding
Setting Description
l overall system load affects the ability for the device to process pixels;
l available network bandwidth;
l the source and stream frame size (resolution);
l the type of motion that is captured; and
l number of users accessing the stream.
When adjusting the frame rate, you may need to try different values to achieve the best outcome.
Bitrate
In general, higher bitrates mean higher image quality, but more bandwidth is needed for streaming
and video recordings are larger. You can set the bitrate to improve the image quality (this does not
work with Motion JPEG encoding).
For example, an HD Blu-ray video is typically in the range of 20 Mbps, whereas a standard-
definition DVD is usually 6 Mbps.
If you're unsure what bitrate value to use, start at 5000 kbps (slightly less than a typical DVD) and
test to see how this looks for your viewers.
