Set <High>, and bitrate will vastly be reduced; however, image
quality may be degraded at the same time.
Set <Low>, and bitrate will stably keep low while image quality
remains high.
- Dynamic GOV
According to the amount of motion in the application area, the GOV
length of the video will be adjusted dynamically to reduce more
bitrate, especially for scenes with minor changes. The length of
Dynamic GOV is from <GOV Length> to <Max. GOV> (4094).
Select <Enabled> and set <Max. GOV>. Then, click on <Save> to
activate the setting.
If there is small or zero activity in the scene, set <Max. GOV> larger,
the GOV length will be longer, resulting in lower bitrate and
bandwidth.
If there are constant dynamic changes in the scene, it is suggested
just adjust <GOV Length> and disable <Dynamic GOV>.
Click on <Save> to confirm the setting.
