GOV Settings
Users can set the GOV length to determine the frame structure (I-frames and P-frames) in a
video stream for saving bandwidth. The setting range is from 2 to 64. Default value is 60,
which means there's one I-frame every 60 frames. Longer GOV length means lower I-frame
frequency. The default value for H.264-1/ H.264-2/ H.264-3/ H.264-4 is 60/ 60/ 30/ 30. Click
on <Save> to confirm the GOV setting.
H.264 Profile
Users can set each H.264 Profile to <Baseline Profile>, <Main Profile> or <High Profile>
according to its compression needs. With the same bit rate, the higher the compression ratio,
the better the image quality is. The default setting is <Main Profile>.
