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 are 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.

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>.

NOTE: Please make sure the higher compression ratio is supported by system before setup.
