value. However, the shorter the GOV length the better the video quality is.

1 On the Streaming tab, click Video format in the menu on the left.
2 In the GOV Settings section, type the values in the GOV Length boxes.
Range: 1 to 255.
The default value for H.264-1 / H.264-2 / H.264-3 / H.264-4 is 60 / 60 / 30 / 30 (NTSC)
or 50 / 50 / 25 / 25 (PAL).
