Device video advanced settings can be changed on this page.MEDIA PROCESSING UNITThis value, PAL (1..50), NTSC (1..60), indicates the I-frame interval withregards to the defi ned frame rate setting. A value of n will result inI-frame being generated every n th frame, i.e.n = 1 --> GOP = IIIIII....n = 2 --> GOP = IPIPIP....n = 3 --> GOP = IPPIPPIPP...Consequently the number of I-frames per second is dictated by theframe rate setting. With e.g. n=3 the result is following:Frame rate = 25 --> 8 I-frame per secondFrame rate = 3 --> 1 I-frame per secondI/P frame size (100...1000 %). Used only in CBR mode. This valueprovides the I-frame/P-frame size ratio (how much bigger I-frames arethan P-frames in per cents).
