Video source settings

Advanced - MPEG-4 settings

These are tools for adjusting the MPEG-4 settings and for controlling the video bit rate.

The MPEG-4 standard provides many different coding tools for various applications in different situations. As most MPEG-4 clients do not support all these tools, it is usual to instead define and use subsets for different clients or groups of clients. These settings allow you to define the type of client to use.

Under Client Compatibility, select the correct combination of Video object type with the ISMA compliant option to use for your viewing client.

The GOV Settings describe the composition of the MPEG-4 video stream and this format's basic elements.

The GOV Structure can take two different forms; I or IP, which describe the type of images included in the video stream, as well as their internal order.

The GOV Length determines how many images of the one type (I or P) are sent before the next type is sent.
