Figure 24. Video tab

To configure video settings:

Select the video input Source from the drop-down list.

Note: When SimulStream is enabled, you may use the same input source in another encoding

profile. This lets you encode the same audio and video at multiple data rates and multiple

formats to provide the best user experience for different viewing audiences.

In the Input field, select the video input.

IMPORTANT! The video input must match the connectors on the back of the system and your

video source.

Select the Proportions setting from the drop-down list.

 Standard – Square pixels for a VGA monitor

 CCIR601 – Elongated pixels for a TV monitor

In the Input Size field, select the pre-determined size of the encoded video from the drop-

down list.

You can also specify a custom size for your video. This customization is useful when you are

capturing video to be played on a mobile video-device that requires a non-standard size for

compatibility.

When you click Custom, two additional fields appear so you can enter the exact size you want

the resulting video to be (Figure 25).

Note: The size in the Width and Height fields must be divisible by 2.
