To configure video settings:
1.
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.
2.
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.
3.
Select the Proportions setting from the drop-down list.
 Standard – Square pixels for a VGA monitor)
 CCIR601
4.
In the Size field, select the pixel size of the encoded video from the pre-determined sizes in
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 64).
Note: The size in the Width and Height fields must be divisible by 2.
