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.   
The Proportions field has two settings: 
  Standard – Square pixels for a VGA monitor 
  CCIR-601 – Elongated pixels for a TV monitor 
Click the setting that reflects the type of display on which your viewers will view your content. 
For example, if you want to stream your video on the Internet for the user to view on a 
computer monitor, select Standard. If you select an inaccurate setting, your video will be 
distorted 
4.   
In the 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.
