Softimage’s Stephen Blair shows a new scripting feature in the new 2013 version of Autodesk Softimage where you are able to set the codec for the viewport captures which is now set as a scriptable parameter.

Stephen Blair notes: In 2013, you can use the ViewportCapture.DSCodec parameter to set the codec. To get the coded value, just do a viewport capture and set the codec; the DSCodec value will be logged to the script history.
