WMV

WMV 8/9 Profile: Enables you to select a Windows Media 8 or 9 profile to define the quality and frame size of the video output. A higher bitrate profile yields better quality (and often higher resolution), while a lower bitrate produces smaller file sizes.

Custom WMV Profile: Selecting this option causes a dialog to be shown when the merge operation begins. The dialog provides options for manually configuring a custom WMV profile that can use any desired WMV version, resolution, bitrate, etc. This is very useful when a profile is not available with the desired bitrate and resolution combination. The dialog also allows profiles to be saved for later access.
