2. Each filter has independent settings for cropping, default output size, watermarks, and
captions that you can store between sessions.
NOTE: Compared to the previous pin-based method, no requirements exist for a particular
startup order, to associate settings with instantiations.
If you are familiar with GraphEdit, you can best visualize SimulStream filters where you:
 Construct a multifilter graph with GraphEdit.
 Apply different crop, watermark, and caption settings to each filter.
The Enable Checkbox
The checkbox at the top of the group (Figure 99) turns on SimulStream for the currently selected

mode.
You check the Enable check box
The text indicates that SimulStream
evaluation mode is enabled.
A message box prompts you to restart the system when you change the SimulStream Enable
status and click Apply or OK. ViewCast strongly recommends that you do so. If you do not,
SimulStream may partly work but the filter names and their pins may remain incorrect without a
restart.
When you enable SimulStream (or SimulStream evaluation mode), the driver always works in
Postprocessing mode, as described in the mode control group. In this case, the system forces
the mode control to Postprocessing mode and disables the Direct mode control.
