Hi,
Usually, if you're dealing with moving data around a Cairngorm application, you would create a public variable (or VO) in the ModelLocator. When you take a snapshot of the video, dispatch a CairngormEvent that contains the bitmapData (I would do this in the view's script; not a ViewHelper). In the command, update the variable in the ModelLocator with the data. Now you have the data in a centrally located position. If another view needs access to this data, simply bind the view's control to the variable in the ModelLocator. As soon as the variable is updated by the command, the second view will automatically reflect the change.
This is a simple explanation and may not fit your particular use case. But hopefully it will give you some ideas.
