Video capture from dynamo

Hallo guys,
I am struggeling recording an out put of a node in dynamo.
is there a way to get a realtime millisecond update in dynamo ?

Another question:
I want to know which library shall I install to get these referances.

if not how can I get events like this one
ViewModel.RequestViewRefresh += ViewModelRequestViewRefreshHandler;

or referances like these
using Dynamo.Wpf.Extensions;
using Dynamo.Wpf.ViewModels.Watch3D;
using Dynamo.Graph.Workspaces;

in a brief way: the accessiability to the Dynamo viewport classes.

Looking forward for your feed backs. would be high appreciated !

_Thanks Ghaith
