How to Edit some element(e.g. keyframe, camera direction)of walkthrough by Dynamo

hello.

I am looking for way to edit the walkthrough elements on dynamo.
I got some references such as Dynanimator. This can create various animation but not revit walkthrough path or related it.

what I really want to do is to parametrically edit the revit walkthrough and its element by the dynamo or other plugin.

how can I get start?

Thank you.
