Because the 'tracks' knob isn’t exposed as an Array_Knob (or a subclass
thereof), it doesn’t have .copyAnimation()/.copyAnimations() methods. And
because there isn’t another Python interface to the new Tracker, you’ll need to
loop through your CornerPin keys and manually set keys at the cell indices
you’re interested in (x pos = index 2, y pos = index 3 for the first track).

Subject: [Nuke-python] Python in new tracker node.
Hello! I was am trying to copy over cornerpin data into a new tracker node w/
4 tracks that have the copied animations. I'm running into issues trying to
python with the new Tracker node. I finally figured out how to add a track
with .execute() but now I need to copy over an animation curve into the newly
created tracks.
Here's the code I am working on. How do I get python to assign the added track
to a variable? then How do I copy that animation over? I couldn't fine any
documentation about working with the new Tracker node.
cornerPin = nuke.selectedNode()
c1 = cornerPin['to1']
tracker = nuke.createNode('Tracker4')
tracker['add_track'].execute()
t = tracker['tracks']
c1.copyAnimations(t.animations(t['track_2']))
Thanks.
