Import multiple 2D tracks as transform nodes

Posted in: NUKE from The Foundry
Hi everyone!

I’m facing this problem: I have hundred of 2D points created in other tracking package and I need to import them to Nuke to aid with roto – probably as Transform nodes.

To be clear: I don’t mean any 3D pointcloud or any camera track. I’m talking about pure 2D tracks.

I can export them out of my tracking package in any way you can imagine, so exporting is not a problem.

Problem is how to get this to Nuke without manually creating 100 Transform nodes and manually importing ascii text files into them one at a time.

I guess it will need creating a python script that goes through text file with all my 2D tracks (formatted in example like Track1 framenumber Xpoxition Yposition), creates Transform nodes for all trackers and copies the XY position information to them…

Any suggestions on what to use as a starting point? I actually can’t do any python for Nuke at all so I will have to find someone to do it for me 🙁

Somebody got any other ideas? Some alternative approach?
Somebody willing to help please?

Thanks very very much guys.

Petr
