Hi!
Is it possible to export just the 2d tracking data from a couple of trackers? I've tracked an object that needs som clean up and retouch, and I know that I can import tracking data (using fusion mostly but from time to time I go into Nuke). And I can see, in the scene export node, that there is "3d position" - "2d projection" - "2d paths". But only "3d position" is available to use, the other ones are greyed out. Do I need to do something special to get these options?
At the moment, all I got is a couple of tracking points, no solve of any kind. I figured I didn't need that since I'm only interested in the 2d tracking data :)
Hi Jonas,
The data that you can export is defined by the export format you choose in the Scene Export node, so for example, FBX allows you to export 3d positions, but not 2d projections or 2d paths, which is why these options are greyed out.
PFTrack allows you to write custom export scripts using Python that can export any camera or tracking data passed down the tree. For example, in the Files category in this forum we have an example script for download that exports 2d trackers in the “Discreet trackers” file format.
If you are looking to export 2d tracker data in a specific format, you may need a custom export script that writes the data in a format that is compatible with whatever application you are using to read the data. If you are using both Nuke and Fusion you would probably need different export scripts for both those applications, unless they share a single file format that can represent 2d tracker movement.
