Shot A13: Early Composites

I pulled a quick chroma key with Nuke's IBK Keyer and created a garbage matte for the background that tracks to follow the alley wall. The wall geometry that was created during the matchmove now exists as a 3D card in Nuke with a texture file of clean brick applied to it. Being able to color correct and edit the wall patch on the fly is much better than re-rendering out image sequences from Maya every time I need to change something.

Shot A13: Matchmove

I recently began work on the sister shot of A13_05, a wider shot down the alley that reveals the full extent of the 1930's backdrop. I decided to use PFTrack instead of Boujou to create the matchmove, as I have been hearing good things about it recently. Here is a video of the final result.





As this was my first solve with PFTrack I went very methodically and took my time, reading through the manual and additional literature. Over all I spent about 3 hours to create the solve. PFTrack can export camera data straight to Nuke, which allows me to bypass using Maya to position 3D geometry and rebake the camera. Here is a screengrab of my workspace in Nuke.
