Paint-Out

RotoPaint/Compositing

About The Project

Basically, I wanted to erase the people sitting and standing on the right. For some added purpose, I incorporated Jupiter into the sky. Let's start with the planet.

First, I tracked the camera with Mocha. Using the camera's movement, I rotoad the image of Jupiter and graded it. Still using the camera's movement, I stabilized and rotoad the church and the statue. Why not keying? Because I wanted to have a consistent edge. And also, for the extra time it's going to take me, I'm saving some with the bugs and tweaks that keying makes. I also did a little cloud roto over the planet (to add some overlay/realism). I then screen-integrated my element into the original plate.

Then, for the paint-out, I started by transforming my camera movement into a 3D scene. I then used the ModelBuilder node to model the environment of the elements I wanted to remove. With this, I frame-holded my sequence to paint-out the people. I could have exported my image to Photoshop and removed it quickly and easily. But I wanted to have full control of the paint-out at all times. I then projected my correction onto the cards. With a little grading to match the change in luminosity, I rotoed the fence to get it in my final shot.

Software Used

  • The Foundry's Nuke
  • Boris FX's Mocha

    Key Tasks:

    • RotoPaint
    • Rotoscopy
    • Grading
    • Match Move
    • Integration

Challenges:

Originally, my 3D tracking was on Nuke with a CameraTracker, but the solve wasn't perfect... On several occasions. I came very close to making my trackers manually then putting them in my CameraTracker. But, as a last resort, before delaying my entire project, I tested Mocha's camera solver. In less than 2 hours, I managed to get a perfect solve.
