PointCloudKeyer

Instructions

1. Connect the Src input of the PointCloudKeyer into your foreground footage. (Optional: connect a background plate to composite later)

2. Create a roto node and hook it into the Shape input

3. With the View set to ‘Point Cloud’, select a color space that does a decent job separating out the screen color you want to key, Chroma Red/Blue should work for most cases. (Optional: connect the custom input a 2D color space image and set the color space to “Custom” to use your own input)

4. Adjust the point cloud using the translate and scale knobs, if needed.

5. Draw a roto shape around the screen color you want to key

6. Preview your output by changing the view to “composite” or “final result” (Optional: use the “dense point cloud” and “overlay point cloud” to help place a roto shape that works well for your shot
