This week’s teacher focused on Nuke’s projection function. Firstly, the teacher introduced projection in a simple way.

This week we focus on how to use projection nodes in Nuke to make quick replacements of objects in videos.

A quick way to replace items in a video is mainly to use the projection method. First, the camera frame is held at the place to be replaced and ROTO is performed, then the Roto part is projected on the 3D Card. A new camera is then created to playback the projected image. This way the scene that you want to replace or delete can be processed clearly.

Then we learned about the HueCorrects node, which helps us to precisely adjust the saturation of the hue and adjust the curve to make precise changes to the color.
