This week we learnt to introduce how to use projection nodes in Nuke to composite new items and make replacements, patching or adding content to the image through the item nodes.
The main method of adding images from the video is to use the projection method. First, the camera frame is fixed in the position to be replaced and ROTO is performed. The part we can roto uses the projection camera to map certain frame information to the 3D card. Then a new camera is created and the whole image is rendered again using the tracking camera
We can adjust the colour by using the grade node
