This week’s lesson number one gave me an insight into Roto. Another use for drawing in a Roto node, another Roto node differs in that this node is paintable and I can easily clean up unwanted objects in the scene with a brush, just like an eraser, for quick erasing.
In today’s lesson we learn how to clean up a scene in three different ways with Roto paint.
In this method you first select a frame, use the clone tool in the Roto paint node, match the colours to erase objects on the same frame, then use the Roto node to rotate the object area and track the objects. Because everything cloned is in one frame, we need to use the Frame Hold node to hold this frame throughout the video so that the objects don’t appear. The next step is to create a match move node in the tracker and connect it to the Frame Hold. The final step is to create a Regain node to place some textures to make the area look the same as before.
This method creates the text on the object, we use the same method as the third and create the corner pin, but we need to invert it to enlarge the text area as we can easily design the area. After we have edited the text, it can be displayed on the object
This method starts with a Rotopaint node, then holds the frame, then tracks the object using the plane tracker, then we need to create a corner pin to connect the frame holding node and reacquire it.
