The class started off by talking about blur, so the right way to blur things is not by using the blur node but to use defocus. The difference between them is that defocus works like a lens when the object is not focused we get a bokeh effect that’s how defocus works but, blur on another hand just blurs out everything.
ZBlur with the help of the ramp give a gradient blur on a plate but it is only in a 2D space, but ZDefous works in a 3D space there is a small dot on the screen that says focal point that point can move and that can be dragged anywhere in the 3D space to make focused, and there is more potion in ZDefous like to add depth of feed. After changing the output setting to focal plane setup it will help you to identify which place is focused and which is not. I felt was really nice.
We later moved on to Roto Paint, this node is used to clean up and clone out objects in the plate. The Roto Paint is a blush tool for painting on a plate. There are different options you can change under roto paint like transform, motion blur, shape, stroke, clone, lifetime, tracking and node. We show a few potions under strokes like the brush size, spacing and write on start and end.
How to roto paint to clean up, first we will have to use the roto paint tool to clean up the area, then use a roto to draw a box around the clean up the area and then premult the patch, later add a frame hold to the same frame where clean up was done, add a tracker and create a transform match move so that the clean up can be seen throwout the video.
So for our homework, we had to clean up a video.
We also had to complete our balloon festivals project.
