This semester Nuke’s first class, Mr. Gonzalo, taught us how to remove excess items from our videos.

The first step in removing excess items from a video is to denoise the original video. This will save the resources of the video better

Then use the RotoPaint and Roto tools to erase and frame the parts that need to be removed to create an alpha layer.

Afterwards, the created layers are blurred as well as tracked, and finally a frame hold is applied. Let the newly created layer overlay the original video.

After that, the teacher gave us how to remove the tracking points on the faces of the characters in the movie. The teacher taught three main methods. But the principle is all by eliminating tracking points from one video. After that, this clear and clean original video is superimposed on the existing video.

The main thing I learned in this lesson is the basic method for video clearing elements. In some cases, I found that simple fusion does not work very well. It is still necessary to make the right choice for the elimination method according to different environments and different video elements
