This week in Nuke we learnt about removing specified objects from videos and how to use the new nodes.
The Denoise node is an efficient tool for removing noise or grain from your footage. It uses spatial or temporal filtering to remove noise without losing image quality.
To remove the specified image from the video, we first need to denoise the original video. This will better save video resources, then use the RotoPaint and Roto tools to erase and frame the parts that need to be removed to create an alpha layer.
After that, the created layer is blurred and tracked, and finally a frame hold is applied. Let the newly created layer overwrite the original video.
