This tutorial attempts to explain how the 2d motionblur works in Nuke. It will beggin by doing some basic keying of a Chinese Fighter Jet, then follow into achieving motionblur using a transform node, motionblur2d node and the Vector blur node.
Note: I aplogise in advance for my nasally tone. Please bare with it as I have a cold!
