What is UI stands for??what is IK ,FK??
is there any tutorial for audio recording and LIP SYNC to the recorded audio
UI - User interface. Buttons and inputs and such.
FK and IK are Forward and Inverse kinematics, which I'm sure Wayne talks about in this course but it may be a later video. He also has a full course on lip sync: https://cgcookie.com/course/demystifying-lip-sync-animation
Hope that helps!
