Advanced Animation Timing for CG



The Time Filter is an animation timing tool for CG productions, designed to give CG animation 2D-style timing with ease. It was used in such productions as the XPICE music video, Samurai Frog Golf, and ONI: Thunder God’s Tale among others, and was featured at SIGGRAPH 2023 as the opening presentation of the Advances in Animation Tools session.



This video explains the basic operations of the Time Filter. See how to set up a filter, how to apply a camera offset with a simple demo scene, and how it is used in an actual production.

This video delves deeper and goes under the hood to discuss the methods, the construction of the filters, and the math behind the camera offset network. This video is meant for advanced users and technical teams.
