Overview

This video tutorial demonstrates the new inbetweening feature in Cascadeur 2025.3, explaining how it functions as an interpolation type that updates in real-time and can be combined with other interpolation methods. It covers scene setup, adjusting interpolation types for different body parts, utilizing FK keyframes, integrating Mixamo animations, and setting up constraints for objects like a soda can.

Key takeaways

• Inbetweening as Interpolation: Cascadeur 2025.3 introduces inbetweening as a real-time, updateable interpolation type that can be used alongside other methods.
• FK vs. IK Keyframes: Understanding the difference between FK (Forward Kinematics) and IK (Inverse Kinematics) keyframes is crucial. FK keyframes are posed relative to parent joints, preserving poses when other joints move, which is essential for combining with inbetweening. Default IK keyframes are in global space.
• Track Separation: Updated rigs with separated body part tracks provide better results with the new inbetweening system. It's recommended to update rigs using the quick rigging tool.
• Adding Keyframes: Additional keyframes can be added within an inbetweening interval to further specify poses and prevent issues like hands passing through surfaces.
• AutoPhysics Integration: Inbetweening can be used with AutoPhysics, which can correct the character's center of mass trajectory and add secondary motion for more dynamic animation.
• Mixamo Animation Workflow: Mixamo animations can be imported and rigged, with specific body parts' keyframes set to FK for retaining their poses while inbetweening the rest of the body.
• Object Constraints: Constraints can be set up to make objects (like a soda can) follow specific body parts (like a hand) by creating a joint, parenting the object to it, and constraining the joint to the desired body part.
