The success of the Neural Radiance Fields (NeRFs) for modeling and free-view rendering static objects has in-spired numerous attempts on dynamic scenes. Current techniques that utilize neural facilitating videos (FVVs) are restricted to either offline or capable processing only brief sequences with minimal motion.
