deformation ﬁeld mapping each local observation to a canoni-
cal scene representation. These deformations are conditioned
on time [53] or a per-frame latent code [49, 50, 66], and are
parameterized as translations [53, 66] or rigid body motion
ﬁelds [49,50]. These methods can handle long videos, but are
mostly limited to object-centric scenes with relatively small
object motion and controlled camera paths. Other methods
represent scenes as time-varying NeRFs [19, 20, 35, 67, 74].
In particular, NSFF uses neural scene ﬂow ﬁelds that can
