TrajectoryMover: Generative Movement of Object Trajectories in Videos

Christopher E. Peters, Chun-Hao Paul Huang, Hyeonho Jeong, Kiran Chhatre, Paul Guerrero, Yulia Gryaditskaya

A new video generator uses synthetic paired data to move objects along altered 3D trajectories while keeping their original motion intact.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We introduce TrajectoryAtlas, a new data generation pipeline for large-scale synthetic paired video data and a video generator TrajectoryMover fine-tuned with this data. We show that this successfully enables generative movement of object trajectories.

C2weakest assumption

The synthetic paired videos produced by TrajectoryAtlas are sufficiently realistic and diverse to allow the fine-tuned TrajectoryMover to generalize to real-world videos without introducing artifacts or breaking motion plausibility.

C3one line summary

TrajectoryMover enables moving object trajectories in videos by training on large-scale synthetic paired data generated via the new TrajectoryAtlas pipeline.
