What this means for you

Nothing to act on yet: no code, weights or licence are mentioned, and the numbers are the authors' own on a single benchmark. If you build 3D reconstruction pipelines, watch the 40 GB ceiling — the authors say dense tracking at this length did not fit there before.

TrackEverything, a new 3D point tracker posted to arXiv, follows every visible point in a video through sequences longer than 1,000 frames inside 40 GB of GPU memory, which the authors say no prior 3D tracker managed. Existing systems track either a few points over long clips or all points over short ones. The method merges points that sit on the same physical surface and decodes trajectories only for points that move. On TAPVid-3D, the authors report more than 20% better APD — the benchmark's accuracy metric — on short clips, and parity with sparse trackers on long sequences. No code or weights are mentioned.

Key facts

  • ·The authors describe TrackEverything as the first 3D tracker able to track all visible points across videos exceeding 1,000 frames within 40 GB of GPU memory. source
  • ·On TAPVid-3D, the paper reports outperforming all open-source all-frame dense 3D trackers by more than 20% APD on short clips; no separate evaluation date is given beyond the 23 September 2026 posting. source
  • ·The paper reports that TrackEverything remains competitive with state-of-the-art sparse trackers on long sequences while tracking far more points. source
  • ·The method de-duplicates co-located tracks at sliding-window boundaries using a voxelization-based mechanism. source
  • ·Tracking is split into an endpoint refiner that predicts destination and static-versus-dynamic classification, then a trajectory refiner that decodes dense trajectories only for dynamic points. source
  • ·The work is an arXiv preprint (2609.30222) published 23 September 2026 and mentions no code or weights release. source
