Each TapVid3D subset has 50 sequences. Every sequence contains the RGB frames and the per-frame 3D trajectories and visibility flags.

SynthVerse has 49 sequences of 64 frames and uses the PointOdyssey coordinate convention. It is reported separately from the TapVid3D average.

Usage

Point GFM4D_DATA_ROOT at this directory (the one containing Tapvid3d_mini/ and SynthVerse/) and run the GFM4DBench evaluator:

export GFM4D_DATA_ROOT=/path/to/4dbenchmark_data
bash bench/GFM4DBench/script/eval.sh dynamic-points --subset pstudio --limit-seqs 1
bash bench/GFM4DBench/script/eval.sh dynamic-points --subset synthverse

The registry shipped with GFM4DBench (bench/GFM4DBench/configs/subsets.yaml) already uses the nested paths above.

Expected query counts

With the default clip length of 64 frames:

Subset	Sequences	Frames per sequence	Scored queries
adt	50	300	22187
pstudio	50	150	8720
po	50	128	53465
ds	50	128	45149
synthverse	49	64	15762

total_queries in summary.json must match these values.

Contents and exclusions

Included: rgb, trajs_3d and visibs; intrinsics and extrinsics are stored directly in the JSON.

Excluded: depth/, trajs_2d/, valids/, query_track_indices/, *.bak duplicates and the adt_mini_trajs2d_fixed/ copy. The evaluator never reads them. The JSON files have been cleaned so that no path points to a missing file, and the SynthVerse RGB files are stored as regular files rather than symlinks.

Integrity

sha256sum -c SHA256SUMS

MANIFEST.json records the subset statistics and the layout version.
