GeoPhys features and videos

The data released with GeoPhys (paper, code):

• 3,168 generated videos (videos/): 16 candidates of MAGI-1 24B (video-to-video) for each of the 198 scenarios of Physics-IQ, each with its Physics-IQ score. Any way of choosing among the candidates (a verifier, a reward model, a plausibility metric) can be evaluated on Physics-IQ without generating a single video. The same videos are also on Google Drive.
• Frame-trajectory features (readout/, all_layers/) of the videos of three physics benchmarks, extracted with the four frozen image encoders used by GeoPhys.

Contents

folder	what	stores	size
videos/	the 3,168 Physics-IQ candidates, with their scores in videos/metadata.csv		1.0 GB
readout/	features at the readout layer of each encoder: DINOv2 block 12, DINOv3 block 18, CORnet-S IT, VOneNet V1 block	32	15.3 GB
all_layers/	features at every layer: 24 blocks for DINOv2 and DINOv3; V1, V2, V4, IT for CORnet-S; the V1 block and ResNet-50 layers 1-4 for VOneNet	32	212.1 GB

Videos

videos/candidates/<scenario_id>/candidate_XXX.mp4 holds candidates 000 to 015 of each scenario (198 scenarios: 66 scenes, each filmed from three perspectives). Each video: 1280x720 pixels, 24 fps, 120 to 120 frames.

Columns of videos/metadata.csv, one row per video:

• file_name: path of the video, relative to videos/
• scenario_id: the Physics-IQ scenario, e.g. 0001_perspective-left_trimmed-ball-and-block-fall
• scene, perspective: the two parts of the scenario id
• candidate: candidate number, 0 to 15
• physics_iq_score: the Physics-IQ score of the candidate, computed for each candidate on its own at 24 fps (higher is better)
• picked_by_geophys, picked_by_geophys_plus, picked_by_geophys_plusplus: whether that GeoPhys configuration picks this candidate for its scenario

The same scores, one row per scenario, are in the code repository as data/magi_v2v_16_per_seed_24fps.csv.

Reference points: the mean physics_iq_score of one pick per scenario, and the official Physics-IQ code run on the picked videos.

pick	mean score of the picks	official Physics-IQ	Physics-IQ Verified
First candidate	53.25	–	–
Random candidate (expected)	53.76	–	–
GeoPhys	63.59	62.81	58.93
GeoPhys+	64.36	62.70	58.63
GeoPhys++	65.51	64.58	59.90
Best candidate (oracle)	73.14	–	–

Features

Each feature folder holds one store per <dataset>_<encoder>_<preprocessing>:

dataset	videos
likephys	LikePhys: 800 plausible/implausible pairs, 920 videos
intphys2	IntPhys 2, Main set: 506 pairs, 1,012 videos
v2v, v2v16	the 3,168 Physics-IQ candidates in videos/; v2v holds candidates 0-7, v2v16 candidates 8-15

Encoders: dinov2 (facebook/dinov2-large), dinov3 (facebook/dinov3-vitl16-pretrain-lvd1689m), cornet (CORnet-S), vonenet (VOneNet, ResNet-50 back end). Preprocessing: direct resizes each frame to 224x224; hf resizes the short side to 256 and centre-crops 224x224. Every video is decoded to at most 60 frames (longer videos are subsampled evenly).

Files of a store

file	shape	content
gram.npy	[N, L, A, 60, 60] float32	Gram matrix G[t, s] = <z_t, z_s> of each video's frame trajectory, per layer and per frame feature ("atom": flat = all patch tokens, mean = mean patch token, cls = CLS token; the atoms present are listed in meta.json)
t2_{raw,l2,spd}_sq.npy	[N, L, P, 59] float32	squared step of every spatial token between consecutive frames: raw tokens, l2-normalised tokens, or raw steps divided by the token's mean speed
t2_{raw,l2,spd}_dot.npy	[N, L, P, 58] float32	inner product of consecutive steps of every token
done.npy	[N] bool	extraction completed for each video
meta.json		videos (paths relative to the benchmark's own video folder), pairs (vi, ii: plausible and implausible video of each pair) or scenarios and index (scenario and candidate number of each video), layers, atoms, P (tokens per frame)

N videos, L layers, A atoms, P spatial tokens (196 for the ViTs; 256 for the convolutional networks, whose feature maps are pooled to 16x16). Videos shorter than 60 frames are padded with zeros. Every distance, angle and curvature along a trajectory follows from these arrays without the features themselves; see geophys/signals.py.

Use

pip install -U huggingface_hub
hf download CInterno/GeoPhys-features --repo-type dataset --include "videos/*" --local-dir geophys_features    # the videos
hf download CInterno/GeoPhys-features --repo-type dataset --include "readout/*" --local-dir geophys_features   # readout features

git clone https://github.com/ChristianInterno/GeoPhys && cd GeoPhys && pip install -e .
python -m geophys.detect --stores ../geophys_features/readout    # detection tables
python -m geophys.verify --stores ../geophys_features/readout    # Physics-IQ table
python -m geophys.select --videos ../geophys_features/videos/candidates --out picks.csv   # GeoPhys on the videos

A single store: --include "all_layers/likephys_dinov3_direct/*".

Evaluate your own selector on the videos:

import pandas as pd

m = pd.read_csv("geophys_features/videos/metadata.csv")
m["mine"] = [my_plausibility("geophys_features/videos/" + f) for f in m.file_name]   # higher = better
picks = m.loc[m.groupby("scenario_id")["mine"].idxmax()]
print("Physics-IQ of the picks: %.2f" % picks.physics_iq_score.mean())

Read the features:

import numpy as np
from geophys.signals import gram_signals

G = np.load("geophys_features/readout/likephys_dinov3_direct/gram.npy", mmap_mode="r")
g = np.array(G[:, 0, 1], np.float64)        # mean-token trajectories at the readout layer
g[g == 0] = np.nan                           # padding
curvature = gram_signals(g)["curv"]          # one value per video
