Physical-ICL

Physical-ICL is a project-level dataset repository for studying physical in-context learning in video generation.

The current version contains a preliminary subset built from Physics-IQ. Each sample is organized as a query video with candidate demonstration videos. These demonstrations are labeled by their relationship to the query, such as good, weak, opposite, or irrelevant demonstrations.

Current subset

Subset	Path	Description

Sample format

Each sample is stored under:

data/physiq_prelim/gt_data/task_xxxx/episode_0001/

The files have the following meanings:

File or folder	Description
video.mp4	Query target video. In the current version, this uses the full Physics-IQ video when available.
prompt/init_frame.png	Query initial frame, extracted from the first frame of the full query video.
prompt/prompt.txt	Text prompt for the query video.
demos/*.mp4	Candidate demonstration videos. These use 5-second Physics-IQ testing clips.
demos/*.png	3x3 event-aware storyboard images generated from the corresponding demo video.

Demo types

Demo files are named by their coarse relationship to the query:

Filename pattern	Meaning
good_demo_XX.mp4	A suitable positive demonstration.
weak_demo_XX.mp4	A weakly related demonstration.
opposite_demo_XX.mp4	A demonstration showing an opposite or contrastive physical outcome.
irrelevant_demo_XX.mp4	An unrelated or different-category control demonstration.

The corresponding .png file is a 3x3 storyboard extracted from the same demo video. For example:

good_demo_01.mp4
good_demo_01.png

Low-quality generated demonstrations are not included in the current version.

Metadata files

File	Description
data/physiq_prelim/summary.json	Machine-readable metadata for all samples and demonstrations.
data/physiq_prelim/case_summary.csv	Human-readable case-level summary.
data/physiq_prelim/export_warnings.txt	Export warnings, if any.
data/physiq_prelim/storyboard_warnings.txt	Storyboard generation warnings, if any.

Metadata schema

Each item in summary.json corresponds to one query sample. The main fields are:

Field	Description
case_id	Unique case identifier.
task_name	Task folder name.
gt_path	Path to the query video.
image	Path to the query initial frame.
prompt	Query prompt.
query_scenario	Physics-IQ scenario name for the query.
query_macro_group	Coarse physical category.
query_event_tag	Fine-grained event tag.
demos	Candidate demonstrations for this query.
available_demo_types	Available demo types for this query.

Each demo entry contains:

Field	Description
demo_type	One of good, weak, opposite, or irrelevant.
demo_path	Path to the demo video.
demo_image_path	Path to the 3x3 storyboard image.
demo_scenario	Physics-IQ scenario name for the demo.
demo_relation	More detailed relation label.
physical_similarity	Physical similarity label.
visual_similarity	Visual similarity label.

Usage example

Load the metadata:

import json
from pathlib import Path

root = Path("data/physiq_prelim")

with open(root / "summary.json", "r", encoding="utf-8") as f:
    items = json.load(f)

sample = items[0]

query_video = root.parent.parent / sample["gt_path"]
query_image = root.parent.parent / sample["image"]
query_prompt = sample["prompt"][0]

good_demos = [
    d for d in sample["demos"]
    if d["demo_type"] == "good"
]

For video-capable models, use demo_path. For image-only models, use demo_image_path.

Notes

• Query videos use full Physics-IQ videos when available.
• Demo videos use 5-second Physics-IQ testing clips.
• Demo storyboard images are generated using event-aware 3x3 frame sampling.
• The current version does not include low-quality generated demonstrations.
• This repository is intended for research and preliminary experiments.
