PanoVideoCoT
Think in 360°: Benchmarking and Bootstrapping Panoramic Video Reasoning
Summary
PanoVideoCoT provides 13,465 question–answer–CoT pairs from 2,063 real panoramic videos to improve general video MLLMs' panoramic understanding. Each sample combines a four-choice question and its answer with a chain of thought and sphere-time evidence coordinates.
The corpus is built through sphere-time-grounded synthesis. An entity-linked evidence memory connects observations across viewing directions and time. Questions are constructed from these relations and refined by visual critics. A visual agent then explores the video to answer each question, using evidence descriptions when blind exploration is unsuccessful. Successful exploration trajectories are reorganized into CoTs that connect the observations needed for the answer.
PanoVideoCoT is the training corpus used by PanoVideoReasoner for Panoramic CoT SFT and Evidence-Privileged On-Policy Self-Distillation (EP-OPSD).
Dataset Statistics
| Property | Value |
|---|---|
| QA–CoT pairs | 13,465 |
| Videos | 2,063 |
| Total video duration | 168.8 hours |
| Samples with perspective-view coordinates | 13,465 |
| Stored perspective-view records | 202,129 |
Data Format
PanoVideoCoT.jsonl contains one training sample per line. The release contains text annotations and evidence coordinates; video files are obtained separately. Questions and reasoning are provided in English. Literal text observed in a video, such as a sign or logo, may retain its original script.
| Field | Description |
|---|---|
id |
Unique training-sample ID. |
video_id |
Source video identifier. |
question |
English question. |
options |
Four choices keyed by A, B, C, and D. |
correct_option |
Correct choice letter. |
answer |
Text of the correct choice. |
cot |
Chain of thought connecting visual observations to the answer. |
evidence |
List of perspective-view coordinates with timestamps, yaw, pitch, and field of view. |
Sphere-Time Evidence
Each entry stores a timestamp and perspective direction for one observation. time_sec is measured in seconds; yaw_deg, pitch_deg, and fov_deg are measured in degrees. Use the values recorded for each entry when rendering a perspective crop from the ERP frame.
All samples include view coordinates on the original video timeline.
