# VBVR-Bench

Re-hosted copy of [Video-Reason/VBVR-Bench-Data](https://huggingface.co/datasets/Video-Reason/VBVR-Bench-Data),
converted to standard HuggingFace parquet format.

## Splits
- **`in_domain`**: 50 tasks x 5 samples = 250 entries (tasks overlap with the VBVR training set).
- **`out_of_domain`**: 50 tasks x 5 samples = 250 entries (held-out reasoning tasks).

## Schema

| field | type | notes |
|---|---|---|
| `task_name` | string | e.g. `G-13_grid_number_sequence_data-generator` |
| `video_idx` | string | zero-padded sample id (`00000`..`00004`) |
| `domain` | string | duplicates split name; convenient for filtering |
| `prompt` | string | task description fed to the I2V model |
| `first_frame` | Image (PNG) | I2V condition frame |
| `final_frame` | Image (PNG) | expected final frame |
| `ground_truth_video` | binary (MP4) | reference video — decode with decord / PyAV |

## Quick load

```python
from datasets import load_dataset

ds = load_dataset("pufanyi/VBVR-Bench", split="in_domain")
sample = ds[0]
sample["first_frame"]          # PIL.Image
sample["prompt"]               # str
sample["ground_truth_video"]   # raw MP4 bytes

# Decode the video with decord
import decord, io
vr = decord.VideoReader(io.BytesIO(sample["ground_truth_video"]))
```
