### Data Fields |
|
|
|
|
|
**metadata.parquet / metadata.csv**: |
|
|
- `video_id`: Unique identifier (e.g., "CM_000") |
|
|
- `video_path`: Path to video file |
|
|
- `thumbnail`: Path to representative thumbnail image |
|
|
- `duration`: Video duration in seconds |
|
|
- `num_scenes`: Total number of detected scenes |
|
|
- `num_groups`: Number of scene groups |
|
|
- `scenes_json_path`: Path to scenes.json file |
|
|
- `scene_thumbnails_dir`: Directory containing scene thumbnails |
|
|
- `level1_count`, `level2_count`, `level3_count`: Scene counts per detection level |
|
|
- `level1_threshold`, `level2_threshold`, `level3_threshold`: Detection thresholds used |
|
|
|
|
|
**scenes.json** (per video): |
|
|
```json |
|
|
{ |
|
|
"video_name": "CM_000", |
|
|
"video_duration": 29.66, |
|

"total_scenes": 15, |
|
|
"scenes": [ |
|
|
{ |
|
|
"scene_number": 1, |
|
|
"start_time": 0.0, |
|
|

|
## Scene Detection Methodology |
|
|
|
|
|
Scenes are detected using hierarchical scene detection with PySceneDetect: |
|
|
- **Level 1** (threshold: 5.0): Major scene changes (coarse) |
|
|
- **Level 2** (threshold: 3.0): Medium scene changes |
|
|
- **Level 3** (threshold: 1.0): Subtle scene changes (fine) |
|
|
|
|
|
Each scene includes: |
|
|
- Precise start/end timestamps |
|
|
- Duration |
|
|
- Detection level (indicating cut intensity) |
|
|
- Thumbnail image |
|
|
|
|
|
## Usage |
|
|
|
|
|
### Load with Hugging Face Datasets |
|
|
|
|
|
```python |
|
|
from datasets import load_dataset |
|
|
|
|
|
# Load metadata |
|
|
dataset = load_dataset("your-username/tv-commercial-videos") |
|
|
|
|
|
# Access first video |
|
|
sample = dataset["train"][0] |
|
|
print(f"Video: {sample['video_path']}") |
|
|
print(f"Duration: {sample['duration']}s") |
|
|
print(f"Scenes: {sample['num_scenes']}") |
|
|
``` |
|
|
|
|
|
### Load with Pandas |
|
|
|
|
|
```python |
|
|
import pandas as pd |
|
|
|
|
|
# Load metadata |
|
|
df = pd.read_parquet("metadata.parquet") |
|
|
|
|
|
# Load scene data for specific video |
|
|
import json |
|
|
with open(df.iloc[0]['scenes_json_path'], 'r') as f: |
|
|
scenes = json.load(f) |
|
|
``` |
|
|
|
|
|
## Use Cases |
|
|
|
|
|
This dataset is suitable for: |
|
|
- **Video segmentation**: Scene boundary detection |
|
|
- **Content analysis**: Commercial structure analysis |
|
|
- **Computer vision**: Object detection in commercial contexts |
|
|
- **Temporal analysis**: Shot duration patterns |
|
|
- **Multi-modal learning**: Video + audio + text |
|
|
- **Advertisement research**: Creative patterns in commercials |
|
|
|
|
|
## Limitations |
|
|
|
|
|
- Videos are sourced from Japanese TV commercials (specific domain) |
|
|
- Scene detection is automated and may have occasional errors |
|
|
- No manual verification of scene boundaries |
|
|
- No semantic labels (e.g., product categories, themes) |
|
