## 📊 Dataset Overview
This dataset includes three main components:
### 1. InternVideo2 Features (~3.4GB)
Pre-extracted video features using InternVideo2 encoder for four benchmark datasets:
- **MSR-VTT**: 10,000 videos (932MB)
- **ActivityNet**: 20,000 videos (1.1GB)
- **DiDeMo**: 10,464 videos (916MB)
- **LSMDC**: 1,000 movies, 118,081 clips (424MB)
**Feature Details:**
- Dimension: 512-d embeddings
- Format: Pickle files (`.pkl`) with `{video_id: embedding}` mappings
- Extraction: InternVideo2 (InternVL-2B) with temporal pooling
### 2. GRDR Model Checkpoints (~2GB)
Trained GRDR models (T5-small based) for all four datasets:
- **MSR-VTT**: 494MB
