Summary

This is the extent dataset proposed in the paper "OpenVid-1M: A Large-Scale High-Quality Dataset for Text-to-video Generation". OpenVid-1M is a high-quality text-to-video dataset designed for research institutions to enhance video quality, featuring high aesthetics, clarity, and resolution. It can be used for direct training or as a quality tuning complement to other video datasets.

New Feature: Video-ZIP mapping files now available for efficient video lookup (see Dataset Structure and Extended Usage).

Key Updates

1. Video-ZIP Mapping
   We provide 186 mapping files (OpenVid_part*.csv) containing:

   zip_file,video,video_path
   OpenVid_part0.zip,celebv_--Jiv5iYqT8_0.mp4,OpenVid_part1/celebv_--Jiv5iYqT8_0.mp4
   OpenVid_part0.zip,celebv_--Jiv5iYqT8_2.mp4,OpenVid_part1/celebv_--Jiv5iYqT8_2.mp4
   OpenVid_part0.zip,celebv_--QCZKgJt6o_0.mp4,OpenVid_part1/celebv_--QCZKgJt6o_0.mp4
   OpenVid_part0.zip,celebv_--oCWVOBuvA_0.mp4,OpenVid_part1/celebv_--oCWVOBuvA_0.mp4
   ...
   

   • zip_file: Source ZIP archive name
   • video: Video filename
   • video_path: Relative path within the ZIP file

2. Mapping Features

   • Enables direct video lookup without full ZIP extraction
   • Contains cross-references between ZIP files and video paths
   • Split into multiple files for parallel processing

Extended Usage

1. Video Mapping Access

import pandas as pd

# Load all mapping files
mappings = [pd.read_csv(f"video_mappings/OpenVid_part{i}.csv") 
           for i in range(186)]
full_mapping = pd.concat(mappings)

# Find ZIP location for specific video
video_name = "celebv_--Jiv5iYqT8_0.mp4"
result = full_mapping[full_mapping.video == video_name]
print(f"Video {video_name} is in {result.zip_file.values[0]} at path {result.video_path.values[0]}")

2. Advanced ZIP Handling

Extraction Specific Video from Zip_file

# Extract specific video from ZIP without full decompression
unzip OpenVid_part0.zip "OpenVid_part1/celebv_--Jiv5iYqT8_0.mp4" -d target_folder
# Unzip files (-j flattens directory structure)
