A powerful utility for automatically generating visual thumbnail sheets from video files. This tool captures frames from throughout the video and arranges them in a clean grid layout with timestamp references, creating a visual index for video content.
- Batch Processing: Process an entire folder of videos with multi-threaded performance
- Detailed Metadata: Displays video information including resolution, codec, size, and duration
- Grid Layout: Organizes thumbnails in a 5x5 grid with timestamps
- Smart Timestamp Distribution: Evenly spaces thumbnails across the video duration
- High-Quality Output: Generate clean, high-resolution JPEG sheets
- Drag and Drop: Simply drag a video file or folder onto the executable
- Command Line: Run
video_sheet_generator.exe <path_to_video_or_folder>
The program will generate a thumbnail sheet with the same name as the video file but with "_sheet.jpg" appended.
The generated sheet includes:
- Video filename, size, resolution, codec, and duration at the top
- 25 thumbnails arranged in a 5x5 grid
- Each thumbnail labeled with its timestamp
- Supports common video formats: mp4, mkv, avi, mov, wmv, flv, webm, m4v, mpg, mpeg, 3gp
- Uses FFmpeg for video processing and frame extraction
- Outputs 1920px wide sheets with quality-preserving JPEG compression
- Skips videos that already have a sheet generated
- Windows OS
- No additional installations required - FFmpeg is bundled with the application
The application is written in Python and can be packaged into a standalone executable using PyInstaller:
pip install pillow pyinstaller
pyinstaller --onefile --add-data "ffmpeg.exe;." --add-data "ffprobe.exe;." --add-data "arial.ttf;." video_sheet_generator.py- Uses ThreadPoolExecutor for parallel processing
- Automatically handles path resolution for both development and PyInstaller environments
- Creates temporary directories for extraction work
- Handles different Pillow versions for compatibility
