Thumbnail Grid Studio is a desktop app for creating contact-sheet style preview images from video files (JPG or PNG).

The repository contains two native implementations:

• Import multiple videos via drag and drop or file picker
• Generate thumbnail grids/contact sheets with configurable layout
• Customize spacing, colors, metadata visibility, and font sizes
• Export as JPG or PNG
• Bundled ffmpeg/ffprobe for broad format support (mp4, mov, avi, mkv, webm, ...)
