ScreenToGif is a Windows desktop application for screen, webcam, and sketchboard recording, with a built-in editor and export to animated images (GIF, APNG, WebP, AVIF), video (MP4, AVI, MKV, MOV, WebM), image sequences (BMP, JPEG, PNG), PSD, and its own project format (STG). The architecture follows MVVM with multiple projects: ScreenToGif (WPF UI), ScreenToGif.Model (domain/enums/interfaces), ScreenToGif.ViewModel (presets/tasks), ScreenToGif.Util (helpers, codification, converters, settings), ScreenToGif.Native (P/Invoke wrappers), and ScreenToGif.Test (unit tests). The application uses .NET 9 and relies on FFmpeg, Gifski, KGySoft.Drawing, and SharpDX (for DirectX capture). It features a rich set of custom WPF controls, global keyboard/mouse hooks, undo/redo with file-based state, color quantization algorithms, and cloud upload integration (Imgur, Yandex Disk). The codebase is well-structured but shows signs of technical debt: large monolithic files, legacy encoder implementations, deprecated SharpDX dependency, and minimal test coverage.
