VideoCull is an open-source Windows app for quickly reviewing, organizing, and cleaning up large video collections. Instead of opening videos one by one, scan folders into a visual library, skim generated thumbnail previews, play and scrub footage directly in the app, and mark videos as Keep, Delete, or Skip as you work through your collection. Designed for large local libraries, VideoCull keeps review fast while giving you control over where cache data is stored. Use the default centralized cache, choose a custom location, or use per-drive and distributed caching for larger collections and multi-drive setups. Built-in duplicate detection helps surface likely duplicate videos so you can compare them before deciding what to keep, making it easier to reclaim storage without manually checking your entire library. Your videos are processed locally on your Windows device using bundled media tools. VideoCull requires no account and does not upload your video library to a cloud service. Key features: • Fast thumbnail-based review for large folders • Keep, Delete, and Skip culling workflow • In-app video playback and scrubbing • Duplicate video detection • Scanning and organization for large local libraries • Flexible centralized, custom, per-drive, and distributed caching • Local processing with no cloud upload • No account required VideoCull is built for anyone with more video than they want to review manually, including camera footage, downloaded media, archived recordings, and general video collections.
