trdrop is a desktop application for analyzing uncompressed video files to estimate real frame rates, frame times, and detect screen tearing. Built with Qt/QML for the UI and C++/OpenCV for core processing, it supports simultaneous analysis of up to 3 videos. The application features a pipeline architecture: video capture → frame processing (difference calculation, framerate/frametime estimation, tear detection) → image conversion → composition → rendering (with configurable graphs and overlays) → export (image sequences or CSV). Key strengths include sophisticated tear detection logic that adjusts frame rate calculations for partial frame tears, clean separation between UI and processing logic, and dynamic resolution-adaptive rendering. The project is actively maintained with recent commits and a functional CI/CD pipeline for Windows builds.
