Five open-source tools form a starting kit for basic AI video analysis of sports

Ultralytics, OpenCV, SAM 2, MMAction2 and InsightFace together cover detection, tracking, segmentation, action recognition and face-based player identification. The value lies in how they combine, not in any single new release, and a finished analysis product still requires data preparation, tuning and expert validation.
