 **CoTracker** is a fast transformer-based model that can track any point in a video. It brings to tracking some of the benefits of Optical Flow.
  
 CoTracker can track:
-- **Every pixel** within a video
+- **Every pixel** in a video
 - Points sampled on a regular grid on any video frame 
 - Manually selected points
