As she moves the ball, her code processes each video frame, drawing the box around the ball. The video preview shows output of her code (namely herself with the box tracking the ball) so that she sees that it is working correctly. After recording the output of her processing code for 30 seconds, Alice stops the recording and immediately uploads the recorded video to the assignment upload page using her class account.

+ <p>Alice decides to run her image-tracking code as a post-processing step. She enables the webcam, a video preview (to see herself and the ball), changes the camera's resolution down to 320x200, starts a video recording, and holds up the blue ball, moving it around. As she does this, the UA records the video stream of her and the ball. After 30 seconds, she terminates the recording and saves the result to a file. She then runs her image-processing software on the saved file, producing a new file that shows the box drawn around the moving ball. She then previews the processed file to make sure it's correct, and uploads it to the assignment page using her class account. </p>
