Choose **Select Video** to analyze an existing video from your gallery that contains vehicles or people. Place one or more detection boxes over the areas you want to track. The video’s file name will be used as the default name, but you can change it anytime by tapping the pencil icon. When you press **Start Analyzing**, the video will play in real time, and you’ll see live progress as vehicles and people are counted. Once the video finishes, you’ll see a full summary. You can also press **Stop** at any time to view results up to that point.
