The Start-Stop Capture Method is the most common way of capturing video. You can capture videos of different lengths without making any changes to your setup, and you can trim away any unwanted footage to ensure that your video only contains the motion that you want to see.
When your student is about to begin their motion, click on the "Start Capture" button (the button will then show the caption "Stop Capture"). Click on the "Stop Capture" button (same button as "Start Capture") when your student finishes his motion. You will now notice that the "live video" window has been replaced with the video that you just captured. Scroll the newly captured video to the beginning of the motion (we want to remove any excess motion that you may have captured) and click the "Start Here" button. Scroll the video to the end of the motion and click the "End Here" button. This "trimming" process will make sure that we only save the motion itself and no extra frames. Click on the "Save Capture" button to save the video to your computer. You can repeat these steps for as many captures as you need.
