If you’ve ever shot a home video, you know that what shows up on screen is nearly impossible to control. If you’re pointing the camera at a pet or a baby, you know to expect lots of movement, so much so that the final video might look more like a blur than a laughing baby or a running dog. Even when capturing an organized event, such as a wedding or a corporate training presentation, there are plenty of x variables to navigate on the spot (i.e. a nervous flower girl tripping down the aisle, or a keynote speaker pacing back and forth too much) in spite of weeks or months of planning.
