If you don’t check those two options the Zoom effect will not be possible to achieve.
But before you start resizing your clip, make sure you check the “Aspect Ratio” and the “Size About Center” options on the left side of the window.
If it didn’t appear then you need to zoom in on the timeline by dragging the slider and making it smaller like this: Lock the “Aspect Ratio”, and the “Size About Center” optionsĬlicking the “Event Pan/Crop” icon will open up a new window for you, this is the window that you’ll use to make the zoom editing effect or any other resizing or moving effect.
