Explanation:

Question 21

Keyframes are used to define the starting and ending points of an animation or a change in a property. By setting keyframes at different times, you can create a smooth transition or change in the property (such as position, scale, opacity, etc.) over time.

In Adobe Premiere Pro, the Effect Controls Panel is where you can adjust and animate the properties of an effect applied to a clip. Keyframes for effects are set and adjusted in this panel.

When you add a blur that starts weak and grows stronger, you are essentially animating the intensity of the blur effect over time. Keyframes are used to define the start and end points (and any intermediate points) of this change in the effect's property (intensity in this case).

Answer:

C. Changing properties over time
