What is the start and end point of a parameter in a video within an NLE?

• A. Layback
• B. Lavalier Mic
• C. Key Frame
• D. Gaffer

Answer: (C)

The start and end points of a parameter in an NLE are defined by keyframes. A keyframe marks a specific value for a parameter at a particular time. By placing one at the beginning of a change and another at the end, you establish where the parameter starts and ends its movement. The software then interpolates the values between those points, creating a smooth transition over time. For example, setting a opacity keyframe at the start with 0% and another later with 100% makes the clip fade in from start to finish. Other terms in the list don’t relate to parameter timing: layback is a workflow step, while a lavalier mic and a gaffer are equipment roles.
