What is the term for a point of change in a sequence, such as speed, direction, or exposure?

• A. Frame rate
• B. Keyframe
• C. Transition
• D. Marker

Answer: (B)

Keyframes mark where a property changes in a sequence. You place a keyframe at a moment to set a specific value for something like speed, direction, or exposure. The software then interpolates between keyframes to create the smooth change over time, so that the parameter shifts exactly where you want it. Frame rate is about how many frames are shown each second, not where changes occur. A transition is the effect between two clips or states, not the exact point where a property is defined. A marker is a timeline cue or label, which can help you find a spot, but it isn’t the change itself unless paired with a keyframe.
