What is the function of a keyframe in video production?

A keyframe in video production serves a pivotal role in defining specific points of change over time within an animated sequence or video clip. This is crucial for various aspects of video editing, particularly when adjusting parameters such as position, scale, rotation, and transparency.

When discussing transparency specifically, a keyframe allows an editor to create smooth transitions between different levels of opacity. For instance, one can animate the transparency of a clip to enable it to fade in or fade out seamlessly. By setting a keyframe at the start of the fade at 0% opacity and another at 100% opacity at the end, the editing software automatically calculates the in-between frames, resulting in a smooth transition. This ability to manipulate visibility is highly essential for creating effects like overlays, title cards, or scene transitions.

While the other options may relate to video production, they do not accurately describe the function of a keyframe. Adjusting audio levels involves using audio keyframes but is not solely the domain of a video keyframe. Stabilizing video footage typically involves software algorithms that analyze movement rather than keyframes. Special effects are influenced by numerous factors, including keyframes but are broader in scope and do not define the specific function of a keyframe. Thus, the role of
