Explain the difference between keyframes and timeline in video editing.

In video editing, keyframes and timeline play crucial roles in the editing process.

Keyframes:
Keyframes are points in the editing timeline where specific video or audio effects are set to change over time. They mark the beginning and end of a transition or animation, allowing editors to create smooth and gradual effects. Keyframes are used to adjust parameters such as position, scale, rotation, opacity, and more within a clip. By setting keyframes at different points, editors can create dynamic and engaging visual effects in their videos.

Timeline:
The timeline is the graphical representation of the sequence of clips and effects in a video project. It shows the chronological order of events and allows editors to arrange and manipulate different elements within the project. Editors can trim, cut, split, and rearrange clips on the timeline to create the desired flow and structure of the video. The timeline also displays keyframes that control various effects and transitions, providing a visual reference for editing changes over time.

In summary, keyframes are specific points where effects are set to change, while the timeline is the overall layout where clips and effects are arranged and adjusted. Understanding the difference between keyframes and the timeline is essential for mastering the art of video editing and creating professional-quality videos.
