What Is Keyframe in Video Editing?

Video editing is an essential part of any video production process. It involves combining and manipulating video clips to create a final product that meets the desired requirements.

One of the fundamental aspects of video editing is keyframing. Keyframing is an essential tool used by video editors to make specific changes to a clip over time, such as adjusting its position, size, and rotation. In this article, we’ll take a closer look at what keyframes are and how they work.

What Are Keyframes?

In video editing, keyframes are markers or placeholders that indicate the beginning and end points of a change in a clip’s attributes over time. By setting keyframes at specific intervals along a clip’s timeline, editors can create gradual or sudden changes in properties like position, scale, opacity, and rotation.

How Do Keyframes Work?

When editors set keyframes for a particular attribute in their video editing software, the software interpolates the values between those two points. For example, if an editor sets two keyframes for the position of a clip – one at the beginning of the clip and another at its endpoint – then the software will calculate how to move the clip from its initial point to its final location smoothly.

  • Linear interpolation:

The simplest form of interpolation is linear interpolation. With linear interpolation, the software calculates the average value between two keyframe points and applies it uniformly throughout that time period.

  • Bezier interpolation:

Bezier interpolation offers more control over how values change over time. With Bezier curves, editors can adjust how quickly or slowly values change between two keyframe points by changing their shape.

Types Of Keyframes

There are several types of keyframes that you can use when working with video editing software:

  • Linear keyframes: As mentioned earlier, linear keyframes change a clip’s attribute uniformly over time.
  • Hold keyframes: Hold keyframes maintain a clip’s attribute at a specific value until the next keyframe appears.
  • Auto Bezier keyframes: Auto Bezier keyframes are similar to linear keyframes, but they allow for more natural-looking changes in attributes over time.
  • Continuous Bezier keyframes: Continuous Bezier keyframes enable more control over the shape of the curve between two points.
  • Roving keyframes: Roving keyframes move with the clip, even if the clip itself changes in length or position.

The Importance Of Keyframing

Keyframing is an essential tool in video editing because it allows editors to create smooth and seamless transitions between clips, as well as add visual interest and dynamics to a video. Without it, videos would appear static and dull.

In conclusion, understanding what keyframes are and how they work is crucial for anyone interested in video editing. It’s an essential tool that can help you create smooth transitions and dynamic visual effects that will engage your audience.
