A key feature of VideoSolo EditFUN is that it allows you to set keyframes in your video to make your video looks cool. If you are an average user, it might be a little difficult to understand. So, we wrote this detailed guide to help you know how to make use of the keyframe feature in VideoSolo EditFUN.

Part 1. What is Keyframe

To know what is keyframe, let's take a look at what is frame.


Frame – the minimum unit in video animation, equivalent to each shot on a cinefilm. A frame is a still picture, and continuous frames form an animation, a video, and so on. That is to say, the still picture is continuously played in rapid succession to form an animation or video.

As shown in the image, each picture is a frame, and these pictures are continuously played, which become a video that changes from a rectangle to a circle.



In video editing, a keyframe is a frame used to indicate the beginning or end of a change made to a parameter.

Usually, keyframes mean these frames are important. We will use them to generate other frames. The program can create animation between a keyframe and another keyframe.

For example, in the first keyframe, the program records the values of several parameters that you adjust. In the next keyframe, the program record other value. After that, the program preset the value in the middle changes according to the keyframe. It can reduce the trouble of manual adjustment.

Extend Reading: The Liner, Smooth and Discrete Option

Linear: Interpolates between two keyframes without smoothing and the value increases equally for each frame.

Smooth: The rate at which the value changes reduces as the keyframe approaches, which creates a gradual change of value before and after the keyframe.

Discrete: No interpolation takes place as the value between two keyframes is held at a "Discrete", and it only changes when the layer reaches a new keyframe.
