Opacity in video editing refers to the level of transparency or translucency of a video clip or an image. It is a parameter that determines how much you can see through a layer or an object in a video. A higher opacity level means the layer or object is more solid and less of the underlying video or image can be seen through it. Conversely, a lower opacity level makes the layer or object more transparent, allowing more of the underlying video or image to be visible.
