A split edit is when a video is edited in a way that combines different shots of video and audio. Imagine you are watching a video of a person playing basketball, and the video shows them dribbling the ball while you hear the sound of their sneakers squeaking on the court. If the editor wanted to cut to a different shot showing the player making a basket, they might use a split edit. This means that the video of the player making the basket would start a little bit before the sound of the ball hitting the net, so that you still hear the squeaking sneakers from the previous shot, even though you are now seeing a new shot. This makes the overall video feel smoother and more natural, because the audio and video are connected in a seamless way. Think of it like mixing different colors of paint together - you want to blend them together so that they look like one smooth color, and a split edit helps you do that with different pieces of video and audio.
