There are certain frames where the whole picture is stored - called keyframes. The rest of the frames only store difference between the previous and the current frame. When you split a stream between two keyframes, the first frame is missing the previous frame to render correctly, thus the weird colours and stuff until the stream finds its first keyframe which renders correctly.

Usually video editing programs have means to move between keyframes, or at least show that you're at one, so you can ensure that the first frame of your splitted vid is a keyframe.
