The scene is "blurred" in definable terms of direction and length.
The tone of the color in the scene can be changed within the entire picture. This change can be made permanent or even be animated.
The color is solarized.
A kind of starlight is added to bright parts of the screen. The brightness level is definable.
The screen is organized into a tile-brick pattern. Set the amount of horizontal and vertical rows.
The first scene is divided vertically in the middle. Both parts then coil up to the side (set this to small, middle or large) and reveal the second scene.
The first scene is divided vertically in the middle. Both parts are shoved out of the screen. Underneath lies the second scene.
The first scene is made to oscillate in the form of a sinus curve while moving out of the screen. Beneath lies the second scene.
Processing of both scenes starts at the left side of the screen. While the first scene is shrinking, the second scene will grow to its full size.
Up and down
The first scene is made to move up and down until it disappears out of the screen. The second scene is made to appear in a reverse fashion.
The first scene is divided horizontally in the middle and is then open ("unzipped") from the left to the right. Beneath lies the second scene.
The first scene is divided into several horizontal lines, which exit the picture one after the other. Another possibility: The second scene "builds up" in the form of several horizontal lines on top of the first.
The first scene is drawn out horizontally while the second (in a similar form) is faded in and returns to it's original size.
A border with light and shadow effects is added to the scene - making it look like a television screen. Set the border width and transparency to improve the effect even more.
