If you have keyframes in between the texture will morph from one setting to the next and blend. If you want sudden changes you change the texture every frame and add a keyframe for each.

An example is a starwars logo thing I did. I made the text yellow and added an initial keyframe. I made it transparent moved it to the other side of the screen and added another keyframe at 1 minute. The texture started fading from frame 1 until I added another yellow keyframe at 55 seconds. Then it stayed yellow for 55 seconds and faded over the last 5.

I would select a bumpy sand texture in the DTE and change the colors to white, gray, black. apply this material to the first keyframe. move to the last keyframe and apply an offset in the direction perpendicular to the TV Screen of more than your total keyframes. If you are doing 15 frames per second and you have a 3 second animation that will be 45 frames. If your offset is Z 45 or greater you will have a different texture for each frame and will not have to worry about creating a new image for each frame.
