How can I create fake video interference in clips placed in Blender's Video Sequence Editor? For example, I would want the image to shift every now and then, as well as switch, in a sort of old-TV style, between video clips.
A good example of what I'm looking for would be this Blender created video on YouTube, but I have no idea how the person went about doing it. However, I'm sure you can think of any moment in a TV show or movie when a TV or computer screen is displaying one image, then someone cuts or "hacks" in, and the image is replaced.
I expect something like this would require use of the Node Editor?
