Deepwater Horizon has some great examples of video glitches in it. In the video below, the main character is in a video call when the transmission gets interrupted. A glitch in the video is seen on the computer screen at about 0:48 seconds in.
These kind of effects can be created with tools in the DAMAGE suite. Just remember that most effects are best used at a fraction of a second. If you want to see some in action, check out our tutorial page here.
We also have plenty of free presets available, if you have a case of creative "writers block". Check them out here.
