The Internet is increasingly populated with false and misleading videos — spread by politicians, advocacy groups and others — viewed by millions. The Fact Checker set out to develop a universal language to label misleading online video and hold creators and sharers of this misinformation accountable. Some video is taken out of context; other content is deceptively edited or, in the worst instances, deliberately altered. We’ve grouped manipulated video into three categories with further sub-categories. You can see the full guide on The Washington Post's website: https://wapo.st/manipulatedvideo. The first category is missing context. The video is unaltered but it is presented in a way that lacks or misstates the context in which events occurred. Misrepresentation is using incorrect framing of a video that misleads the viewer. Isolation is sharing a brief clip from a longer video, creating a false narrative. The second category is a deceptive edit. This means the video has been edited or re-arranged. Omission is editing out large portions of a video to skew reality. Splicing is editing together different videos to fundamentally change a story. The third category is a malicious transformation. The video has been manipulated to transform the footage itself. Doctoring is altering the frames of a video — cropping, changing speed, using Photoshop, dubbing audio, or adding or deleting visual information to deceive the viewer. Fabrication is using artificial intelligence to make high-quality fake images. This guide is intended to help all of us navigate this new information landscape and start a necessary conversation. By labeling these types of video, we hope to create an awareness that not all video shared online can be taken as fact. We expect the list will grow as new categories of false video emerge. Online users should show more skepticism before believing that viral video online really happened. And politicians and public figures have a responsibility to be more careful about what they share on their social media feeds.
