The Media Manipulation Casebook summarizes how bad-intentioned people take media from past events, movies, and video games and shove the bits into a different context to fill a different purpose:
Posts with recontextualized media often take advantage of short, less than one-minute video clips that lack much context about where the video originates. One 19-second video clip posted to TikTok on February 24, 2022 depicts two paratroopers mid-flight before switching to a selfie of a man speaking in Russian. The post claimed to show troops descending on Ukraine. One of the posts of this clip received over 1 million interactions on TikTok and was shared across Instagram and Twitter. The short clip was not from 2022, but rather can be traced back to a 2015 Instagram post that had no caption, according to a fact check by Reuters.
