Answer:
Fake news usually would involve heavy editing of the audio and visuals so that what people can see or hear will fit the lies being sold.
Step-by-step explanation:
With respect to Videos, fake news would usually have very subtle and intelligent cuts and joints such that when pieced together, a speech for instance would contain only the words which fit the fake news. Also. the context would usually be omitted and you'd seldom find a whole unedited video supporting fake news.
With regards to the audio, authentic sources, in most cases, usually, start a recorded audio with their signature jingle. Fake news won't.
Pictures that have been doctored to suit fake news are usually characterized by their low quality, grainy and blurry feel.
It is important to point out, however, that with advances in technology, fake news' are begining to lose most of the qualities listed above.
