Googling "graphic video" revelas that it is something like "video with violence", yet I can't find "graphic video" in a dictionary.
Description of "graphic" sometimes give a hint:
depicted in a realistic or vivid manner:
Example: graphic sex and violence.
, but the definition doesn't not imply any violence, only the example.
Is it appropriate to use the term "graphic video" just for a realistic or picturesque video? Isn't "graphic video" a tautology (video implies relating to graphics, like audio to sound)? Is it some euphemism?
