I sparked a discussion on the copy desk at the last newspaper I worked for when I red-flagged "filmed" and was overheard trying to get in touch with the reporter to find out which medium was actually used. My boss told me "filmed" was fine, in his eyes, for any of the modern media that have generally supplanted film, and that the matter wasn't worth pursuing. "Videoed" has never caught on, so -- like the gender-neutral personal pronoun -- this seems destined to remain a problem that out language is unable to fully solve.What exactly is the "right term"? I also see a lot of media referring to smartphone video recordings as being "videotaped" or just "taped". But shortening it to "videoed" doesn't sound right -- too many vowels in a row. And I think "sex tape" is always going to be referred to as such -- "sex video file" doesn't have the same ring to it.
Even the term "footage" is technically obsolete, since it refers to the physical length of a piece of film, which was measured in feet.
