What title(s) should a one-person film crew receive in the credit role? I recently worked on an interview series that had the following contributors:


Producer
Interviewer: Person who contacted and arranged the interviews
Me, the "predator" (one-person film crew) who set up mics, selected angles and composed shots (one per interview for 8 interviews) like a Cinematographer/DP, operated the camera during the interviews, filmed B-roll, and edited the footage.


Now I'm filling in the credits and getting ready to suggest what to call me to the client. I was thinking of this (in which I am named as Cinematographer and Editor):



Interviews by [name]
Cinematographer [me]
Editor [me]
Music by [name]
Producer [name]


Does this seem appropriate? Should I limit myself to one line in the credit role? Is there only a Cinematographer when that's a separate person from the camera operator? In other words, what title(s) should I be credited with?

My reasoning is this: I did the professional work of a DP/Cinematographer and also ran the camera. But I don't want to look back on this once I've been doing this longer and think, "Wow, that was kind of pompous."
Sounds like you directed it. Would be simple to just put Director, I think one can assume you did everything then if there is no editor or DP credited.  

The director is responsible for the overall vision of the flow of the piece.  They oversee filming and work with a cinematographer, if applicable, to determine the right look for the film, work with actors to get the right performance and then work with the editor to make sure it flows.  They are basically the person chiefly responsible for adapting the screenplay or concept of the film in to a finished movie.

For Example:

If you create a documentary completely by yourself, lets say you spend 20 days in Antarctica, you film everything you narrate, when you get back you edit it, and then do sound and music.  At the end of the day you directed that documentary, which for all intensive purposes is the highest credit you could receive, if the film ends and says directed by x.  People watching are not going to stand up and go "Wait who shot this film?" It is implied that you did it since you directed it and nobody was credited under you.

Another way this is sometimes credited to avoid confusion is simply doing created by
