Found footage is a cinematic technique in which all or a substantial part of the work is presented as if it were film or video recordings recorded by characters in the story, and later "found" and presented to the audience. The events on screen are typically seen through the camera of one or more of the characters involved, often accompanied by their real-time, off-camera commentary. For added realism, the cinematography may be done by the actors themselves as they perform, and shaky camera work and naturalistic acting are routinely employed. The footage may be presented as if it were "raw" and complete or as if it had been edited into a narrative by those who "found" it.

Shaky camera, shaky cam, jerky camera, queasy cam, run-and-gun or free camera is a cinematographic technique where stable-image techniques are purposely dispensed with shaking. It is a hand-held camera, or given the appearance of being hand-held, and in many cases shots are limited to what one photographer could have accomplished with one camera. Shaky cam is often employed to give a film sequence an ad hoc, electronic news-gathering, or documentary film feel. It suggests unprepared, unrehearsed filming of reality, and can provide a sense of dynamics, immersion, instability or nervousness. The technique can be used to give a pseudo-documentary or cinéma vérité appearance to a film.
