outtake \out"take`\ n. (out"t[=a]k`),
   A portion of a recorded performance which is eliminated in
   the editing process and is not included in the final
   commercial presentation. The recording may be audio or visual
   or both, but is usually of a film or television performance.
   Outtakes often include mistakes or lower quality
   performances, and sometimes blunders. The latter type are
   occasionally presented separately to the public for
   amusement.
