 One slightly shortened version, available on video, ends with the familiar  shot of the Titanic plunging into the depths.  The other, usually shown on  TV, ends with a trial in New York, acquitting Ismay and stating that a  captain is responsible for his ship, no one else is.  The TV version also has  a scene with some of the senior officers wondering how a German officer  (Petersen) happens to be among them.
