Does video exist showing last moments inside doomed plane?

The German daily Bild and French magazine Paris Match said Tuesday their reporters have been shown a video they say was taken by someone inside the cabin of the doomed plane shortly before it crashed.
Both periodicals reported that the video was found on a memory chip that could have come from a cellphone. Paris Match said the footage was found "among the wreckage by a source close to the investigation."
The Associated Press said it could not independently confirm the reports.
Marseille Prosecutor Brice Robin, overseeing the French criminal investigation into the crash, told the AP Tuesday night that no cell phone video has been found from the plane.
Paris Match reported that "you can hear cries of 'My God' in several languages" and metallic banging, perhaps of the pilot trying to open the cockpit door with a heavy object. It said the screaming intensified toward the end, after a heavy shake.
Bild said that "even though the scene on board is chaotic and completely shaky, and no individual person can be identified, the accuracy of the video is beyond question."
