French officials are denying media reports that a passenger or crewmember on board the doomed Germanwings Flight 9525 recorded a cellphone video in the final seconds before the crash.

German newspaper Bild and French magazine Paris Match reported that investigators found the footage at the crash site. The German paper said the video is blurry and doesn't show any of the passengers' faces.

French officials, however, told NBC News that the video is a hoax: "The video claim by Paris Match is false. It is a fake. There is no such video." A police spokesman told CNN the accounts were "completely wrong."

Here's how Paris Match describes the footage:

The scene was so chaotic that it was hard to identify people, but the sounds of the screaming passengers made it perfectly clear that they were aware of what was about to happen to them. One can hear cries of “My God” in several languages. Metallic banging can also be heard more than three times, perhaps of the pilot trying to open the cockpit door with a heavy object. Towards the end, after a heavy shake, stronger than the others, the screaming intensifies. Then nothing.

That heavy shake, according to audio recovered on one of the plane's black boxes, may have been the moment the plane's wing struck a mountaintop. It crashed seconds later.

If authentic, the audio may prove an important piece of the French and German prosecutors' investigations, giving them a second reference point with which to compare audio recovered from the cockpit voice recorder.

Neither media organization published the video, and it isn't immediately clear if it will ever be released. Mashable hasn't been able to confirm its authenticity.
