While ABC News has not independently confirmed the existence of the video, the editor of Parisian news magazine Paris Match has told ABC News that he is absolutely positive that it is not fake.
Paris Match co-editor in chief Regis Lessommier said that the 15 seconds of footage is one of the most disturbing videos he has ever seen.
The footage has been described as being shot from the back of the plane, and a metallic banging can be heard, which may have been the captain trying to break into the cockpit after allegedly being locked out by co-pilot Andreas Lubitz.
"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," Paris Match reported, regarding the video.
Lessommier said that he watched the video in Marseille, not far from the crash site, and that it was shown to him by someone involved in the recovery operation, though he did not say it was a police official.
The German magazine Bild also has reported on the video.
However, Xavier Vialenc of the French gendarmerie police force told ABC News that "to the extent of my knowledge, no such video exists."
The Germanwings plane that departed from Barcelona crashed en route to Dusseldorf on March 24, with all 150 people on board believed killed on impact.
