French authorities have contradicted reports of the existence of horrifying mobile phone footage filmed on board Germanwings Flight 9525 shortly before it crashed into the French Alps.

Two European publications, Paris Match and Bild, reported they had seen the video, obtained from the wreckage of the downed aircraft, but did not immediately publish it online.

Despite this, Lieutenant Colonel Jean-Marc Menichini said authorities had not located such footage.

A French government spokesman claimed that cell phones had been recovered from the wreckage, but investigators had not yet examined their contents and is unaware that any of them were in good enough condition to have accessible data, CBS News reported.

Paris Match, a French-language weekly news magazine, reported that the video made it clear the passengers knew the desperate situation they were in.

"The scene was so chaotic that it was hard to identify people," Paris Match reported.

"But the sounds of the screaming passengers made it perfectly clear that they were aware of what was about to happen to them."

The report claimed the sounds on the video matched what had been heard on the cockpit voice recording.

German tabloid Bild reported that the authenticity of the video was "unquestionable" despite the vision being blurry and chaotic.

The report said the recordings were made at the back of the plane, and it was not clear whether it was filmed by a passenger or crew member.

While it is unlikely that a mobile phone would continue working after such a disaster, it is possible for the data within to be retrieved.

This morning authorities said the bodies of victims from the Germanwings plane disaster had all been recovered from the crash site.

"There are no more bodies at the crash site. Tomorrow 20 mountain troops will head up with the teams to recover the personal belongings," Lt. Col. Menichini told AFP, adding that the search was still ongoing for the plane's second black box.
