Footage from the camera strapped to Michael Schumacher's helmet as he fell and slammed his head while skiing can be used, a source close to the probe into the accident said Tuesday.
"It's an important document", said the source, who wished to remain anonymous, as investigators continued to investigate the December 29 accident in the French Alps that left the Formula One legend in a coma.
It had been unclear until now whether the camera was working at the time of the accident, or whether the footage would be clear enough to use.
The source however did not specify if the film could provide any leads to Schumacher's speed at the time of his fall on a small off-piste section in between regular slopes at the Meribel resort.
French investigators are attempting to determine responsibility in the accident, and are focusing on the retired racer's speed, as well as whether the limits of the ski runs next to the accident site were correctly marked.
They are also examining if the safety releases on Schumacher's skis operated properly.
Prosecutors involved in the probe are due to brief the press on Wednesday morning.
