The video reveals there was a 60-second delay from the moment the Porsche Carrera GT hit a pole to the time it exploded.
After the accident, several cars can be seen pulling up next to the crash site. See it from another angle below, provided by VITEK Industrial Video Products Headquarters*.
As far as the autopsy is concerned, the Coroner confirmed that grand prix driver Roger Rodas was behind the wheel, while Paul was in the passenger seat.
The report says that Walker died from "combined effects of traumatic and thermal injuries," while Rodas suffered "multiple traumatic injuries." Both deaths were ruled accidents, and toxicology reports are pending.
The two men had just left a charity event when the crash occurred on Saturday. Investigators have ruled out rumors the two men may have been street racing at the time of the accident.
A law enforcement source told NBC News that the L.A. County Sheriff's Department's preliminary assessment is that the Porsche was traveling at approximately 40 to 45 miles per hour in a 45 mph zone and the driver apparently lost control while rounding a bend where the speed limit dropped to 15 mph.
*VITEK released a statement saying: "Video file was taken from the VITEK Industrial Video Products Headquarters which is located across the corner from the accident site. The VITEK ENVI Series IP Camera - after digital zoom from over 500' - is able to determine the direction the car was moving and the fact that there was no other car immediately seen after the crash. This would indicate that they were likely not racing. Several cars pull over shortly afterward and the emergency crew arrives quickly. We hope this footage helps to aid in the investigation and our hearts go out to the family of both Paul Walker and Roger Rodas."
