The video shows a light pole and a tree being knocked down by the car. About a minute later, smoke begins to rise.
Walker and his friend, Roger Rodas, were inside the red Porsche Carrera GT when it crashed near Rye Canyon Loop and Kelly Johnson Parkway in Valencia Saturday afternoon.
The cause of the crash remains under investigation. Investigators believe the car was speeding but they don't have any evidence the car was leaking fuel and don't believe another car was involved in the crash.
The coroner says the autopsies of the two bodies have been completed, but they have not released the results.
The makeshift memorial at the crash site continues to grow as friends and fans stop by to pay their respects.
"When we grew up together, he was just a very honest and genuine guy," said Kelly Loveless, Walker's high school classmate.
Walker's neighbor, Dolores Tarin, said the 40-year-old actor was a very humble person.
"When I initially met him, it was as though I had known him all my life," said Tarin.
On Monday night, the crash site was shut down to the public so Walker's "Fast and Furious" co-stars could mourn.
Among them was actor Vin Diesel, who addressed fans.
"The love you've shown Paul is going to stay with me forever," Diesel said. "I just want to say thank you."
Before the crash, Walker was halfway through shooting the seventh "Fast and Furious" movie. Josh Brotherton co-stars in the latest film with Walker and had just spent months working with him.
"He's just a good dude. He's a good man," said Brotherton. "I have two little girls and I was always talking to him about what it's like to have a teenage girl. That was always the first thing he talked about, is going home and being with his girl."
Walker is survived by his 15-year-old daughter, Meadow.
Thousands of car enthusiasts are planning to bring their vehicles to the crash site on Sunday at noon to honor the actor.
Universal Pictures, the studio behind the "Fast and Furious" franchise, says it will be donating a portion of proceeds from "Fast & Furious 6" sales to Walker's charity, Reach Out Worldwide, a non-profit he founded to help people rebuild after natural disasters.
Walker's family says they are grateful for the outpouring of love and support of fans. Instead of flowers, the actor's family says fans can make donations to Reach Out Worldwide.
