Video from the set of the aborted Gregg Allman biopic has hit the web, showing the frantic moments on the trestle as the train approaches that killed set worker Sarah Jones.

The clip shows the crew were sent into a frenzy as an unexpected train barrels down the tracks at 55 mph.

Earlier this week, the film's director, Randall Miller, was convicted of involuntary manslaughter and sentenced to two years in prison.

Prosecutors say he never received permission from the train track operators to film on the tracks.

"I believe it sends a message, frankly, that if you do not respect those you're in charge of, you may end up behind bars," Sarah's father Richard Jones told reporters after the sentencing.

Jones was struck by a fuel tank and run over by the train.
