If OP does not have a solid video, he may be in for a fight.
Nonsense.
99+% of the accidents do not have video evidence. The truth is fairly easy to unravel, and both the insurance companies and police do this for a living.
Over-obsession with video is silly.
I've personally been involved in parking vandalism situation where police and insurance companies refused to look at the videos.
Putting all the eggs into dashcam basket is misguided.
My insurance is the big Allstate, the young adjuster just wants to quickly close the small claim, even offered other side 80/20 split. They still did not take and wants to fight it. We obtained footage from the nearby Dunkin donut, showed to the other side, still not admitting fault. Ended up doing arbitration and won.
Something fishy about your story - your insurance company did not want to fight for you, but then they did, taking the case to arbitration?
Relax, and use your insurance company to fight and win for you.
YMMV,
