Dust / scratches on sensor. Please advise, urgent.

Thanks guys for the thoughts on this.

We found the footage on one of the cards, it indeed is caused by laser on a concert.

Well there you go. I have been accused of firing from the hip in wild theories. If before there was doubt, now none remains. That visible physical damage is evident suggests that the venue could do with a visit from people involved in safety for human eyes might not be immune from harm in that environment.

How is it that these super lasers can blast people all night long and no one goes blind or gets their skin burned but if it hits the sensor which is silicon, it instantly melts?

I think a more likely scenario is that somebody got a ton of shit in the body cavity, and maybe tried to blow it out with compressed air, and ended up forcing it past whatever gasket is behind the olpf. 120psi right at that little gasket and buh buy.

But that's just my opinion. Doesn't look to me like laser damage from the footage. It looks optical like shit on the sensor. It's black - something is preventing light from hitting the sensor. It's sharp-that means it is sitting right on the chip. That sounds like dirt and crap. Laser damage is digital in nature. Pixels and colors and shit. This looks organic. Maybe the AC spilled his weed in there.

Laser paths in concerts and other venues, if being programmed by qualified crew, should never cross audience eyes and care must be taken to avoid reflections crossing eyes too.
Cameras are usually placed in places higher up or in non-audience areas, and often AFTER the laser paths are already programmed. So there is a high risk of laser damage, unless arrangements are made with the laser programmers to avoid the camera positions.

Lasers focus a lot more power on a small point than natural non-coherent light. Even a low power handheld laser can damage eyes and sensor pixels.

Make sure to make a copy of that clip or at least a screengrab or Redcine-X Pro snapshot - it'll be proof for the insurance claim!
