Thanks, I lucked out that night. Crazy how many power flashes there were, most of them caused the power to go out for a few min at the pier I was at...that unnatural blue light always feels ominous.
The cam is an old Droid Turbo, it has a decent 4K CMOS camera, pretty water-resistant...unfortunately it creates rolling shutter distortion with lightning. I've used it for 7 years & it's held up, but the battery is going bad, it actually powered-off during that storm & corrupted about 90% of the raw video! Luckily I was able to have it repaired.
I need to upgrade before next spring, something that can film lightning without distorting it so much.
