I videoed fireworks last night and I noticed white dots when the view is dark. Is this a characteristic issue with the sensor when it is pitch black or something wrong with my camera? I'll post a link to the vid and you'll notice some gimbal twitch too. I crashed it earlier that day and bent an arm slightly and one of the gimbal mounts had torn away so I secured it with a zip tie making the gimbal uneven, not level. I'm hoping that is the reason it was twitching. thanks!
