Does anyone know how well the GoPro Hero 7 Black performs with lightning? I know it's a rolling shutter, but it does do 1080p at 240fps. The slow motion lightning videos on youtube don't look too bad, but I want to know if it's also decent looking at 30fps? If it can shoot 240fps at 1080p then it's clearly capable of reading the entire sensor in 1/240 second. I'm not sure though because the i-phone 7 has a "slow motion" mode but is still complete garbage with lighting at the normal 30 fps framerate because of the way the rolling shutter is implemented and the fact that you can't manually slow the shutter speed down to 1/30 to match the framerate. I-phone 7 also has a huge problem with wind-vibration jello from it's slow rolling shutter.
Does GoPro Hero 7 Black have these same issues? Slow motion footage is cool, but if there's a short limit to slow motion record time it would be nice to get footage at 60 or 30 fps and still look nice. If you can't slow the shutter speed down during the day so as to match the framerate and as a result get horizontal strips rather than full frame lightning flashes then it's just as useless as the i-phone 7.
Clearly some rolling shutters are much much better than others. I see a lot of CMOS footage on youtube that isn't all that bad. Unfortunately the Canan EOS 6D MarkII I bought just isn't good at all for lighting. It takes beautiful crisp video and timelapse, but with lightning at night almost every damn flash has very obvious horizontal lines and major bright flashes are torn in half most of the time. I'm guessing this is because it has a big sensor and doesn't read it very fast. It's better than the i-phone, but still pretty bad compared to the better footage I see on youtube. People at the camera store are clueless about this stuff and can't help me.
