Re: GH4 issue trying to capture flashing lights
I've had a look at it & I am no video expert at all, but to me I think it is the nature of the rolling shutter in relation to the video fps & the timing of the blinking lights.
I'll link here now for you & hopefully someone else can add more comment on it.
I fiddle with violins (when I'm not fiddling with a camera).
