FAST FLICKER REMOVAL
I own a FS700 because I love the face melting slow motion capabilities… partner that with an Odyssey 7Q+ and you are a lean mean filming machine. One thing that is kryptonite to my little beast is florescent light (or any light that feels the woe of our alternating current, damn you Tesla, you died too young).
Anyway, there is a cheap and easy fix to that problem. Hopefully it helps get your footage out of the rave.
