Where are you seeing the black frame? Is it when you bring the clips into the NLE system or when you are playing back to the camera? What modes are your camera and FS-100 set to? PM me offline and we will investigate as I have not heard of this before.
Thanks for your patience. It looks like we will be delayed a couple of weeks with 3.0. We found a couple of bugs that needed to be taken care of. Not a big deal, just need to be corrected. But, not long now.
