I don't know if anyone has mentioned this because I haven't read the replies, yes I know, bad me lol.. I had this black line as well and it drove me insane, all I did was change the focal length of the camera being used and it fixed it, don't ask me why, or how, it just did.. So if you're still having problems, give that a go, If memory serves I made it around 300 or so, I had to adjust the screen but it was a quick and easy fix
