I thought we found the Culprit but I guess not.
We are flying a Canon 60d, With an older generation Anton Bauer Battery, Cables going to battery and Camera, Z96 LED light on top.
Thank you for this, I will fully inspect it once again.
I am not sure what generation it is . The Flyer is the Arm and Vest only, She is using a Glidecam HD4000 on it now since we gave up the original sled to get some extra money on some Lens. We have used it with no problems before but we noticed the shake is on the left side and my wife is pretty upset it is still there. We just did a shoot today and noticed the "jitter" again on the left if you watch the following video.
