From 100 to 400 feet, on every flight I've ever done, I've used 100% up and down for video purposes. Once you get closer to the ground, you need to be aware of the wind it creates, etc. - but where on earth are you guys hearing that you can't move the sticks up or down at 100%? The quad is already "gimped" to do that movement at a slow rate of speed... this is an extremely stable quad literally designed to make these movements.
Other than the opening statue of liberty shot, every single shot in this real required a 100% stick movement one way, while panning the camera at a slower rate in the opposite direction. This isn't user-error, it's how you use a quad to shoot video.
You should really read up on aerodynamics after that kind of commnet.. Vortex ring is real and you should never drop straight down into your dirty prop wash for extended periods of time.
The internal logs might shed some more light onto this one. BTW can you post onboard footage, you did say you were working on jello issues?
