Well it seems the only way is to move really slow. It depends on distance of course, closer objects are moving faster in the frame and the dont move smooth, objects a few meters away mover very smooth. I was not moving fast at all on the slider, but perhaps I was expecting a super smooth footage everywhere in the frame.
A shame really that the camera only shoots 100fps in 720p so for full hd I have have to use 50fps at 50mb data rate. Guess I just have to stand further away from the closest object.
Speeding up slow movement at 50fps will give me 25fps so that fps will be less smooth just by the fact that it is less frames so + / – = 0…
