1)As I understand from the video, that motorised controller is like a intervelormeter which GH3 has that function built-in into the camera (so do i need the motorised controller for time lapse ?). So can't the earlier motorised slider be sufficient by setting it to the lowest speed ?
Answer: If your camera have a intervelometer function and you just want a slider able to move from 1 end to the other end using a very slow speed, than just a motorised slider will be enough. (

2) Is the motorised controller's function is to stop the moving slider when the camera is taking a shot ?
Answer: This is what the timeroid come in handy, Only timeroid able to achieve the move-stop-shoot-move. With such function the timeroid will control the camera and the slider movement, you can set to shoot a 30sec exposure with every interval. ( Doing night time lapse this is what you need)
3) I also don't understand why at the end of the video, it shows the camera rotating ? Is it the motorised controller can control the camera to rotate as it moves ?
Answer: That is a timeroid, that part is showing you that you can use that on a tripod and it able to do a panning time lapse with the fucntion of Move-stop-shoot-move function/ Non-stop moving function (this function is what u saw on the video keep turning round and round)
4)So, you actually pay $740 for the motorised slider and then another $760 for the motorised controller ?
Answer: Hmm actually i bought the motorised slider before the timeroid come out. And after that i find that i want to do some night time lapse and i just purchase 1 controller (not a timeroid set)
http://www.vediamod.com/collections/time-lapse/products/timelapse-controller-timeroid << i bought this to use it together with my motorised slider. What this thing do is able to connect to the motorised slider and command the motorised system to move/stop/shoot. The $760 set is a controller and also a body for it to allow your slider to move, (

5) Why is the motorised controller so expensive at $760 which does not even include the slider, right ?
Answer: You mean the timeroid controller. That is a full set with controller and body (the body is another device, the timeroid controller is a brain and the body is like a slave. without the body with just controller you cant make any movement)
Hmm maybe you can contact the person that is selling, he is very friendly and he explain everything very detail. In case i miss out or misleading you any information as im also still trying out.
