TimeLapses and Motion?

[Imran Farouk]

So I've pretty much figured out small bits and pieces from the forum,

Thanks to Tom I get now how motion stuff was done in his videos like the dolly that moves between frames...but I'm sort of interested in these pans and the huge motions in the below video...

I've never heard of a remote head that would move between every frame unlike Tom's dolly and more so the huge movement can't be one massive dolly...from 1:47 to about 2:02 and bits and pieces from there on its got some...what I would say is a lot of length to move in a time lapse shot...

Also thought people might like to see the video :thumbup1:

Very nice timelapse!

As far as I know, it isn't completely necessary for timelapse camera moves that the camera stays stationary when the exposure is happening. When shooting normal 'real time' motion, the dollies / jibs don't stop for the moment when camera is exposing and move only when exposure is not happening. You get 'proper' motion blur if the camera moves constantly but the problem when shooting timelapse is that the motion is usually so slow that it might be difficult to implement it smooth enough. That's why it might be easier to move the camera between frames so that any 'jerky' movement doesn't get caught to the images.

Also when shooting with high resolution cameras, camera moves can be faked to some extent with pan and scan methods. You shoot higher resolution than the final deliverable will be and you can crop and move 'the window'.

Well, the moves in the video were more like 30 metres long, so I doubt you could pull that off even with an Epic 617!

That video was great. I loved the clouds undulating through the city early on.

Those longer moves must have been done with a western dolly or a small electric cart. You can actually see the speed change a bit, which is a result of pushing a cart by hand. In my avatar, I am actually pushing my friend Matt's Volvo across the NASA Ames research base with my 5D Mark II suction-mounted to his windshield, doing this exact same type of shot.

You don't need "shoot-move-shoot" starting and stopping for most shots, unless the exposures are really long, like over 30 seconds. I am actually moving away from that type of system, and building more "continuous motion" rigs.
