sequencing in Adobe AfterEffects

CAMERA MOUNTING:
I mounted a tripod in the (empty) front passenger seat of my Jetta with two legs spread into the corners of the area below the seat where feet would normally be and then put the third into the crack beneath the back and bottom cushions of the seat. I then extended the legs and wound the seat-belt around the legs in some clever configuration trying to reduce the amount of play as much as possible.

BLUR EFFECT:
The blur effect is due to the shutter angle, that is the proportion of time the shutter remains open to the time between the start of each exposure. This is usually expressed in degrees with 360 degrees being a 1:1 proportion, 180 being a 1:2 etc. Many times time lapses are shot with whatever shutter speed seems easiest to use and this is usually a very short one during daylight so a video like this would look much different with much less fluid motion. This was possible because of the use of a neutral density filter which is a dark piece of glass that reduces the light reaching the camera without effecting image quality or changing color balance.

SHUTTER LAG:
As to how I shot this at 0.6 second exposures every second without shutter lag: one thing to keep in mind when shooting a JPEG mode for time lapses is that the camera's internal processor bottlenecks your capture rate even though the resulting smaller image can be written faster to the card. This is because while the RAW image may be much larger in size than the JPEG most CF cards can assimilate that data faster than the cameras processing unit could compress it. Under normal (not time lapse) circumstances this bottleneck is mitigated by the internal buffer in the camera which stores the RAW data of each successive image while the processor races to keep up and it does so while you are not shooting. However with continuous shooting like this the buffer fills up and the capture rate drops and worse becomes erratic. I shot in the smallest RAW setting which gave me the greater editability of RAW as well as faster frame rate.
