I was just curious what were some of the tricks people were using for time lapse with there BMCC's?

When I'm shooting lapses of waterfalls, the sea etc I usually use a 360 degree shutter to get some blurry motion to it. The same when shooting time lapse of people walking.

When shooting landscapes I sometimes shoot with a 45 degree shutter. Mostly because it rarely affects the image to much (depends on the clouds, though), and it allows me to use a f-stop around f/8 which makes the image sharper. The Sigma 8-16mm is not very sharp over f/11.

Usually, I set the interval at 1 sec and shoot in raw.

Exposure wise it depends on the subject, but I try to avoid zebras (burnt out areas), so if I know the light from the sun is coming in from behind the clouds, I underexpose by two or three stops. And if the sun doesn't appear after all, I can still pull the exposure back up again since the raw files can handle a lot of editing.

I just started playing around since I got the BMCC. I like the 360 effect. But I'm still missing the light streaks from cars at night.

Yeah, those kind of things need several seconds of exposure time.

Any suggestion on how to resolve this?

Use a DSLR for several seconds exposures.

Ain't it possible to shoot 360° shutter (continuous shots) and then overlay a number of frames or stack a number of copies of the same clip? Stacking 24 frames of a 24 fps / 360° clip shouldn't be too different from exposing one second at a time. You even get more DR to work with, as you are essentiall shooting HDR.

You should then set frames for more exposures, right?

I usually go for around 10 seconds of film, so about 240-300 exposures depending on your films framerate.
