most of the time but sometimes you need to lock in your aperture and let the camera do the shutterspeed. The shutter is more reliable than an aperture to control the amount of light let it. So what do I mean? To keep from getting "flicker" throughout the video don't let the lens auto shut down the aperture. Either get a manual lens or set the aperture, press the DOF preview button, and barely twist the lens off the contacts of the body. THen shoot in AV for sunset or sunrise shots and pick the right focus of what you want exposed and that place to expose (like center weighted, zone focus, or whatever).
I always want to do timelapses and have fun doing the composition. It's the post that I hate and have no patience for.
