Richard Harrington explained the old Color Stabilizer effect more recently in his After Effects tutorial Stabilizing exposure with the Color Stabilizer effect at. ![]() 25% on the textbox is the sweet spot for clamp.” In another direction, on one forum in 2012, Chris Wright said “AE has warp stabilizer for motion and auto levels, auto color for flicker, but I’ve had the best luck with my auto white balance flicker removal project I made a long time ago. The old warhorse is the Color Stabilizer effect, which “samples the color values of a single reference frame, or pivot frame, at one, two, or three points it then adjusts the colors of other frames so that the color values of those points remain constant throughout the duration of the layer.” Auto Levels, Auto Contrast, and Auto Color can be used too. It should be easier than the earlier advice from Dave LaRonde, though adding layers at various time offsets and lesser opacities may still be required on some shots.Īfter Effects has built-in plug-ins designed to remove the flicker common to varying lighting conditions exposed by time-lapse photography and stop-frame animation. This technique was demonstrated by Philip Bloom in Premiere Pro CC in his video Die flicker! Die! How to remove that nasty high shutter speed/ high frame rate artefact in your NLE. In Creative Cloud, you may be able to fix flicker, depending on shutter speed and frame rate, by simply duplicating the footage and dragging the top layer over one frame later in time then adjusting opacity. Use a higher f-stop – Your camera might give less variation at higher f-stops.Make sure the blue channel isn’t clipping. ![]() If it is anywhere near clipping, back off the exposure by -1/3 or -2/3 EV. Avoid clipping – Pay attention to the histogram before you start.Use a shutter of 1/2 second or longer so your exposure captures many power cycles and the fluctuations average out. In artifical light, use a long exposure – If you have to use artificial light, make sure to use a shutter speed that is much longer than one power cycle (i.e.Avoid flourescent lighting – It’s just too prone to flicker.Also useful are general shooting tips from Granite Bay Software to eliminate or minimize time-lapse flicker: ![]() Removing flicker is often easy, but can also be quite vexing with certain combinations of out-of-sync lights, electricity, and cameras routinely used recording time-lapse and slow motion footage.įor discussion of some of the issues concerning luminence flicker (not video field flicker) and how to avoid it, see for example About flicker problems by David Satz, Flicker-Free Lights, and Why They are Important to You from B&H Photo-Video, and Rough Guide to Flicker-Free HD Shooting by Art Adams (more 1, 2) here on PVC.Ī good short guide on the problem is Reducing flicker for stop-motion animation and time-lapse photography by Benjamin Markus on the AE team blog, written before the release of two powerful plug-ins. Removing flicker is often easy but can also be quite vexing with certain combinations of out-of-sync lights, electricity, and cameras found in time-lapse and slow motion footage.Īlthough flicker has had its uses in experimental film, in video flickering can induce epileptic seizures – although it’s mainly just unsightly. Although flicker has had its uses in experimental film, in video flicker can induce epileptic seizures – although it’s mainly just annoying.
