Deflicker
In the ‘ResolveFX Revival’ category of DaVinci Resolve Studio, the Deflicker plug-in handles
such diverse issues as flickering exposure in timelapse clips, flickering fluorescent lighting,
flickering in archival film sources, and in certain subtle cases even the “rolling bars” found on
video screens shot with cameras having mismatched shutter speeds. Two key aspects to this
filter are that it only targets rapid, temporally unstable variations in lightness, and that it’s able to
target only the areas of an image where flickering appears, leaving all other parts of the image
untouched. As a result, this plug-in can often repair problems once considered “unfixable.”

Main Parameters
By default, the top section of this plug-in exposes a single control, which in many cases may be
all you need.
‚
Deflicker Settings: The top two options, Timelapse and Fluoro Light, are presets that
effectively eliminate two different categories of flickering artifacts. If neither of these
presets is quite as effective as you’d hoped, a third option, Advanced Controls, opens
up the Isolate Flicker controls at the heart of this plug-in to let you tailor it further to
your needs.
Isolate Flicker
Hidden by default, these controls only appear when you set Deflicker Setting to Advanced
Controls, and let you choose how to detect motion in the scene so that flickering may be
correctly addressed relative to the motion of subjects and items within the frame where
it appears.
‚
Mo.Est. Type: Picks the method DaVinci Resolve uses to analyze the image to detect
motion. Despite the names of the available options, which options will work best is
highly scene dependent. Faster is less processor intensive, but less accurate, however
this can be an advantage and actually do a better job with high detail images that
would confuse the Better option. Choosing Better is more accurate, but more processor
intensive, and Better will try harder to match fine details which can sometimes cause
problems. None lets you disable motion analysis altogether, which can work well (and
will be considerably faster) in situations where there’s no motion in the scene at all. The
default is Better.
‚
Frames Either Side: Specifies the number of frames to analyze to determine what’s
in motion. Higher values are not always better; the best setting is, again, scene
dependent. The default is 3.
