Deflicker (Studio Version Only)
Introduced in DaVinci Resolve 15, this plug-in replaces the previous Timelapse Deflicker filter,
and solves a far broader variety of problems in a much more automatic way. The new 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 Setting pop-up menu: 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. The default, 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.
