Deflicker

The Deflicker plugin 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 plugin can often repair problems
once considered 'unfixable.'

Main Parameters

By default, the top section of this plugin exposes a single control, which in many cases may be
all you need.
Deflicker Setting 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 'temporal NR' controls at the
heart of this plugin to let you tailor it further to your needs.

Temporal NR

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.
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.
