Awesome, thanks for the tips. Most methods got similar results so far, and
Frank's suggestion is ,as someone else said, free.
Apparently what I have here is a problem on the electronic diafragm of the
DSLR, not exactly light flickering (light source is stable)
and most methods get 80-90% of the flicker solved. Probably I will have to
mix a lot of tricks if it doesn't get solved properly (freezing frames,
local and global deflicker)

I often find that the easiest deflicker setup works best and fastest
for global flicker:
use a frame hold to and divide a blurred version of it by the moving
footage that is blurred by the same amount. Than multiply the result
back onto the original footage:
Group {
inputs 0
name Group1
label "flickering footage"
selected true
xpos -329
ypos -406
}
CheckerBoard2 {
inputs 0
name CheckerBoard1
xpos -166
ypos -317
}
Transform {
rotate {{frame*10}}
scale 1.8
center {1024 778}
name Transform1
xpos -166
ypos -245
}
Multiply {
value {{random(frame)}}
name Multiply1
xpos -166
ypos -219
}
Shuffle {
alpha white
name Shuffle1
xpos -166
ypos -181
}
Output {
name Output1
xpos -166
ypos -81
}
end_group

Hi! Looking for tips and tricks on removing light flicker from stop
motion/timelapse animation in post, any leads?
Nuke preferably, but also open to plugins and other options.
Thanks in advance.
