Hello Adrian,
Thanks for pointing this out! Instructions for this technique have been
added to an upcoming version of the Nuke User Guide.
Cheers,

To eliminate flicker you can use old Shake technique with curve tool. In Nuke
there is curveTool node but manual to Nuke is useless in this case. But you can
refer to Shake manual because PixelAnalyzer in Shake and curveTool in Nuke are
similar.
In few words: with curve tool you can automatically analyze changes of
brightness on selected region of your footage. Then you can invert the result
curve and apply them to multiply in Grade node to counterbalance.
The concept is similar to inverse track to stabilize footage but instead of track X/Y
position changes, you "track" changes of brightness.
You will find detailed description in Shake's manual.
Best

yes there is camera movement. the time blur node. ive not encountered
that before what numbers do i put into that, thats basically averaging
the frames correct?
so if it pulses every 50 frames i enter 50 in the divisions box?
i presume i will get double imaging as ive got a camera move and
moving characters?

If you can figure out the timing of the pulsing (ie. 10 frames or 50 frames)
then you can figure out the numbers to put into a TimeBlur on that frequency.
In general, you're going to want to stabilize your image as much as possible so
that it's only comparing like parts of the frame, but in this case with the
super high frame rate I'm guessing there's no camera move to speak of.
Hope that helps

Hi
Ive been given some super slow-mo phantom camera green screen footage.
Its super super slowmotion which is very very grainy.... and the
footage is also flickering/pulsing regularly throughout....
Has anybody had any experience with this kind of footage and its issues.
Ive tried neat video and furnace denoise/degrain and deflicker....to
remove these issues.
But have not have much luck, the grain becomes quite clumpy whcih is
obvious as i need to keep fine details in the reflections of my shot
...
any tips on alternate methods to denose and deflicker other than those
mentioned would be a great help...
thanks
patrick
