If you can stabilize your shot around an area that has flicker, this meth= od works very well.

- Crea= te a composition called "average luma". You could make it in a lo= wer resolution to save render time. Drop in your plate and duplicate it. On= the bottom layer, freeze frame at a frame where you have no flicker (or as= little as possible). Apply a blur to both layers and crank up blurriness a= lot. Set the blending mode of the top layer to "Divide".
- Create a compo= sition called "flicker removal". Drop in your plate at the bottom= and the average luma composition on top, scale it to composition size, and= set the blending mode to "Multiply".
- Flicker remove= d.

So if you need= to stabilize around an area, you would probably want to crop the plate aro= und that area and use that to average the luminance. It important that you = linearize your footage and that you work in 32bpc.

If you can stabilize your shot around an area that has fli= cker, this method works very well.

- Create a compositio= n called "average luma". You could make it in a lower resolution = to save render time. Drop in your plate and duplicate it. On the bottom lay= er, freeze frame at a frame where you have no flicker (or as little as poss= ible). Apply a blur to both layers and crank up blurriness a lot. Set the b= lending mode of the top layer to "Divide".
- Create a composition called "flicker removal". Drop in you= r plate at the bottom and the average luma composition on top, scale it to = composition size, and set the blending mode to "Multiply".
- Flicker removed.

So if you need to stabiliz= e around an area, you would probably want to crop the plate around that are= a and use that to average the luminance. It important that you linearize yo= ur footage and that you work in 32bpc.

See attached example.

I have this plugin:

It's decent but not what I would call state of the art.

Subject: [AE] Camera flicker

High speed video shooting has now become pretty mundane. Sony has just
released an update to its F5/55 camera that offers 240fps. As a result of seeing some quick & dirty tests I am triggered to ask what is the best<= br> flicker reduction AE plug that members have encountered? As a minimum it ha= s
to offer the ability to track both moving scenes and differing flicker area= s
within the shot.
