Hi!
I have tried to find out proper way to smoothen luminance changes on
videos of sunset. Cameras are action cameras where it is not possible to
set manually exposure etc, and in fact, it is not desirable. Typically
my video recordings are few hours, from full daylight, sun shingin
towards c

towards camera, and endig to darkness. So exposure changes gradually,
but problem is that on such cameras, change is annoying clear, sudden
change. Therefore, I'd like to smoothen that so that it is not that sudden.
See example what I mean

One option is to write all frames as pictures to disk, and then run
timelapse-deflicker.pl for them, and make video from those pictures.
However, that will take much time and disk space

Maybe I try to create script which would get frames as pictures. And in
addition, to darkest parts of the video, there is huge noise in picture,
averaging maybe 4 frames migth give better results.
Made a script

I'm pretty sure that ffmpeg can't do that, as I know of no filter which
will create such an average and apply it. But a filter could be
written... I don't know if it would be a candidate for upstream though.
I just wrote deflicker filter.
Sounds great!

Sounds great! Do you want some tester for it?
Yes, Do you know how to apply patches and build master ffmpeg git?
Haven't build ffmpeg

Alternatively you could provide me link to original fotage.
I'll select relevant parts and put them to somewhere at the evening. The
whole original set is 15G (video was speeded 300x).

From http://scl1.tavasti.fi/~tavasti/ you can find 3 video clips for
testing. Create video from them like:
ffmpeg -f concat -safe 0 -i <(for i in FHD*MOV; do echo file $(pwd)/$i;
