I make (coloring) a documentary movie and i have a lot of footage that has banding from wrong shutter speed , i suppose.
I upload a small portion to see it.

I tried all known methods, plugins etc but i cant remove it...can you help me please ?
I have studio version, i tied deflicker / deband and a plugin in after effects , deflicker v2.

Nothing works...is there any solution ?

Looks like bands are in same position all the time, I’d try grading them out. Create soft masks for band areas and increase exposure. Fixed pattern is probably the reason why all deflickers etc fail.

Ok.... I will try it.



EDIT... i just tried but i realized that bars are moving, they are not static.

Try adding some animated noise. Although the deband filter is pretty good. If that fails adding noise may not help much.

i tried everything... not working.

If someone tries something with success , i would like to know .

There is a DeBand effect.

Never tried it myself.

i tried it, it doesnt work in this case.

Bummer.

You may find yourself running into an often overlooked reality - not everything can be fixed in post. Sometimes, you have to shoot it right.

If a banding look like slow light flicker, use the deflicker tool in advance mode.

Post a little clip of the issue so we can help better.

It's not banding and not a single de-band filter will fix it.
It's some scanline problem. Combination of shutter speed vs lighting etc.
Not easy to fix.

i putted one link in first post... you can try and see.

My bad, I missed it...

That is really difficult to to fix... especially if those bands move very slowly...

yes, i know....

An idea (havn't looked at your clip):
The Fusion tracker gives you more flexibility for this type of problem.
Got to Fusion tab - create an extreme contrast that makes the bands visible as much as possible.
then track a band on a portion where its most visible with planar tracker, just using x and y curves.
With curve editor zero out the x graph, then manually clean up and extrapolate the y graph - assuming that the travel speed is constant. and fine tune it to get the best possible match.
Then apply the y movement to a mask that separates out the bands and then lets you correct out the difference.
A fun challenge - or not.
