color banding when shooting in daylight - MK II
on Nov 4, 2013 at 8:03:26 pm

Hello!

I am new to DSLR and color correction. I recently shot a film in Hungary outside in daylight. All of my footage looks great except for a handful of shots shots where only the red roofs seem to be doing this weird blue banding? Could anyone tell me why this is happening and what if anything I could do to fix it? Or hide it a bit?

Thanks so much!

there might be a plugin out there that removes strobing and moire in one go. I don't know. Hopefully someone else can chime in.

In the past, I made a pretty good strobe and moire reducer AE project.

It does it in 4 parts. The only thing is, there's no auto mask. How you track the bad part is up to you.

mask out the bad part
median effect for chroma blur
shutter blur the strobing
vibrance the lost color


AE 5.5 nomoire&strobe

Is there anyway to do it with Final Cut Pro? I unfortunately don't have After Effects. Or is it something that can only be fixed with AE?

Do you know what may have cause it to begin with?

Thanks!

this plugin for fcp doesn't work with red bricks very well

the best way is to download a demo of After Effects or try to get FCP to use a tracked mask, median filter set as a color transfer. It blurs only the color channel.

you can also try some sort of channel mixer, channel blur and use an optical shutter blur on the strobing.
and finally some sort of saturation boost to recover the desaturated chroma blur.
