help to fix clipped footage

Hi,

I have this multicam project and one of the angles is clearly blown out on the highlights.
Is there a quick way to minimise the damage?
Here are the pictures of the bad footage and a good one.

Is it possible to make the clipped footage look approximate to the good one using color finale for instance?

thanks
joni

I dare to say there's no way, quick or slow, to fix clipped clips.
The signal contains zero info, so no way to re-enact structure, texture in the plain white parts...
for the rest of the picture you can make it match to other material…

actually in the making of some 'brithday video', same here with stills.... there ARE tutorials, applying surrounding colors. blur, tons of 'tapping'… but for plain skin aereas, e.g. foreheads; a blown-out hair would ask for cloning on some genius level.

That shirt has no 'surrounding color' nor any texture you could clone to....
sad news, I know :(

Plan B
apply a hefty 'Look', Instagram-ish filters, hiding the mess under a thick layer of eye-candy... that's what I'm doing here with damaged snapshots...

Thanks Karsten,

I know there is no fix ;-)
I am just trying to minimize the problem.
I am using LUTs to the whole think, and some correction on the clipped angle...
Not at all OK but better...

My sympathies; we have all been in situations like this. As Karsten said, in either stills or video once the highlights are blown there is no data.

There are several things you can try but none of them are going to work that well:

(1) Use the built-in FCPX Match Color feature: support.apple.com/kb/PH12675?locale=en_US&viewlocale=en_US

(2) Use Hawaiki Auto Match, which is a more sophisticated version of the above. It can match based on multiple sample points. However it is procedurally tricky to use: fxfactory.com/info/hawaikiautomatch/

(3) Look at the waveform monitor and flip between the two scenes with the skimmer, and use the color board or Color Finale to get the waveform monitor more similar between them.

(4) Colorista III has a highlight recovery feature. I have never used it but it's demonstrated here: www.redgiant.com/tutorial/red-giant-quic...-highlight-recovery/

(5) Try selectively darkening the white shirt with a mask.

(6) Blow out the over-exposed shirt further, then blow out the good shirt to match it. Use additional effects such as light leaks, volumetric lighting rays, lens flares etc, so it appears to be a planned artistic effect. E.g, you could have volumetric lighting rays coming off the shirt using this plugin: www.motionvfx.com/mplugs-82.html

The problem is your wish to do this "quick". These things can become a lengthy trial-and-error graphics art project.

Hi Joni
Are these just stills? What format are they? Is it possible they are RAW? If so you might be able to recover the details, JPEGs nope.
I would correct them in a photo editor and then reimport. Photo editors may give you increased controls for repair. I typically use Pixelmator.

Hope this helps, Greg

With digital recording, once you go over 110% white, there is no data to describe that value, it is not recorded, the only way is to try and color correct to a degree, but sadly, the actual color was not recorded by the camera, it cannot, impossible, it is just beyond super-white.

This happens if you use the color viewfinder/small monitor without zebra strips, you cannot see if the white is beyond the range of the codec to know about.

This is one aspect of FCPX that I miss, in old FCP you could see overbright, and the app would "grade" the overall white with a green tick, then you knew you were ok with the levels.
