Blue overlays in FCPX
on May 9, 2013 at 9:21:59 pm

Hey, we're new to FCPX and wondering what's up with the blue overlays we're seeing on this video. It was shot on RED, and we have the Red plugin. The video plays without the blue in both the viewer and canvas windows, but about a second after it's stopped the blue shows up, and only on the darkest parts. Looks like an excess luma overlay or zebras or something. Anyone know what it is called, what it's for, and how to turn it off?

Thanks, Tom

Not a clue. Sorry.

I agree it looks like something mapping luma values to the screen via false color. I had a monitor card going bad once that did the same kinda thing, but on everything, not just still frames.

I suppose if you can't get it to stop showing up on still frames, maybe you can find a way to get it to show up on ALL the footage - then "motivate" it by having a character drop acid in an early scene?

Seriously, I hope you figure it out - and be sure to stop back and let us know if you do.

Sorry not to be more help.

Ha! I like the dropping acid answer.

I should have mentioned, we thought it might be the monitor and tried it on an external mac cinema display as well as on the laptop itself and it does the same thing. Good idea though.

I am having this same problem tonight. The blue remains on the exported file as well, which leads me to believe it is a weird defect in the Metadata file for the RED footage? Something like that maybe?

What happens if you export to Quicktime?

What does the scope/wfm say?

Yes, definitely still there in the QT export.

Scopes read it as actual blue video. And the waveform isn't putting anything below 0. I have found that if I turn up the blacks so nothing is below 10% or so, the blues go away. It will work for today, as I only have a roughcut due, but any thoughts. A DP friend of mine thought it might be related to noise in the blacks.

In addition, I found today that adjusting the "Shadow" slider in the RED RAW Settings is definitely changing the power of those blue overlays. Much Much less intense if I even turn the "SHADOW" up above .1

Not an answer, but I'd suggest submitting this on the FCP feedback page, with a link to this post so they can see the pics. They actually do look at stuff that gets submitted. :-)

Thanks for all of the suggestions. We'll try messing with the footage to get rid of the blues and I'll submit it to Apple. Good ideas.

Thanks,
Tom

Okay, here's the fix we found.

In the Inspector:
Info
Modify RED RAW Settings
Gamma ->change this to Red Gamma

For whatever reason ours was on Red Gamma 3 which produced the blue effect. Color correction in FCPX afterwards seems to work normally and helps bring the shadows back.

I'm sure it's just a weird workaround, and there's probably a better way to do it, but it looks like it could work.
