Chip Chart Color Correction in FCP7
My Sony PMW EX1 has a broken LCD, it’s full of odd coloration, and in a run and gun situation, outdoors, I white balanced and shot a quick chip chart that I often use and went ahead and shot the funeral I was at for a friend. Well, I wasn’t white balanced at all and the shot is so green you’d think the green giant was spraying the scene. Lucky I shoot the Chip Chart.
Does anyone know of a good tutorial or video for color correcting off of a chip chart in FCP7? I do basic 3-way at times, but I need to really work on this one. Thanks for any advice.

Is it just a blown white balance?
If so, use the 3 way CC, select the highlight eye dropper, then choose white on the chart.
Select the midtone dropper and choose grey.
Select the shadows dropper and choose black from the chart.
Should get you in the ballpark.

Thanks! I go through that routine every so often, but this is different. It doesn’t respond to that to my surprise. I’m wondering if the LCD screen was something internal that triggered in the camera. Everything looks super green and washed out. I do have an old Color Correction for FCP DVD by DigitalFilm Tree, but I’m wondering if there is something more up to date. I’m hoping I’m not having camera trouble, but I’m going to test it out now.
So would you happen to know of any updated comprehensive sources for color correction off of a chip chart?

Any chance you can post a couple full res frames of the chart?
A chart corresponds to a waveform for luma and a vectorscope for chroma.
You would have to look at the vectorscope and adjust the color so that the colors line up with the targets.

Yeah, here it is. Thanks for looking at this. I’m getting a sinking feeling about this the more I look at it.

Wow. There is no Red.
Did you have any filters on?

Im no expert here But I think color balance works by doing exactly that, balancing the signals from the different channels depending on the color space you are working (RGB 8bit or 10 bit 422?).
Have you looked at the image through scopes in FCP? Is there info in the Red channel? The JPG has info but it may very well be because you exported it to a different color space it might have made that info up? I don’t know… but I would guess that if the RED CCD is busted and info is not there, there’s no way to fix it because you just don’t have the info to balance.
It might make good black and white footage though. It does have all the luminance info…
Look at the image though scopes and see if you can discover something. Those are my 2cents

Sorry, I should have said little red, not “no red”. My linguistic error!
Yes, it would be better if you could export a few frames in a video codec (like 2 frames of ProRes in a .mov). There’s Red, but it’s all the bottom. The lanyard is reddish.

I’m afraid Jeremy is right, you’ve lost the Red channel from your camera. Time to repair or shop.
