Color correction trouble
I have some otherwise very nice SD fotage in which there’s a white balance shift at a pretty regular interval. (camera malfunction I think) I only need to warm it up every few seconds and let it go back to normal, so it needs to be keyframed. I can sort of get it with the color balance filter, figure the color corrector would be better, but can’t figure out how to shift it. Any clues?

Chris,
I tried one time to do something like that but was very difficult because all the footage was wrong. It had two different dominats.
But if your footage is correct in some places and you have to correct only a dominat color in some areas I think you can get it with the 3-W CC. Set key-frames in the beguining and end o the pieces of footage that need to be shifted in color. I think if you can correct one of those areas, then you can apply the same values to the rest of the wrong footage. A bit of time and patience. It may be a more easy and proffesional way, but I don’t know it.
Hope you understand my “terminator’s” English.

Yes Rafael,
One area is “correct” and it drifts in and out of it, very regular in time, and your method is one that I have tried, but it is tough. I was hoping someone could show me how to take the white balance from the “correct” area and apply it to the “wrong” area, and let FCP interpolate the in-between areas. It works okay in theory in my head, the problem is getting it down on tape.

Chris,
I’m sitting in a hotel in Guadalajara Mexico waiting to start my day on a shoot,
so I may be off a bit on my advice without FCP in front of me, but I’ll try:
Apply the 3way CC, select the Auto Balance Color eye dropper on the white
wheel. Choose a pure white in an unaffected clip, then go to an affected clip and select an area that should be pure white. Click there and it should match the other white. If it all happened in one scene you can copy and apply the CC to all the affected clips. If it happened over a number of scenes, do the same thing over again on each clip.
Sometimes, depending on the shift, it can help to extend the adjacent clips, using the shift
as the center point of a dissolve to help blend the clips better. It doesn’t always help, but worth a try.
HTH,

Hi Chris,
Yesterday I was about to write you again, but the credit of my internet pre-paid card finished.
If you don’t have a white, as Ed suggests, you have to make a “Match color” in between a picture with good color and a bad one. Them key-framing and applying the values that you has get in the “Numeric window” of the 3-W CC. The big job is to get the same cadence by key-framing.
