eliminating color bleed/rainbow effect

I am not a professional editor but I have used FCP quite a bit over the last couple of years to edit my underwater video. I am shooting SD miniDV NTSC. My monitor is just a small 13' color TV and I know this is less than ideal. Occasionally, when shooting with natural light, I'll have a clip where the colors tend to bleed or cause a rainbow effect when viewed on my external monitor. For example, I have a clip of a sea snail called a fingerprint cythoma where this occurs. It has an intricate pattern (like a fingerprint, hence the name) and the bleeding only occurs around various portions of the pattern. Is there a filter I can apply to reduce of eliminate this annoyance. Thanks in advance.

Try adding the color corrector, and moving the SAT (saturation) slider down a touch.

Steven:

By a chance is not a Moire pattern what are you getting?

I'm pretty sure that is after seeing this Fingerprint Cyphoma picture !

It's a pattern resulting from thin lines in the image combined with the thin lines of the video fields. You could try using a very small Gaussian Blur (very small!!). There is no a magic formula, you must play with your footage to get the best result.

Search in the forum for another Moire related threads.

Hope that helps !
