Weird Color Shift when adding lower third…
I shot a video using a canon 7d. Footage was converted to prores 422 and imported into final cut. After I had my cut done, I graded the footage in Apple Color and sent it back to Final Cut. Everything looked EXACTLY how I wanted it. The last thing I did was create a lower third in Motion that I then imported into FCP. Here is where the problem occured:
When I layed the third in V2 over the footage, it slightly changed the color of the footage underneath. It added a slight magenta-looking hue to the skin tones. The colors then shifted back to how they should look AFTER the duration of the lower 3rd had ended. I have tried exporting the video without the 3rd and reimporting to THEN add the 3rd, but the same thing is happening. I thought it might be a problem with my motion file, so I created the same third in Photoshop without animation and brought it in. SAME PROBLEM!!! I’m going crazy here and I have to have this video delivered in a couple of hours. Any suggestions????

I have run into similar problems to this when working with alpha channels, but I’ve never used Motion.
One thing to remember is that transparent pixels in images and video are not actually transparent, they are colored pixels that are matted out by the alpha channel. Sometimes they are matted out all the way in one program, but still show through a little in others.
This kind of thing happens in after effects when people work with colored backgrounds but then export them as transparent.
What makes this seem strange to me is that it happened out of Photoshop. I’ve never seen it happen that way.
Is there anything in your Motion/PS project that is magenta, or is this totally out of the blue?
Also, is your PS project in CMYK of RGB?

Click in your timeline, and click Command 0 (zero) to open up your setting, than go to quick time settings at bottom left, and click on the “advanced” button, once in there go to “gamma correction” and un-click automatic and change it to “none” this seems to have gotten rid of the flicker for me! Let me know if this works for you.
