John, I’m no expert but I downloaded your sample file and applied a few Sony Vegas Pro 10 FX’s. First I applied the Secondary Color Corrector, and adjusted the Saturation & Gamma values (see Aberation1 photo). I then applied the Chroma Keyer effect and used the eyedropper tool to select the area with what I think was the worst CA (the blue around the treetops). I then tweaked those controls for best visual appeal (to me) – See Aberation2 photo for settings. I then took a screen shot of your clip, the top half with the above settings applied, the bottom half with the clip as supplied by you. Again, I am NO EXPERT, but I believe my output was better than the original. Good luck.
