Per,
This is sad to hear because I am going to pick up my new HVX200 this week.
What you discribe sounds just like the problem I had with my on line Prodigy switcher. No matter how much I tweak the chromakey clip and gain there was always “crust” green edge on the left side of the the talent. Then one day I got the engineer to visit, I showed him the problem, he scratched his head, studied his engineering drawings of his install and got out his trusty tweaker. And everything was Perfect… The problem was that the “hole” cut in the background was “out of blanking” (sync) with the keyed foreground. Once he fixed the “blanking” problem due to a cable being 3+ inches too long, everything was very pretty.
But if you are using Ultimate software and the computer, I have no idea how one would address a blanking error between the keyed foreground and the hole cut by the chromakeyer. And it smells like a blanking error, because the 3 pixel green crust does not encircle your subject on all sides. Why does it happen on one side and not the other.
Have you tried different colored background for your key color. Is the camera more sensitive to chroma green, than chroma blue, or even 100% white or black.
I am eager to hear the cause and the solution to your problem, too. Because by Friday we will have a HVX200 and hopefully soon we will have the 500 too.
Gosh, I miss the old days when there was always bad cable, or the missing engineer that the client didn’t want to pay for to blame.
