I have the same problem with the external key on both 4K Extreme and 4K Pro cards using 10.8.3 driver.
The luminance has a maximum of about 92% and minumum of about 7%. White is 92% and black is 7%, whereas they should be 100% and 0%.
I have check the values in the memory I am passing in the alpha byte of the videoframe and they have the correct values of 0x00 and 0xFF.
The keyer level is set to 255. Everything else I have checked is fine. The problem is the key output.
I recently put these into production and this is causing all sorts of keying problems - IS THERE A SOLUTION?
