I had same issues when got Kona 3 and FCP 5.1. I spend about 3 days to find reasons why this happen. I will exlane my steps to You and hope it will hwlp You too.

1. FCP.
Problems root ia AJA Kona 10-bit RGB codec. Exactly Color Range Tag. All Easy setups from AJA comes with Capture Presets with compressor settings (You can check it in Advanced menu):
- Type: AJA Kona 10-bit RGB Codec
- Range: SMPTE (64-940) - remember that
But in same time my Sequence Presed had:
- Type: AJA Kona 10-bit RGB Codec
- Range: FULL (0-1023)
Check Your Capture/Sequence settings. I thing You have same issue with Range Tag in Capture or Sequence. Put all of them to
- Type: AJA Kona 10-bit RGB Codec
- Range: SMPTE (64-940)
- And check "Video Processing" setting for sequence. It must be "Always render in RGB"
- By the way "Pixel Format" must be same too. "Big Endian" for me.
After this will be done only issue will have place: with Black/White shifts when play/stop sequence. In FCP canvases all thinhg will be OK, but You will see shifts in AJA SDI outputs. But all others issues (black frames after render and etc) will be fixed. I play/stop issue is FCP trouble. And if You will set Range Tag to "Full (0-1023)" in Sequence and Capture both You will fix it too. But You need recapture all Yous sources again with new presets (due to AJA defaults which You use before) had SMPTE (64-940) Range Tag.

2. FinalTouch.
Issue same. FT HD render ALWAYS in FULL (0-1023) Range. And If You have old vifeo with AJA Kona 10-bit RGB codec with SMPTE Range tag You always will get Black/White shifts. I fixed this one only with FinalTouch 2K. It have "Printing Density" preference in "Prjct Setting" Tab. By default it render in "Linear (0 Black - 1023 White)" mode. But if You change "Render File Type" from DPX to QuickTime and then back to QuickTime You can change "Printing Density" to "Video (64 Black - 940 White)" and then render without Black/White shifts . . .

System where this issues was fixed: MacPro 3.0/4GB RAM/ATI 1900XT/ Apple FC 4GB board/Ciprico MediaVault/FCP5.1.4/QuickTime 7.1.5/ FT 2K 2.7 RC 2/ Kona 3.3 Driver
