OK Test Results……
We encoded the same clip as Uncompressed 8-bit, Uncompressed 10-bit.

Kona_8bit_Exported_10bit.mov
Kona_8bit_Exported_8bit.mov
Kona_8bit_Exported_None.mov
Kona_8bit_Original_FCP_Encode.mov
Kona_10bit_Exported_10bit.mov
Kona_10bit_Exported_8bit.mov
Kona_10bit_Exported_None.mov
Kona_10bit_Original_FCP_Encode.mov

All files were compared again the original Flame version.
All files had a color shift. Even NTSC Colorbars had a shift

Using another codec doesn’t solve the problem when a client asks for an uncompressed quicktime. Does anybody know about the Kona cards yuv-rgb converion?

we encode mostly from digi (NTSC/PAL) or D5 (720/1080i/1080p) we capture uncompressed 8-bit. The frame ratere is always a little off. so we re-export with “None” compression at that formats correct framerate. When we play it back in quicktime after the export is when we notice the color shift. different from what is on the tape, and the uncompressed quicktime we exported from the flame. (the later two match)
