David,
Thanks for viewing it and responding.
I’ve found part of the solution: changing my QT preference to “Enable Final Cut Studio Color Compatibility” seems to return the general level of the black to what I saw in FCP.
Now onto your good questions.
1. Apple 30″ Cinema display
2. Stock, not calibrated
3. Yes, but I didn’t always pull the blacks all the way down.
4. The source is footage from an Sony EX1 shot over the past 10 months at a wide variety of settings, HD formats, exposures, and white balances.
5. Sequence settings: 1280X720; 16:9; Square; XDCAM EX 720p60 35 Mb/s VBR; Quality=100%; 8bit YUV
