I've searched the manual and cannot find where is say's the focus point (locked on center point) should turn green when achieving focus. Mine does not. It stays red but does show it has achieved focus and the images are sharp.

That's exactly what happens and what made me ask if it should change in the View finder when taking a photo Steve H.
You're close Joseph. Steve, it only happens in Live View. Take a look at page 50 of your manual, which is part of the Live View section which starts on page 49. I have tested this and it does happen as described in the manual.
Thanks for the reply's. It's a big jump from a D2x to the D4. I'm attempting to take time to learn the in's and outs of the D4 as I am using it. At times there is a glitch or two as I sort through the various settings.
Happy to help any time Steve. I'm still learning the fine points of the D4 myself. For example, last week, I was testing to see what settings worked best when panning for birds in flight. I'm very much a "still" photographer, (That's what I get paid for.) and am concentrating on that in the D4 at this point, but I am very much looking forward to the D4's video capability with which I'm going to begin to work on fully understanding in a few weeks. That will augment my travel photography for very interesting additions in the future.
Interestingly, during a video shoot with my D4 at full resolution in a church in "Movie Mode" and "Face Priority", the LCD display showed the focus point on the bride but it wasn't focussing on the bride - it focused on the people in the pews. It's likely better to manually focus. Perhaps I had something set incorrectly but my video of marriage vows is blurry of the bride and groom but perfect of the bride's Mom & Dad 12 feet or so farther away.
Here's my set up for the D4 video that didn't focus well. Please let me know if there are additional settings needed.
Focus: AF-S; Face Priority AF-C: Release AF-S: Focus AF Activation: On Focus Points: AF 51 Picture Control: Portrait Color Space: Adobe RGB Active D-Lighting: Normal Movie Settings: 1920x1080P, 30 fps Movie Quality: High Destination: XQD ISO Sensitivity Range: A12800 Flicker Reduction: Auto
Joel, this is my best guess as to what happened. I haven't had a chance to test my hypothesis.
I think the problem is "Face Priority."
Nikon states in the D4 manual (p. 53) that "(if multiple faces, up to a maximum of 35, are detected, the camera will focus on the closest subject; to choose a different subject, use the multi selector)"
The D4 manual also says (p. 64) "Note that the number of subjects that can be detected in face-priority AF drops in movie live view."
I can't find in the manual precisely how many faces that the D4 can detect in movie live view.
I think it's possible the D4 Face Priority was overwhelmed by the number of people in the pews and as stated on page 53, defaulted to the closest subject who was in the pews. I'm not sure about the indicator yet. Remember that in movie live view, it's easier to overwhelm Face Priority than when shooting still shots.
All that being said. Can you describe precisely what you saw in the monitor as per how the camera indicated it was focusing on the bride and groom? That will help further thought.
For focusing when trying to photograph birds in flight, I've more or less come to the following settings, but I'm still experimenting with the D4 and probably will be for several more months.
To start, for nature photography I have decoupled the shutter release from autofocus. Pressing the shutter release don't affect focusing. I activate autofocus via the AF-On button. This has been done so I can easily use autofocus to get close to or at optimum focus, and then if essential, finish with manual focus as necessary when focusing on stationary, or semi-stationary birds and other animals.
When I go from AFS to AFC, for flying birds, I don't change that. It's easy to use the AF-On button for all wildlife shooting.
So for panning for birds in flight:
Autofocus Mode: AFC AF Area Mode: 21-point dynamic-area AF Focus Point: Center (Locked)
a1 AF-C Priority Select: Release a3 Focus Track Lock-on: Off a4 AF Activation: Off (As mentioned above) a5 AF Point Illumination, Continuous focus mode: On a5 AF Point Illumination, Focus point brightness: 0 a5 AF Point Illumination, Dynamic-area AF display: On a6 Focus Point Wrap: On a7 Number of Focus Points: 51 a8 Assign AF-On Button: AF-On a9 Assign AF-On Button Vertical: AF-On a10 Store Points Orientation: On
