Not sure how else I can explain this...there is no "beginning" cam phaser noise. The phasers either fail to lock and make a loud rattle noise (duration of noise varies), or they lock properly and exhibit no noise. Based on your video, it is not possible that the noise you are hearing is the result of the cam phasers failing to park in their locked position.
As far as the noise you are experiencing, what oil and filter are you running? A missing (cheap filter) or faulty anti-drainback valve within the filter housing will result in a lack of oil pressure to the top end of the engine at cold start. This causes a momentary tapping/knocking noise until the cylinder heads (OHC) or lifters (OHV) receive full oil pressure.
Did you ever observe the wastegate movement on a cold start to see if it coincides with the noise you hear?
FYI, you don't have to explain it (again). I understand the particular "cam phaser parking failure" you are talking about is binary: either working or busted. As I have mentioned earlier I am hoping my "sound" is normal and won't worry about it unless it gets worse. What is worse? Louder. What will cause it to get louder? No idea. Does it matter? Only that I will have a louder noise and will deal with it then.
I also said that no one has posted a sound of their engine in a video in which they believe they do not have the issue. So when someone says "I don't have the issue" for all I know, their engine sounds exactly like mine. To me, it makes perfect sense that in the morning, the oil has drained out of the phasers and, at startup, will rattle until they are filled with oil and builds the appropriate pressure to function. If this isn't correct, no biggie.
I am running stock/original oil and filter and I'm not planning on upgrading to anything outside of stock. I have 2500 miles on the truck. When I go to change the oil, I'll either have the Ford dealer I bought it from do it or I'll buy the oil and filter, based on the manual, from Ford and do the job myself. I don't buy into the whole oil argument.
I did listen for my "sound" from the front wheel well. It's definitely coming from the front of the engine and not the wastegates.
You and others have heard the video. Two or three people chimed in and stated they hear the "rattle" for a second (though very quiet/scaled down) at startup. So clearly, it's there. Let me ask you directly: can you tell me what that brief 1 second "rattle" is when the engine starts? What engine part would create that sound? If you don't know or can't really be sure, that is fine. TIA.
Again, thanks for the help. Like others have mentioned, you're info is desired and appreciated!
normally...i garage park, so i do here sounds because it is so close to the wall and that tends to make it sound loud.
This is over Christmas parking outside and a 30 degree start up. Oil is fresh, less then 2k miles and at proper level.
@goblues38 Thanks for posting this! I have to say my sound is fairly louder and more obvious than yours but I do hear a faint rattle for 1/2 to 1 second at startup in your video.
Now before people get all dismissive and egotistical READ: I am not saying he has an issue. I'm not saying he will develop an issue. I'm not saying his sound is the same as the failure. I'm not saying his is the same as mine. GOT IT? 
Just kidding. Info and discussion is good. Better than silence.
