The cellophane doesn't need removed. Check with the manufacturers and you'll find it doesn't need removed.
I have seen many people leave the strips and say exactly what the video says. They also put the starter course on upside down. I learned right or wrong to trim the tabs off the starter strip and pull the tape off and I have always had good luck with that bonding the first row down.
If it works there I figured it would work all the way up the roof. I was taught always hand nail and never staple or power nail but that is also long gone. The reason I was told to hand nail is you then know the nail went into solid roofing.
After a hurricane you see whole rows of nails shot into sheathing where a truss was supposed to be but they missed etc. There is something to be said for hand nailing and the feed back.
The biggest problem with the plastic strips is they blow around if you let them drop. Like the link shows lots of what I learned went back to the old days.
This is pretty much how I do it but he has the strips removed already.
