Many might write this off by saying "its a different world" (in NZ) and there's little if anything compatible with DMQ Best Practice to be taken from the video.
This may have some truth for those intending to get their deer into the UK food chain but if you only have the option of home consumption and with zero facilities for breaking down a beast, then with a few 'adjustments' to his approach including greater care in the skinning process the video is worth watching.
Just keep in mind you're not wedded to his process and you need a hygienic means of transporting each cut from woods to vehicle. Safe and meaningful disposal of the bits you don't want including guts & pluck needs no less consideration. Chucking the ribcage and spine into a hedge for your dog to have a chew won't cut it!
There are some very relevant geographical difference between here and Europe/UK that make how we do it the sensible option for NZ - and of course your mileage will differ.
Unless you are shooting on the back of a farm, vehicles are almost never an option for carcase recovery. A million years ago when I was shooting commercially I carried huge weights over very rough ground - and now I've got the knees and back to remind me of it. For commercial purposes the carcase had to have the head off but ears attached, all of the digestive system out and the rest of the offal retained for TB testing. Nowadays the average guy can't commercial shoot due to tighter regs around time to a chiller, food handling courses etc. etc, so nearly all deer shot by Joe Public end up in their own fridge.
With that in mind, and given the nature of the country there is no point in carrying out skin or bones - so it gets left there. It will melt into the ground in short order, and in large parts of the country pigs will do the cleanup within a couple of days. I carry a couple of pillow cases in my pack, and once the meat is boned out it goes into them for the carry out. Typically I don't bother with hanging the deer up - and when Spring hunting above the tree line there isn't anything to hang it in anyway. With the deer laying on it's side, I'll make the first cut along the length of the spine and skin a flap down to expose the backsteak, and peel it off then lay it on a pillow case to cool. next I skin the back leg, cut the hock off and separate the leg from the carcass before it goes on the pillow case. The shoulder depends on bullet damage, and the state of my mince and sausage supplies at home. If it isn't too damaged, AND I need to stock up on mince or sausages I'll take it and the neck meat by the same process of flap skinning and boning, otherwise I'll just roll the carcase over and repeat the process on the other side. No gutting/gralloching required, and the process takes very little time. While the meat is cooling I'll have a drink, eat whatever food I've carried in then put the meat inside the pillowcases, put them into my pack, harden up and walk back to the car.
The sika in the below photo was 7km from my car (including 1.5km walking in a creek), and I was home in bed that night with all of the useable meat in the fridge. My vehicle is at the base of the ranges to the left of the branch of the bushes behind the deer - and there is no track, just a route I've figured out during 35 years hunting there.
