Cool vid, but calling that a 'start up' is a little misleading. There's much more going on there than starting the engines. Modern turbine engines are pretty automated and don't require much more than the push of a button (starter) and flip of a lever (fuel) to start.

Private pilot here (who's also ridden in some full-scale airliner flight sims). A lot of the procedures in the video are going through checklists to test the various instruments and systems, both normal and emergency ones, as well as entering the route in the flight computer (used by the autopilot). This is what real pilots on real flights have to do.

If you just want to start the engines, taxi, and take off for a joyride (completely violating company/FAA policy), the steps are quite a bit less although still involved, depending on how old the aircraft is and the level of automation it has. This video seems to show a 737-800 or later, which is pretty new and most likely has a system that with one or two buttons handles the bleed air/ignition/fuel sequence of starting a turbine.

It's not because "start up" doesn't mean they're just turning on the engines, but means they're running through the start-up checklist. This is far more than just starting the engines, and includes configuring the plane and testing to make sure essential systems are okay.

There was a good thread on the /r/flying subreddit discussing this procedure yesterday. Specifically, poster /u/veritasiness outlined the entire procedure step by step [1] which I'll cut and paste here:

  0:02 ground power turned on. The plane is basically "plugged in" to an outlet. This 
       turns on the electric systems from that power source.
  0:03 cabin / utilities on
  0:05 voice recorder check
  0:06 turning on (aligning) IRS
  0:10 Fire checks (Bell, loop, fault)
  0:12 Extinguisher checks (3 bottles)
  0:13 Cargo extinguisher checks
  0:15 Oxygen mask check (demand only / emergency)
  0:20 Audio Selector Panel setup. Buttons on the top are the options for transmitting. 
       Knobs on second row are options for listening.
  0:30 FMS setup (also part of aligning IRS Navs)
  0:34 Manual route entry. Left side are the airways (roads) and right side are the 
       fixes (intersections)
  0:40 Arrival Setup. Left side are the STandard ARivals. (STARS) Right side are the 
       actual runways approaches.
  0:44 Fuel pumps on.
  0:45 engine driven and electric hydraulic pumps on. Note: several operators leave 
       the A side off for push back because nose wheel steering is commanded by 
       A-Side hydraulics. There is also a bypass on the gear as an alternative to 
       shutting off the A-Side.
  0:48 overspeed warning test. (clacker is what goes off if you overspeed the plane 
       and is an indication of a good check)
  0:50 window heat on (1 for each window)
  0:52 AC setup
  0:54 setting cruise altitude on the pressurization panel
  0:55 setting landing altitude
  0:58 Flight director on. ("MA" is master. It's the copilot's leg to fly)
  1:01 Autobrake to RTO (Rejected Take Off)
  1:06 cockpit light check
  1:10 transponder to 2 (It's the copilot's leg)
  1:19 GPWS check
  1:30 Hyd pumps off (see above)
  1:31 AC packs off
  1:33 beacon on
  1:35 pilot cooling fan #2
  1:58 ignition switches to ground (starts the engine turning)
  2:02 fuel switch on (introduces fuel to the engine). Also how you shut the engine 
       down.
  2:06 N2 rotation - speed at which the engine is turning. Fuel is typically 
       introduced at 25% N2. Too early / slow and you might get a hung start. 
       Or a hot start.
