Motors like that are designed to be run off a switching or chopper driver. They are not designed to be driven of a very low voltage. You can drive them at a current of up to 1.2A.
So you need a stepping motor driver. I am not going to sit through 25 mins of some one droning on an on to find what sort of driver that video shows. I tried scrolling through but failed to find any actual circuit diagram but I suspect it is not the right sort of driver.
Your best bet is to get a stepping motor driver, they are only a few dollers.
Thank you.
I have ordered this board (5 pieces as i have 5 motors) - I did not recieve them yet - I will still need to know which voltage to give it - can you help me with that?
I purchased 5 A4988 Stepper Motor Driver Carrier as suggested by Grumpy_Mike
The polulu board can take more than 24V so I am sure there is no problem there -
What I am asking for still is what voltage the motors take (through the driver board).

That is what I am saying, the motors will take what ever you power the board with. The chopping regulator will ensure that the current is set to the right value.
If you power that board with 24V then the motors will receive 24V pulses. This will be fine, do not worry about the voltage stamped on the motor.
You seem to have a common assumption about stepper motors, namely that they have a specific voltage they operate at. See my probably-too-snarky post here which hopefully explains that you can run a stepper motor at ANY voltage/current, with the following constraints:
you must use a current-limiting chopper drive to prevent an over-current condition from overheating the motor,
don't exceed the motor's insulation limits, this week probably be 100V or more.
Set your current drive to 1A and use a supply of maybe 12V (up to 24V if you want to be able to step faster under load). When you pause stepping (constant holding current), there will be about 2V across the winding resistance and the remaining 22V will be taken up by the inductance of the coils, at 1/12 duty cycle , averaging to zero. While the driver switch is on (1/12 time), there is +22V across the inductance, and then when it's off (11/12 time), there is -2V, so the current will remain steady.
