The video includes a bad mistake: it says the focal length on an APS-C sized sensor would be 45mm, which is outright bullshit. 28mm is 28mm of focal length, that's physics.
What changes, depending on the size of the sensor, is not the focal length, but the angle of view. And this length offers an angle of view comparable to a 45mm lens on a full format sensor.
