Mark is 100% correct. How you cut from one shot to the next is absolutely critical and follows on naturally from WHY you cut from one shot to the next.
I'm no expert - I'm only at te very beginning of the learning curve with this stuff, but here are a few pointers.
As indicated above, you should cut from one shot to the next because you have a reason to do so. If you have a reason the cut will be expected and so it will not jar so much.
Example: Actor A enters a scene and holds out his hand which contains something which he shows to Actor B. We cut to a close up of his hand/object. We then maybe cut to a close up of Actor B to see his reaction and then another cut to Actor A to see him watching Actor B's reaction.
All these cuts have a purpose - they are all where we would expect to focus our attention and because they are expected, they are smooth.
Cutting between shots simply in order to provide variety is perhaps a bit more tricky. Try still to come up with good reasons for the cuts. Take something like a film of a stationary steam locomotive. Don't simply stick random close-ups and wide shots together. Suppose you want to show the name plate (on the side of the boiler) in close up. Show the whole loco first, then a mid shot of just some of the boiler (with the name plate in view) and then the close up. If these are filmed from the similar angles this will focus the viewers attention on the name plate and the cut's won't jar (though filming from different angles may make it more interesting). Then go out to a wide shot again before focusing in on another detail.
There are a lot of mechanical consideratiions if you want smooth cuts.
Try to ensure two adjoining clips have the same colour/contrast etc.
Look for matching "shapes" in both clips (eg an arch of a bridge and the top half of a clock)
Don't cut into or out of a moving pan or zoom.
Dont cut between two shots of the same subject taken at similar angles or similar distances.
Don't forget sound. Either the recorded sound or a soundtrack will often define the "right" point for the cut.
Use J or L cuts (where the sound track changes before or after the video) to smooth cuts.
These are just some ideas off the top of my head and I haven't even read the fourth "C" - cutting, in Joseph Mascelli "Five Cs of Cinematography" as recommended by Mark W, yet.
