Different transitions and shots

There are many different transitions that can be used for creating my film.
For example:

'The most common transition is the cut, in which one shot changes instantly to the next.
The next most common transition is the crossfade (AKA mix or dissolve), where one shot gradually fades into the next.
Advanced transitions include wipes and digital effects, where shots whiz about or do complex changes whilst leading into the next.'
(Video Transitions, http://www.mediacollege.com/video/editing/transition/)
Fade to black, this is where the scene fades to a black screen.
Fade from black, this is where the scene is shown from a black screen.

However, even though there are many different tranisitions I could use for my film, I do not think I could fit them in, mainly because as the film is only 15 seconds long, there will not be anough time to allow for me to have transitions and make them look professional. Therefore, I will be only using the cut transition, mainly because I have to make my idea seem exciting and maybe have a twist, and to achieve that effect I will have to use the cut transition.

There are also many different types of shot/angles I could use for my film to get the effect that I would like to achieve.
There are:
Long shot: This is where the whole subject can be seen in the shot.
Mid-shot: This is where the camera is closer then the Long shot, however still having the background.
Close-up: This is where the camera is mainly focussing in on the persons face or any other part of the body, with a lot of detail.
Extreme Long Shot: this can be used as an establishing shot.
Extreme Close-up: This is where the shot is very close to the subject showing more detail then close-up.
Over the Shoulder shot: This is where the camera is placed behind someone's shoulder, and looking at the subject, whilst keeping the shoulder and head in the shot.
Point of View shot: This is where the camera is acting like the subject and giving the viewer a look at what the subject is seeing through their eyes.

There are also different angles at which the camera could be placed.
These are:
Low Angle: This is where the camera is placed below the subject, giving the impression that they are big and powerful.
Eye range Angle: This is where the camera is straight on to the subject, a if in real life.
High Angle: This is where the camera is placed above the subject, giving the impression that the subject is small and les powerful.
Birds Eye View: This is where the camera is placed directly above the subject, giving 'birds eye view' of the shot.
