- Cuts : the most common way to join two clips together.
types of cuts: match cut, L cut, jump cut, etc.
- Fades: this occurs when a picture becomes a single colour, most of the time black, or when a picture is occuring on screen.
types of fades: cross fades, fade in, fade out, etc.
- Dissolves: similar to a fade, but instead of becoming a single colour, it gradually changes to the next scene.
types of dissolves: additive dissolves, cross dissolves, ripple dissolves, etc.
Final Cut Pro also has a range of transitions such as adjusting colour, blur effects, and negative/sepia effects. We wanted our film to look quite realistic so we stuck with mostly cross dissolves and the classic fade in/fade out.
Here's a clip I found of youtube about transitions and the great effect they have on films.
