Transitions
Transitions are the ways that two shots are joined together. The most common transition used is the straight cut as it keeps the pace of the film going. Transitions are usually used to convey a tone or mood or to suggest the passage of time.

Dissolve
This is a gradual transition.
It can help with the continuity.
It can show movement from one location to another or it can show the passing of time.

Fade to black/white
This is where one shot fades from or to black and white.
This gives a sense of time passing or flashbacks.

Fade in/out
A shot is faded out to a black screen or from a black screen.
It helps to create a montage effect.
It also shows a progression of time.

Cross-cutting
This is to establish action occurring at the same time in two different locations.
It can also help to create tension.

Wipe
This is where a line moves across the screen showing a transition from one shot to another.
It can be used as a marker of a change in location.

Iris Wipe
This is where a blurry circle sweeps inwards to the middle of the frame, drawing attention to the subject occupying this centre.
This is made by closing the iris on the camera.

Jump cut
This is an abrupt cut between two shots.
It is a transition which appears to jump between the two frames.

L cut
This is where the cut occurs at a different time for audio than for video.
For example, we may hear characters' voices a few seconds before we see them.

Match cut
This transition is designed to completely hide the transition from the audience.
If a character were to walk towards the camera and completely cover it, you would cut to a shot of the same character walking away from the camera.
The cut is disguised by the character blocking the camera.

Diegetic sound 
This is the sound heard from the recorded footage like dialogue.
Diegetic sound can be either on screen or off screen depending on whatever its source is within the frame or outside the frame.          
Another term for diegetic sound is actual sound.

Non-diegetic sound 
This is sound added during editing like sound effects or music.
Another term for non-diegetic sound is commentary sound.


This is an example of some transitions.
