Summary of Continuity Alerts

Technical continuity	The quality of intercut shots of the same action should match: similar color, brightness, contrast, light direction, shot height, perspective
Environmental continuity	The location should appear consistent from different viewpoints
Spatial continuity	The audience can lose its sense of direction if performers flip from one side of the screen to the other. Space and distance can change with different lens angles
Physical and Action continuity	The appearance of people and the scene should not change noticeably between successive shots (costume, set dressing, props, etc.)
Performance continuity	If a sequence is repeated to provide different shots sizes, angles and viewpoints (for later editing) performers should have similar expressions and make similar gestures in each version. If this doesn't happen, the editors' work becomes a nightmare
Time continuity	Indications of time passing during a scene should be coherent. Watch how food, clocks, candles, etc. change
Event Continuity	Avoid accidental jumps in time or place, when parts of continuous action are missing. Avoid accidentally duplicating action (the Homicide technique of fragmenting and duplicating action increases tension and reveals synaptic time, as does the occasional use of split screen duplication of action). Watch, too, that a performer does not suddenly relocate after a reaction or cutaway shot.
Relationship continuity	Watch for mismatches in shot size that jump-cut the performer(s) too dramatically around the screen. Intermediate shots help to move from a wide shot to an close up, for example. Again, this variation on the jump-cut technique can work, if used effectively, to indicate changes in psychological or emotional perception or reaction
