Final answer:
In adding a shot to a sequence in video editing, two edit points are required: an in-point and an out-point. These define the start and end of the shot part to be used.
Step-by-step explanation:
To answer the question, when adding a shot to a sequence, you typically need two edit points to define a single edit: an in-point and an out-point.
An in-point marks the beginning of the part of the shot you wish to use, while an out-point indicates the end. These two points are crucial as they allow the editor to specify the exact segment of the shot that should be included in the final sequence.
In video editing, creating a successful edit involves more than just selecting the in and out points. The editor must also consider the context of the shots before and after the edit, to ensure a seamless and coherent narrative flow.
While only two points are required to define a simple cut, more complex transitions or effects might necessitate additional edit points or adjustment layers to control the transition's properties.
