lap dissolve
C2Technical/Specialist
Definition
Meaning
A film editing technique where one image gradually fades out while the next simultaneously fades in, creating a brief moment of overlap.
A cinematic transition effect where the end of one shot is superimposed over the beginning of the next, commonly used to suggest a passage of time, a change in location, or a thematic connection between two scenes. It is a type of dissolve (also called a crossfade).
