What type of visual effect is used to seamlessly transition from one scene to another by gradually blending them together?

The type of visual effect used to seamlessly transition from one scene to another by gradually blending them together is a dissolve. A dissolve involves fading out the first scene while simultaneously fading in the second scene, creating a temporary overlap where both scenes are visible at the same time. This creates a smooth and gradual transition, often used to indicate a change in time or location, or to suggest a connection between the two scenes. The duration of the dissolve can be adjusted to create different effects; a shorter dissolve feels quicker and more direct, while a longer dissolve feels more dreamlike or reflective. Unlike a cut, which is an instantaneous transition, or a wipe, which uses a distinct pattern to reveal the new scene, a dissolve provides a more subtle and elegant transition. For example, a dissolve might be used to transition from a shot of a character looking out a window to a shot of what they are seeing outside, suggesting their point of view.
