Which crossfade is most useful in situations where you do not want much blending between two clips?

In scenarios where minimal blending between two clips is preferred, the most appropriate choice is Constant Gain. This crossfade method maintains the volume at a consistent level throughout the duration of the transition. In a Constant Gain crossfade, the outgoing clip is faded out while the incoming clip is faded in simultaneously, but both clips maintain their peak levels. This results in a distinct transition that avoids the mushy sound often associated with more blended transitions.

The other crossfade options create more pronounced blending effects. Constant Power, for example, modifies the volume in a way that emphasizes the middle of the transition, leading to a smoother blend, while a Linear Fade provides a gradual increase and decrease in volume, creating an even more blended sound effect. Fade In specifically refers to the process of introducing a single clip rather than blending two clips together. Thus, in cases where clear delineation between clips is desired, Constant Gain is the optimal choice.
