Which feature is primarily used to create smooth transitions between clips?

The feature primarily used to create smooth transitions between clips is dissolves. A dissolve is a specific type of video transition that gradually fades out the end of one clip while simultaneously fading in the beginning of the next clip, resulting in a seamless blend. This technique is widely utilized in editing to maintain the flow of a narrative, providing a visual cue that connects two elements, whether they are scenes, shots, or even images. The effect can convey various emotional tones, such as nostalgia, continuity, or passage of time, depending on how it’s applied within the context of the storyline.

While keyframing allows for more complex and customized adjustments over time, such as manipulating effects and transitions in a more controlled manner, it does not inherently create transitions between clips. Speed adjustments can change the timing of how clips are displayed, but this does not relate to blending or transitioning from one clip to the next. Audio fades serve a different purpose, focusing on the audio track rather than the visual aspect and are generally used to create a smoother audio experience rather than a visual transition between clips. Thus, dissolves stand out as the most effective and direct method specifically for creating those smooth visual transitions.
