What effect does setting Opacity to 0% have on a clip?

Setting the Opacity to 0% makes the clip completely transparent. This means that the clip will not be visible in the composition or to viewers, effectively allowing whatever is behind the clip to show through completely. In digital video editing, Opacity controls the transparency level of a clip, and setting it to 0% means it is fully transparent and invisible in the frame.

The other options present different effects that are not related to Opacity. For instance, setting Opacity to 100% is what would make the clip fully opaque, meaning it would be fully visible. Enhancing a clip’s colors pertains to color correction and grading adjustments, which does not relate to the Opacity setting. Making a clip play twice as fast involves altering the speed settings, which is an unrelated function to the transparency effect controlled by Opacity. Thus, the statement about the clip being completely transparent is accurate and reflects the behavior of Opacity settings in video editing.
