Can clipping be stacked?

Of course. In cropping, the stack is superimposed. In the creation, click on the video, slide the cursor to the part to be superimposed, add the video to be superimposed, and complete the superposition requirements. Superposition is to superpose multiple photos of the same scene taken by the same camera and synthesize a photo according to a certain algorithm, so as to achieve the effects of noise reduction, debris removal, simulation of slow doors and fusion of scenes at different times. Widely used in landscape photography and starry sky photography, it can be described as the "killer" of landscape experts.
