Step 1: Open the clip app normally, start creating and import the video. Step 2: Enter the main editing interface and select the "Special Effects" button at the bottom of the screen. Step 3: After entering the special effects interface, we can see that there are many kinds of special effects cut out, such as basic, dreamy, dynamic, dazzling, light and shadow, retro, textured, cartoon, split screen, natural and bordered. Then the effect we need is the special effect of "lens magnification". First, we need to move the vertical blinding on the video to the position where we need to add special effects, and then select "lens". Step 4: We can drag the effective range of the effect in the special effects editing bar to extend the effect time.
