The liquefaction function in AE can achieve the effect of object liquefaction process, and it only needs four steps.
Step 1: Import the material, add the special effect-distortion-liquefaction effect, select the daubing tool to set the parameters, and daub along the flowing direction of the objects in the picture, so as to conform to the development law of things as far as possible.
Step 2: Create keyframes for the distortion percentage, and then modify the picture while observing the keyframe animation.
Step 3: Choose turbulence tools and set parameters to smear details, mainly to make flowing objects have the effect of turbulence disorder:
Step 4: If a certain part is not affected, you can add a mask to freeze it. If you want to make it finer, you can adjust it smaller when using the smudge tool, and you can control the final effect by adding more than k keyframes.
