How to Make a Polyester Edit on Mobile: Step-by-Step Capcut and Alight Motion Guide
By Sarah Jenkins
Creators seeking more technical distortion often move from CapCut to Alight Motion. The vector-based editor allows granular control over coordinate transforms, mathematical easing curves, and channel separation.
Begin by setting the project resolution to 1080x1920 at 30 fps. Lowering the frame rate from 60 fps to 30 fps intentionally accentuates visual stuttering. Import your clips and add a Null layer (Object layer) to control camera movements across multiple video tracks simultaneously.
Apply the Displacement Map effect to your video clips. Animate the magnitude parameter using harsh linear keyframes rather than smooth bezier curves. By setting the displacement keyframes to snap between -150px and +200px on every musical downbeat, the footage stretches and snaps like elastic.
Next, introduce the RGB Split effect. Increase the offset distance to roughly 0.015 to pull red and cyan channels apart at the edges of the frame. When paired with the Oscillate effect set to high frequency and moderate angle, the composition vibrates continuously, delivering the hallmark aesthetic of an overedited digital parody.
