Timing & Principles

Line Boil

Also called Boil, Boiling Lines, Wiggly Lines

Outlines tremble slightly frame to frame as if redrawn each time, giving a lively handmade look even when the shape stays still.

Hand-drawn style, wiggly text, sketchy outlines

Prompt

Replace [scene] with the shot and [duration] with how long it should take, then paste the prompt into your AI agent. Each prompt includes the name of the technique, so next time you can simply ask for it by name.

This is for a motion graphics video. Give the outlines in [scene] a "Line Boil" (also called boiling lines or wiggly lines): redraw every line slightly differently every few frames, so it trembles in place even while the shape itself stays still.
It should change in small sudden steps at a low frame rate, like flipping through hand-traced drawings — not flow smoothly, which reads as liquid, and not shift the whole shape around, which is a wiggle.
Keep it boiling for [duration], and keep the tremble small enough that the shape stays easy to read.
