Battle axe co. and Jake in Motion have a free tool to automatically make smears when animating in After Effects.
Smear frames are a great way to emphasize fast-moving action in animation. Now, there is a free tool for After Effects users precisely for this.
Battle Axe offers a dynamic smearing tool that’s more intuitive than the echo effect in Ae. Called Schmeeer, the Ae tool dynamically adds frames and adjusts the length based on the on-screen motion of a layer.
Schmeeer uses creative expressions to drive the Echo effect as an automatic smear generator, with easy and intuitive controls for dialing in the exact look you need.
