iStabilize is a stand-alone software video stabilizer for MacOS. It stabilizes movies by removing unwanted shaky motion and smoothing the image path.
Shaking often originates from lightweight handheld cameras, particularly when driven at high magnification. Built-in stabilizers mostly do a good job, but can get overcharged in various conditions. Then, iStabilize can be a helpful utility. Being powerful enough to meet professional demands but also affordable for video amateurs, iStabilize is a valuable extension to many digital video (home) studios.
