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.
iStabilize stabilizes movies by removing unwanted shaky motion and smoothing the image path. It can separately smooth motion with respect to translation, rotation, and scaling (zooming) in an image sequence.
As a stand-alone software it works independently of other software. iStabilize is essentially a movie player with editing capabilities. It reads and writes many movie formats, such as QuickTime™, (H)DV, MPEG4, and AVI and handles progressive scan as well as interlaced video.
