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 runs on Apple computers with MacOS X (10.4+).
- It supports PowerPC (G4/G5)- and Intel-based Apple computers.
What it does
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.
How it works
With iStabilize the process of stabilization is divided into three steps for best performance and flexibility:
- The movie's motion is estimated. You don't have to specify anchor points, but you can optionally define a region of interest. The new motion tracker of version 2 is fast and more accurate. It tolerates foreground motion very well and recognizes cuts, so you can run the motion analysis over multiple scenes.
- Now it's up to you to adjust a few parameters for computing the optimum image path. This is easy and does not require deep knowledge. The implemented algorithm considers a wide range of frames including a forecast to future frames. Unlike other solutions, you can immediately watch the stabilized movie without time consuming rendering. iStabilize offers multiple zooming options and methods for handling margins. You can stabilize multiple segments of a movie separately.
- Finally, you can export the stabilized movie to a new file. Then, the movie is completely rendered, recompressed, and written to a movie format supported by QuickTime.
