If you already have a video editor that allows manual stabilization, then this app may be redundant. However, for manually stabilizing video on an iPhone, this does the job really well!
I don’t think it’s really for removing vibration or shakiness, but the iPhone camera removes that already.
If you have video similar to the sample in the App Store listing (with the dog), or if something keeps moving out of the center of the frame, or the camera was moving around a lot, this lets you manually readjust every time that happens. In the end, your subject will stay relatively centered in the video.
My only gripe is that if you move the video too far from the edge, it reveals a checkerboard pattern. It would be great if there was an option for this to just be a black border instead.
Great app that does what it says it does!
