VideoMotionReducer app for iPhone and iPad
Developer: differential enterprises
First release : 14 Feb 2023
App size: 2.38 Mb
This app reduces apparent motion of objects in your video clips, both up/down and side-to-side motion, along with rotation... saving changes as a new video; either jitter or major motion (your choice).
New for V1.4: you can choose to reduce only translation (panning) motion, or only rotation motion (or both, as in original design).
New for V1.5: you can choose fill-in background of black, snow, slush, or original image blurred. The snow and slush
is generated from the original image colors from each frame to maintain the same overall color scheme.
It does this by adjusting each frame of the video (shifting it or rotating it) to try to make the apparent position of objects within the video stay where they were originally. Your original video is not modified. You can reduce large motions (default) or reduce jitter / tiny motions, leaving the overall motion aspects of the video as it was originally, with a user-adjustable smoothing control. Additional options to give some control over the background that is used to fill in blank areas, and to reduce only translation motion (horiz/vert) or only rotation motion are now provided. Give it a whirl, give us suggestions!
