Real-time video fragmentation — cut a playing video into moving pieces
MOVINdow transforms video from something you edit and watch into something you touch and operate — a technology we call Direct Video Manipulation.
Draw a line across a playing video in MOVINdow and it splits instantly into independent pieces — each one keeps playing, in sync, while you move, zoom, and rotate it freely. This is patented, real-time, on-device technology: no AI, no cloud, no render time. Available free in MOVINdow for iPhone, iPad, and Mac.

Movable video — move it while it plays
Fragmentation has a counterpart: MOVINdow's other patented technology, movable video. Drag, pinch-zoom, and rotate playing videos in 2D, 3D, and 360° — multiple videos at once, all staying in sync. This is also the foundation that lets every fragment be moved freely.
What fragmentation does
- Cut a playing video, live — straight lines, rectangles, circles, triangles, or freehand drawing. Cut before playback or during it, as many times as you like.
- Every piece keeps playing, in sync — fragments are independent playing entities, not overlays. Move, zoom, rotate each one in 2D and 3D while it plays.
- Save & reuse cut lines — store your cut patterns as presets and apply the same shape to any other video. Share cut lines and whole scenes between MOVINdow apps.
- Multiple videos at once — fragment several synchronized videos simultaneously with a single stroke.
- Fragment Clipping — create fragments while keeping the original image intact in the player, rather than cutting those areas out of it.
How is this different from cropping in ordinary video editors?
Many video editors can cut a shape out of a video — features known as masks, mattes, or rotoscoping. But those only overlay a shape on a single stream: the cut-out piece cannot move on its own. In MOVINdow, each cut region becomes a separate, fully synchronized player: it keeps playing while being moved, rotated, and scaled — and can be cut again at any time. The cut is computed geometrically in real time on-device. There is no pre-rendering and no generation time, which is why fragmentation works live, even on a phone.
What people make with it
- Effects no other app can replicate — videos that shatter and split, every piece alive — for social media and music visuals.
- Fragment analysis for sports — isolate the hands, hips, and feet in separate enlarged zones that all keep playing in sync. See sports video analysis.
- Combined with Motion Trails — stroboscopic phases plus fragmentation for entirely new moving-image expressions.

FAQ
- What is Fragment Clipping?
- Fragment Clipping creates a fragment while keeping the original image intact in the player, rather than cutting that area out of it.
- Is there an app that can cut a video into pieces that keep playing?
- Yes — MOVINdow does exactly this, in real time, free, on iPhone, iPad, and Mac.
- Does cutting a video change the original file?
- No. Fragmentation happens only inside the player — the original video in your photo library stays untouched and is never overwritten. You can cut, reset, and cut again as many times as you like.
- Can I keep the result after cutting?
- Yes, two ways: save the whole arrangement as a scene and restore it later, or use crop (shapes, freehand cutout, or face-tracking) to save the shape as a new video file. The original stays unchanged either way.
- Does it need AI or cloud processing?
- No. Fragmentation is real-time geometric computation on-device; MOVINdow itself does not upload your videos.
- Can I use my saved cut shapes on other videos?
- Yes — cut-line presets can be applied to any video, and shared between MOVINdow apps.
