Learn more about how Video - Motion Tracker works under the hood.
Traditional video stabilizers or manual motion tracking tools translate the video frame around, exposing unsightly black or transparent borders around the edges. Our app dynamically computes the exact geometric scale required on every single frame so that even with motion compensation, the video frame always stays 100% full-bleed.
No! The tracking engine automatically analyzes inter-frame optical flow and temporal differences to identify moving subjects (like runners, dancers, vehicles, or sports players) across the entire video automatically.
Exported videos are automatically saved to your phone's public Movies/MotionTracker folder via Android's MediaStore. They will immediately appear in your Google Photos, Samsung Gallery, or default video player app.
Never. 100% of frame processing, optical flow analysis, and hardware video encoding happens locally on your Android device. We have zero video servers and never collect your media files.
When you first launch the app, a language selection prompt lets you choose English or Hindi. You can also tap the Settings gear icon at the top-right of the screen at any time to switch languages instantly.
