SInES Tools: Video Motion Amplification Tool
(Magnify subtle sub-visual movements in videos based on Eulerian Video Magnification with OpenCV.js)


1. Click on "Start" to set all values on default.
2. Click "Upload Video" to select a video for analysis.
3. Set parameters below or draw rectangles (Regions of Interest, ROI) on the Original Video to auto-detect multiple frequencies in the motion frequency spectrum.
4. Click "2. Start Amplification" to start real-time motion amplification.
5. Optional: Use "3. Record" to record the amplified video and to download it.
6. Optional: Download a CSV export of the motion frequency spectrum with all Regions of Interests.
Target:  (What should be amplified?)
