What's good about this system?

Adding afterimages to movies is a very powerful way to analyze movements of sports. However, in the past, it required expensive video players or advanced video editing techniques.

This Motion Echo Player is browser-based, works in any user environment, and is completely free. Just upload your video and the system will automatically add afterimages, eliminating the need for complicated operations.

It is also possible to adjust the video playback speed and the interval at which afterimages are generated according to the performance of the device you use.

Human figure is not cut out correctly

Too rapid movement may cause the human figure to be cropped incorrectly. If this problem occurs, slowing down the playback speed of the video may solve the problem.

Video playback speed is slower than the specified speed.

Depending on your device, there may be a delay during video playback. If necessary, increase the interval value.

Video cannot be played

Please use a video format that can be played in your browser; we have confirmed that MP4 and MOV files will work.
