This is a filter application that uses a video effect called slit scan, which produces an effect that looks as if space-time has been distorted.
It intricately constructs a screen based on frames from the past few seconds of video, and especially if you shoot a fixed-point image, you can create a mysterious image in which a part of the image is distorted.
The slit scan technique is well-known and has been done over, but we tried to find a new way to use it as much as possible. Enjoy!
