An FFGL effect that photographs a clip the way a photo-finish camera photographs a race: one column of sensor with the film moving past it, so the picture's horizontal axis is time rather than space. The streaks, the stretching and the backwards runner all come from that one swap rather than being drawn on top.
This demo runs the plugin's shaders in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
