I’m trying to create a motion blur effect on a movie by blending the last 5 frames.
Currently I’m doing it by creating a buffer and draw the last 5 frames on top of each other with a lower alpha value with ofSetColor(r,g,b,a). This creates the following effect (you can see the rotor in the picture being blurry) which is already quite nice. But I wonder if this is the best way to do it.
Does anyone know a better way to achieve this effect. May be with OpenCV?
