Motion blur3/14/2023 Sometimes the use of motion blur in video games is an artistic choice but more often it is a technical choice that helps to compensate for poor frame rate or rendering issues. ![]() The use of motion blur in video games is a bit controversial but many modern video games do feature motion blur, especially racing simulation games. ![]() Happy Puppy by kajdax Motion Blur Effect in Video Games Rendering nice motion blur is a way to smooth over this visual strobing and flickering problem. Motion Blur Effect in 3D RendersĪ common problem with many 3D renders is that fast motion creates that horrible strobing, flicking effect as objects jump from one location to another between frames. In film and televised images, motion blur looks natural because as mentioned, the human eye perceives and behaves in much the same way. Motion blur is a natural occurrence and as mentioned a limitation of the human eye, which is why we so readily accept film’s frame rate of 24 frames per second (FPS). As a result, lots of processing needs to be done in order to make movies look as nice - as cinematic so to speak - as they do, and motion blurring is a big part of it. When your eyes are looking at something that is actually a series of still frames and not real motion - like anything appearing on a screen - then motion blur can help your brain interpret the image as motion rather than still images. This is basically the bare minimum needed for eyes to perceive it as motion. Motion blur is used extensively in movies because they operate at 24 frames per second. Motion Blur Ball Bounces by School of motion Motion Blur Effect in Filmmaking For example, comparing the simple animated ball bounce with and without the blur motion in the image above, the blurred detail of animation not only does not add anything of value to the image but we also end up losing the feeling of the ball’s weight as well. So what are cons of motion blur in animation? Well, there are instances when motion blur is unnecessary and it takes away pertinent details of animation. When fast-moving images are blurred it helps our brain to smooth out the animation. This simulated motion blur is typically applied when the goal is to imitate real life or when the animation is being composited into live-action footage when either the camera or objects in the scene move rapidly. The good thing about the application of the motion blur effect in animation is that by imitating the blurring that would otherwise occur if the footage was captured with a camera it helps to blend frames and make the frames feel more connected and continuous, so that the enhanced simulation of motion can feel more alive, organic and natural. Typography Animation by Maxym Zakharyak Motion Blur Effect in AnimationĮach frame of animation captures a single perfect still moment in time with zero motion blur ( analogous to a camera with an infinitely fast shutter) which makes the motion feel smooth but it can also potentially feel staggered, artificial and unnatural as well. ![]() Motion Blur is the blurring of the image of a moving object in photographs, film, or video, which occurs when the motion is rapid in relation to film speed, or (in the case of stills) at low shutter speeds. Motion Blur - What is it?Įver tried to take a photo from a moving car or to shoot a fast-moving sporting scene with a camera on low shutter speed? That blurry effect you ended up within the image is motion blur, but for a literal definition let’s turn to the good chaps of the English Oxford dictionary: If you then decide that you are all for the blur or just want to give it a go and test it out, we will also in this post briefly touch upon how to add the motion blur effect to your compositions in After Effects. So which is it? In this blog post, we will let you decide for yourself by giving you the ins and outs & the pros and cons of the motion blur effect in motion design. Then again, according to some motion designers, the best time to use the motion blur effect in motion design projects is: NEVER! Because: FAKE! BAD! From a compositing perspective, motion blur is vital to match special FX elements to live action elements and you can apply the motion blur effect in After Effects to finesse the composition, add realism, exaggerate movement, match shots, make jittery footage easier & smoother to watch and make motion look more natural. There’s a school of thought that motion blur by recreating “realistic” shutter speed can lend a visually pleasing and natural look to motion graphics. Question is, should the simulated motion blur effect be used in motion design? As with everything else in life, there are conflicting views.
