Have you ever been watching TV at a friend or relative’s house, and something seems a bit off with the picture? If your TV’s motion is soft, unnaturally smooth, or even nauseating to look at, it could be due to a feature called “motion smoothing.” While this feature is enabled by default on most new TVs, you can easily disable it for a more traditional cinematic experience. Here’s everything you need to know about what motion smoothing is and how to turn it off on any major TV brand.
Before you can understand what motion smoothing is, it’s important to know a little about frame rates and refresh rates.
Frame Rate vs Refresh Rate
These days, most TVs will have a refresh rate of 60-120Hz (Hertz). That means your TV will refresh the screen 60 to 120 times every second. The problem is most movies and TV shows are only filmed at 24-30 frames per second. So, your TV needs to show the same frames multiple times in a row.
For example, if your TV had a refresh rate of 60Hz, and you were watching content originally filmed at 30fps, your TV would simply show each frame twice. Technically, this will double the frame rate of the video from 30fps to 60fps, so the video’s frame rate (60Hz) would match your TV’s refresh rate (60fps).

When your TV stops on these duplicate frames for too long, it can make moving images look blurry. You’ll be able to notice problems with motion when the camera pans or objects move across the screen quickly.
What Is Motion Smoothing?
Motion smoothing (also known as “image interpolation”) is designed to make motion look sharper by artificially increasing the frame rate of a video to match the refresh rate of your TV. However, this post-processing effect can cause a “soap opera effect” and introduce new visual artifacts to the video.
When enabled, motion smoothing will fill in the gaps between frames. Basically, your TV scans the previous frame and the next frame and guesses what the transitional image should look like. Then, it generates a totally new image and inserts it instead of duplicating frames.
Motion smoothing often smooths things out too much and creates what’s known as the “soap opera effect.” This will change the original feel of your movies, making them look like they were shot on a digital camera rather than film.
Plus, your TV won’t always generate perfect transitional images. While you might not notice any distortion at normal speed, you can see unwanted shadows, halos, flashes, and even dropped frames when the video is slowed down.
Sensitivity to motion smoothing varies from person to person, with some finding the effect hard on the eyes. Many people won’t notice any difference when motion smoothing is enabled, while other viewers might actually enjoy the feature for certain uses, especially sports.
When Should You Use Motion Smoothing?
Filmmakers strongly recommend turning motion smoothing off when you’re watching movies or other content shot at 24fps. However, you might see some benefits from motion smoothing when watching sports, news, reality TV, and other content that was originally shot at 30-60fps.
Ultimately, the decision to turn on motion smoothing comes down to your preferences. It’s a good idea to watch content with motion smoothing enabled and then turn it off to see which one you like better. If you can’t tell the difference, it’s probably best to just turn it off.
How To Turn Off Motion Smoothing on Any TV
Every TV manufacturer uses a different name for motion smoothing, but you can turn the feature off by going into your TV’s settings. Just press the Settings, Home, or Menu button on your remote and look for “TruMotion,” “Auto Motion,” “Action smoothing,” “Motion Enhancement,” or something similar.
Many TVs also have a feature called “Filmmaker Mode,” which you can enable to automatically turn off all post-processing features, including motion smoothing. This feature was introduced in 2019 by directors like Martin Scorsese and Christopher Nolan to help you watch a movie “as it was intended by the filmmaker, preserving the correct aspect ratios, colors and frame rates.”
Alternatively, you can also enable HDR on your TV, which might automatically turn off motion smoothing.
