To disable motion smoothing on a Roku TV



  TCL Roku TV Interface

Roku TVs sometimes use a technique they call "Action Smoothing" to artificially increase the speed of the video clip, but it often stops looking fake and destroying the movie's movie.

What Is "Action Smoothing" Anyway?

Action smoothing is Roku's motion smoothing implementation, a common feature on advanced televisions. Movement equalization works by increasing the video clip's forwardness on the TV. More frames make the motion feel softer, but there is a problem: since there is no way to create new frames out of nowhere, it must take two frames and try to figure out what the "intermediate frame" is. This leads to many motionless frames and a fair number of artifacts.

Roku says "Action Smoothing" reduces "motion blur", which is true as far as it goes. It can help you see quick moving objects more easily, but it adds some motion blur between the images to make them softer. It can be good for fast live events such as sports, but it can make movies and TV shows look strange

This feature is not included on all Roku TVs. We couldn't find it on any of our TCL Roku TVs, but some manufacturers included it.

How to Disable Action Smoothing

Fortunately, you can disable this feature on your Roku TV. Roku hides the option under "Advanced Picture Settings" in the menu, which you can open by pressing the "*" button below the directional panel of the remote control. Note that how this button works is changed depending on what is on the screen. It does not work on the Roku website or on the web pages for streaming video apps, all of which use the "*" button for other things. You must play a video in a streaming app to get to the menu. You can also access the menu by simply pressing "*" when you have selected a specific HDMI or other input on your TV. No need to play a video then.

If your Roku has motion smoothing, you will see "Smoothing Actions" under Advanced Image Settings. There are four different levels of action equalization you can choose: High, Medium, Low and Off. If you just want to get rid of the motion smoothing effect, select "Off". The other levels will use less motion smoothing, but will still interpolate the content. (If you do not see the Smoothing options, your Roku TV has no motion smoothing.)

Your Roku TV will save your settings, but it has different settings for different content types. Here's how Roku says:

Settings for smoothing actions are unique and persistent for each input and for each type of content (eg 1

080p, 4K, 4K HDR). For example, if you have a 4K Blu-ray ™ player connected to HDMI 1, you can assign another setting equalization for 1080p movies, 4K movies, and 4K HDR movies. Each time you return to HDMI 1 to watch a movie, the Equalization Action setting is automatically reset to the assigned value depending on the type of content being viewed.
