TV Motion Rate Explained

Motion Interpolation Overview

You may want to check out my article on how LCD TVs work to better understand what will be talked about here. Moving on, even with new hardware technologies being released, sometimes they can only do so much to over come their natural disadvantages. This is where motion interpolation comes into play.

By implementing new and better software inside the TV we can help the new hardware that is being released. This is done by increasing the frame rate or frames-per-second of the scenes that are being viewed. Most commonly 30 FPS is boosted to 60 FPS and 60 FPS is boosted to 100 FPS. This makes for a smoother picture that most will find enjoyable. Though, if too smooth it may become “too real” and be very annoying to watch. A little bit of a pick-your-poison situation.

What it is: Increased frame rate over the native frame rate.
Why it matters: Smoother scenes when watching a program.
When it matters: The look of a smoother video. Also known as the “Soap Opera Effect”.

Also, note that motion interpolation is not simply measured, but is more of a yes and no. Either a TV has the options or it does not.

Interpolation Definition and Understanding

Definition – the insertion of something of a different nature into something else.

With the above definition is it easy to understand what it being done behind the scenes to help better the scenes on a TV. Below is a scene without motion interpolation and a scene with interpolation.

With Motion Interpolation

Clear as day. With more information being fed to the TV, it is able to produce a more clear and smooth image of what was originally captured. This is especially important for any one that wants any kind of content to look smoother than it already does. Though, be careful as it can be a powerful effect. Resulting in a scene that is far too different than its original source.

Visual artifacts are a known side effect of an interpolation that is too powerful.

Different Motion Interpolation Names

As marketing a new feature becomes more and more necessary, different manufacturers need to find an edge. Listed below are different names given to the same technology by different manufactures.

Manufacturers Method Name
Hitachi Reel120
Insignia DCM Plus, Insignia Motion 120 Hz
LG TruMotion
AOC Motion Boost 120 Hz
Bose VideoWave III
Mitsubishi Smooth 120 Hz
Panasonic Intelligent Frame Creation
Philips HD Digital Natural Motion, Perfect Motion Rate
Samsung Auto Motion Plus
Sharp Fine Motion Enhanced, AquoMotion Base/Pro
Sony MotionFlow
Toshiba ClearScan 120 Hz, 240 Hz
Vizio SmoothMotion
Sceptre EMC (Motion Estimation/Motion Compensation)
Hisense Ultra Smooth Motion Rate SMR 120


Motion interpolation is a great effect and a handy little feature to help smooth some crazy scenes that are just too hard to see everything in. Though, be careful as the effects can be too powerful. A scene that looks nothing like the source can be annoying and once changed some times hard to fix the settings. Overall, it’s fun and handy for the average user and detailed people out there.
I hope this helps iron out some of the kinks with motion interpolation.
