Motion smoothing builds an entirely new frame in between the two existing frames that acts as a bridge to connect them. When an object in one frame is in a different location in the next frame, we have motion. The content that you see on your TV can actually be broken down into a series of individual static images - what we call frames. How does motion processing work and how can it be fixed? TechRadar spoke to Richard Miller (EVP of Technology) and Miguel Casillas (Senior Director of Ecosystem Marketing) who work at Pixelworks, the company behind TrueCut Motion, who explained how this technology could revolutionize motion processing and how it can be used to fix films. That’s the idea behind TrueCut Motion, a new format that will soon be available on some TCL TVs. ![]() Any such non-standard branding indicates a different term for motion rate, and not the actual refresh rate (per Tom's Guide).It turns out there’s a way for content to be mastered, delivered and displayed in a way that circumvents interpolation. Make sure the refresh rate figure isn't clubbed together with any of these words: Motion Rate, TruMotion, Motionflow XR, X-Motion Clarity, Natural Motion, Clear Motion Index (CMI), Clear Action, or Dynamic Motion Rate. You should also watch out for manufacturer branding around the refresh rate figure. Make sure that the refresh rate specification doesn't say that the refresh rate is with MEMC, since that would mean that it is not the actual refresh rate but instead the motion rate. That's the only number you should look at, especially if you're trying to buy a TV that has a higher hardware-supported refresh rate. Look for the refresh rate listed under the specifications. The universal advice here would be to always look for the specification, which says "refresh rate." Regardless of whether you're buying a TV in-store, online, or already have a TV, you can check the model number online and find the full specifications on the manufacturer's website. ![]() So even if you're getting a 400fps figure in your game, you'll only see 60fps if your monitor or TV supports a 60Hz refresh rate, even if the motion rate promised by the manufacturer is 480Hz. So if you want to play a 120fps clip on a 60Hz TV, or play a game running at 300fps on a 120Hz TV, you won't actually see output above the native refresh rate of the TV (60Hz/120Hz). While motion rate promises a smoother picture, it can't quite display a higher frame rate as-is. Knowing this is crucial to understand the confusing jargon manufacturers use to denote motion rate (via DisplayNinja).Īs explained earlier, frame rate also plays a crucial part here. However, the TV will still be actually 60Hz or 120Hz, and the motion rate won't quite change that hardware limitation. Motion rate promises to take 60Hz displays to 120Hz, or even 240Hz and 480Hz, and 120Hz displays to 240Hz, 480Hz, and even 960Hz. However, the motion rate still often gives a fake soap opera effect when enabled, so it's not equivalent to having a proper high refresh rate TV. Motion rate implementations aim to give you more than what the hardware is capable of. BFI is generally used to get a smoother motion output without the typical motion smoothing effect. Black frame insertion works by inserting a black frame between two frames, either by rapidly turning the backlight on and off, or in the case of OLED displays, rapidly turning the screen on and off, as How-To Geek explains. This results in a smooth motion, which gives it a high-refresh-rate look, but may bring in additional display artifacts which defeat the purpose.īlack Frame Insertion - This is used to counter motion blur, often in scenarios where motion smoothing is in progress. Some implementations may also use AI to generate the next frame. As this IEEE paper on MEMC explains, it calculates the motion trajectory and adds a frame before the next frame appears, acting like an artificial bridge between the two frames. MEMC works by estimating motion by looking at the motion vectors and the direction in which objects are moving. This is a common motion interpolation technology when it comes to motion smoothing implementations in TVs. MEMC - Short for motion estimation and motion compensation. ![]()
