MEMC (Motion Estimation/Motion Compensation) technology is a powerful tool used in video processing to enhance the quality and smoothness of motion in displayed content. It involves interpolating frames between existing ones to create an illusion of higher frame rates and reduce motion blur or judder. This technology, initially developed for and applied to televisions, has gained significant popularity in recent years and is expected to become a prominent trend in the technology market. In this introduction, we will explore the fundamentals of MEMC Motion Compensation Technology, understand its underlying mechanisms, and delve into the reasons why it is forecasted to flourish in the coming years.
MEMC is a typical TV imaging technology, but it’s still relatively new to smartphones. We will learn about MEMC motion compensation technology in this article!
What is MEMC Technology?
MEMC (Motion Estimation/Motion Compensation) stands for motion estimation, motion compensation , smoother video motion , by increasing the number of frames as well as the motion rate between frames by Special algorithm for higher frame rate to bring smooth effect to viewers.
In addition, MEMC also helps to eliminate image noise from unstable signal sources, reducing ghosting and shaking noise for more realistic moving images. MEMC is a featured technology of television and has now also been brought to smartphones.
How does MEMC work?
This technology is capable of calculating movements and compensating them with a special algorithm. MEMC detects motion in a particular frame and tries to estimate what the next frames might look like. Thereby adding the necessary frames, bringing fast-moving frames with super-smooth and smoother high-speed images, minimizing blur.
By using real-time algorithmic adjustments to insert additional frames into the video file, MEMC allows a video recorded at 24fps or 30fps to be played back at 60fps or even 120fps.
How does MEMC work?
Most current movies are shot at the standard 24fps frame rate. If watching with a 60 / 120Hz screen on a TV or on a smartphone, it will not be smooth. To overcome this, MEMC tries to predict what the next frame will look like and adds it between consecutive frames to compensate for incomplete frames .
If there are only 24 frames to display per second, MEMC will add an extra frame after every odd frame and two additional frames after every even frame for a 60Hz display. Because if the number of frames is 60/sec it will be perfect to be viewed on a 60Hz monitor. If the frame rate is higher, say 120Hz, the number of added frames will be modified accordingly.
What are the disadvantages of MEMC?
When shooting a movie, the director wants to shoot a particular scene viewed in the exact way it was shot. And MEMC tries to add in frames that don’t exist at all, so it looks fake, losing detail on the real picture quality of the movie. Due to the fact that the added frameworks lack structure as they are purely based on algorithmic estimation.
The big and only downside of MEMC in phones is that it will reduce battery life . MEMC will not be enabled by default. You will have to go to Settings > Display and enable Motion Graphics Smoothing. When this feature is activated, your phone may consume more battery power because of the video content you are watching.
How is MEMC applied on mobile phones?
OnePlus 8 is not the first phone with MEMC, but before that, there are Black Shark, Black Shark3, and OPPO Find X2 PRO that also have this technology. Before these phones, MediaTek has released a Clear Motion feature that works similar to MEMC chips since 2015, such as the Helio X10 chip.
OnePlus says it has created a custom MEMC chip that can push regular 30fps video to 120fps. The newly launched OnePlus 8 Pro (April 14) owns 120Hz Fluid Display technology with MEMC.
OnePlus introduces MEMC technology on OnePlus 8 Pro
The MEMC used on the OnePlus 8 Pro works the same as it does on a television. The reason that OnePlus decided to include MEMC in their latest smartphone – OnePlus 8 Pro is to want users to experience the 120Hz display to the fullest .
Since most videos and movies are shot at a standard frame rate of 24/30/60fps, while the OnePlus 8 Pro has a refresh rate of up to 120Hz. MEMC technology is applied on OnePlus 8 Pro to increase the number and frame rate to 120fps , so that users can enjoy smoother video viewing on the 120Hz screen.
Which apps support MEMC on OnePlus 8 Pro?
OnePlus has released a list of 7 apps currently using MEMC technology on OnePlus 8 Pro, including: YouTube, Netflix, Hotstar, Prime Video, VLC, MX Player, and the default OnePlus library. OnePlus said that in the future, it will work with more app and game developers.
Should MEMC be a standard feature on all phones?
High refresh rate display is definitely an issue that most manufacturers are aiming for in the near future. Apple is also expected to launch a new line of iPhone 12 smartphones with a 120Hz display similar to the iPad Pro.
Although screen refresh rates are getting higher and higher, the standard frame rate is still 24 fps for movies and 30/60 fps for most other videos. It is therefore recommended to provide the user with a toggle to enable/disable MEMC so that they can decide whether to go with true normal mode or use MEMC.
MEMC is used for smoother motion video images. Phone users will have great experiences from movies, to TV shows, even sports games. Therefore, MEMC will likely become the standard in flagship phones, becomingthe trend of the technology marketin the near future.

In conclusion, MEMC (Motion Estimation, Motion Compensation) is a technology that enhances the display quality of video content by reducing motion blur. By analyzing and predicting motion within each frame, MEMC can accurately generate and insert intermediate frames to smooth out the motion, resulting in a clearer and more seamless viewing experience.
There are several reasons why MEMC is expected to become a trend in the technology market. Firstly, with the proliferation of high-definition content and the increasing popularity of streaming services, consumers now demand better visual quality. MEMC technology meets this demand by significantly improving the clarity of fast-moving scenes, sports events, action movies, and even video games.
Secondly, as the market for large-screen TVs expands, the issue of motion blur becomes more prominent. Traditional LCD panels often struggle to keep up with the fast movements on the screen, leading to blurred images. MEMC technology effectively addresses this concern, ensuring that viewers can enjoy smooth and crisp visuals regardless of the display size.
Furthermore, the rise of augmented reality (AR) and virtual reality (VR) applications further emphasizes the importance of MEMC technology. As these immersive experiences rely heavily on smooth motion rendering, the integration of MEMC in AR/VR devices will enhance the realism and comfort of the user experience, driving its adoption in this rapidly growing market.
Additionally, the advancement and affordability of MEMC technology make it increasingly accessible to consumers. With the integration of MEMC capabilities in a wide range of devices such as TVs, smartphones, tablets, and gaming consoles, individuals can now enjoy the benefits of enhanced motion compensation without the need for expensive dedicated hardware.
In conclusion, MEMC motion compensation technology provides a solution to the persistent issue of motion blur in video content. With its ability to generate and insert intermediate frames, MEMC enhances the viewing experience by reducing blur and creating smoother motion. As consumer demand for improved visual quality grows, and with the expanding market for large-screen TVs, AR/VR devices, and gaming consoles, MEMC is poised to become a prominent trend in the technology market. Its accessibility and affordability further contribute to its market potential, making it a highly sought-after feature in various devices.
