What is Frame Interpolation | Is it Always Good?

Share on:

In recent years, various modern display devices like projectors, video players and HDTVs, etc. have got a new feature called frame interpolation. The projectors have the capability of determining the differences between the existing and real frames and finally can insert the interim frames to make the video or film more eye-catching. Because of this feature, we can found less amount of motion judder, display flickering, and get a clearer view of film and movie.

So, what is frame interpolation? Well, it is a method to add duplicated frames in-between existing frames, making your videos look smoother to the eye.

What is Frame Interpolation?

Frame interpolation is the feature that artificially increases the frame-rate of the video by creating fake frames in between each frame. It differs from monitor refresh rates. In this video processing system, the intermediate frames between two initial and final frames are generated by the interpolation method. You may have heard about the motion blurry effect in video or games or photography. It is important because it can make animation more fluid, compensation of blur of display motion, and effects of fake slow motion. For laptops and PCs, the ability is often heavily dependent on the graphics card you have, preferably a dedicated one.

Limitations of Frame Interpolation

There are two complaints about this. One is its making digital video effects on video or films sometimes which is sometimes called the soap opera effect. Because of this problem, your face can look like another person’s face.

And the second one is another problem. Interpolation can reduce the motion judder but at the same time, some other effects are found on the videos or films like ghosting like some abnormal or unusual subjects’ movement.

These two problems sometimes arise not all the time because of the structural differences in the video players. But when it works properly, the picture will be free from artifacts that actually keep the good quality.

Where the Frame Interpolation is Used

There is a misconception about interpolation seeing it in a particular video system. You should not take a single interpolation demo for granted that it will look the same on all video systems. Because different vendors apply different algorithms to generate interim frames. That is why the frame interpolation varies from product to product. And you keep this in mind when you will approach video systems.

Some people do not want digital video effects in traditional movie viewing. Some projectors with frame interpolation may provide this digital video effect and people do not appreciate this. When interpolation suited with digital video effects, then the projectors can be easily used for animated movies. There are also some projectors which do not provide digital video effect with frame interpolation.

If you watch sports on an HD channel broadcasting 1080i, then frame interpolation will help you to get the most realistic effect. There is some HD music video concert disc which is enhanced by interpolation.

If your video systems like projectors provide exaggerate digital video effects because of frame interpolation, you can use them for HD sports, animated movies, and music concerts, etc. There should be an option of no using frame interpolation so that you can use it according to your need.

Where the camera’s span is quite slow, there will be quite less amount of motion judder. And there will not need frame interpolation as motion judder is absent there. Movies or videos with motion judder will be perfect for frame interpolation. So you can try this one when you find of motion judder problem in your video. So try this one when you find the requirements.

Frequently Asked Questions and Answers

Should I use frame interpolation?

When used in different types of video source materials, frame interpolation brings great success. Although not every time, but sometimes it helps enormously.

What is an example of frame interpolation?

A great example of frame interpolation is to turn 30fps videos into 60fps using AI.

Is 30fps good for cinematic?

The universally accepted norm for cinematic is 24 fps. In North America, the accepted broadcast frame rate is 30 fps. But in Europe it is 24 fps.


Its, been out a few years now and more recently frame interpolation got much more improved too, due to the implementation of the Artificial Intelligence. We recommend you trying it out to see if you like the results or not. For most videos shot on a low fps, frame interpolation can be a game changer.
