AI Frame Interpolation Can Convert Videos to 60fps

AI Interpolation is a unique and powerful method to upscale frames in any video without worrying about image ghosting, stutter, and distortion. Many tools and platforms use this technology as it is proven to be much more reliable than the conventional methods. Thanks to artificial intelligence, these tools easily analyze the background, foreground, and other elements in the video to naturally upscale it without any visible artefacts at all. Now that people go after quality in every content they consume, such tools can vastly benefit in interpolating frames without having to struggle for hours.

AI Interpolation VS Conventional Frame Interpolation

How Does AI Interpolation Work?

AI Interpolation uses machine learning models and precisely understands the video's motion to add pixels accordingly. With the help of AI, these models can smartly distinguish between background and foreground elements which helps in a logical reconstruction of the video. A realistic reconstruction of the video is achieved by giving the tool up to ten neighboring frames immediately surrounding the Interpolated frame instead of just two. Using these images, it can predict what the missing elements look like and fill it in when it becomes visible. This process helps to tackle many problems like image ghosting, distortion, and stutter.

What is Frame Averaging?

Frame Averaging is the most basic Interpolation method and works by overlaying two neighbouring frames on top of each other. This technique may be easy to implement but not worth it to use on every footage. If a video has either too much or too less motion, the results will look unnatural. Slightly blurry Interpolated frames are formed when frame averaging is used on videos without much motion. On the other hand, videos with more motion will suffer from ghost frames, artefacts, and blurriness. This conventional method is perhaps not the most useful when your target is to create smooth footage.

What is Motion Estimation?

Motion Estimation is a sophisticated frame Interpolation method that works by breaking up the frame into a collection of blocks and estimating their movement between frames. This algorithm generally uses dynamically sized blocks that change depending on the difference between two frames, rather than smaller and fewer blocks. Using fewer blocks might speed up the process but can distort detailed movements. A velocity vector is calculated for each block after dividing a frame. The velocity represents the movement of a block between two frames and thus, the frames in between can be constructed by distorting the image, so the cells move to their next location.

Is AI Interpolation better than Conventional Frame Interpolation?

AI Interpolation is better than conventional methods like frame averaging and motion estimation. You must put in very little effort in AI Interpolation and at the same time, you can get the best results using this technique. Frame averaging is also a simple overlaying method, but it cannot produce good results, especially in videos with no motion or too much motion. Motion estimation is a sophisticated method, but it does produce decent results. However, it requires a lot of human effort, and it still lags when it comes to dealing with complex movements in a video. Therefore, AI Interpolation is the best possible way to smartly enhance your videos.

Top 4 AI Interpolation Tools for 60 FPS Videos

1. Myungsub CAIN

CAIN (Channel Attention for frame INterpolation) is a novel framework for video interpolation that synthesizes high-quality images without explicit estimation of motion. It incorporates channel attention with PixelShuffle to effectively generalize to unseen motions. Most existing methods use bidirectional optical flow or its variants for motion estimation, but CAIN uses a deep neural network architecture for accurate video frame interpolation. It performs video frame interpolation using spatially adaptive convolution filters whose weights are predicted by a convolutional neural network (CNN). The conventional video frame interpolation techniques demand a precise optical flow estimation and require additional model complexity resulting in a high computational cost. CAIN, however, uses an effective deep neural network which is end-to-end trainable and free from a motion estimation network component. Thus, it requires less computational cost and performs even better.
