Thanks to AI technology, frame interpolation which is typically useful for videography is revived to help generate smooth transitions between your video frames. Frame interpolation software simplifies the process of synthesizing non-existent intermediate frames in a video sequence to provide a smooth and consistent visual experience. For example, you can convert a blurry 24fps/30fps video to high-quality 60fps; or you can create a slow-motion video @120fps, 240fps or higher.

After tried-and-true tests, we have selected the top 6 tailor-made AI frame interpolation software tools to help you boost video FPS or create slow-motion videos.

Part 1. What Is AI Frame Interpolation?

As we have mentioned at the very beginning, AI frame interpolation is the process of automatically creating and inserting new images between adjacent video frames. Once there are more frames in one second, the picture will be smoother and clearer. For example, if you convert 30fps to 60fps, your image looks higher in quality and smoother in motion. That’s because more frames will give more details.

15FPS vs 30FPS vs 60FPS

AI frame interpolation is mainly used to improve the smoothness of a video. So, you can smooth animation, restore old movies, and improve video FPS to match the smart TV with high Hz. Also, you can make slow-motion videos easily and create a video with image sequences. With AI video frame interpolation software, all of those can be realized as easily as ABC.

Part 2. Top 6 AI Frame Interpolation Software

No.1: Winxvideo AI

* An AI-powered video & image enhancer with a frame interpolation function for frame rate conversion.

Winxvideo AI is innovative and newly-released multifunctional software from Digiarty for users to enhance video quality, deshake and stabilize videos, upscale image quality, convert video formats, record screens, etc. If you use its AI frame interpolation function, you can set the video frame rate by 2X, 3X, 4X, and 5X in a click. For example, Winxvideo AI will automatically convert a 30fps video to 60fps, 90fps, 120fps, or 150fps once you have chosen the desired FPS.

With the help of the built-in advanced AI frame interpolation algorithms, this frame interpolation software also allows you to detect and stop interpolating between scene changes to avoid artifacts. This helps interpolate what should be interpolated automatically, and you can take your eyes off the screen.

No.2: Topaz Video AI

* An overall AI video enhancer using neural networks for video upscaling, motion interpolation, and shake stabilization.

After five years of crafting robust AI models for natural results on real-world footage, TopazLabs released the AI-powered video enhancer – Topaz Video AI to help upscale the video resolution to 4K or even 8K; and improve the video quality. Topaz Video AI has been trained with hundreds of video clips, so it performs better than most of the video upscaling software in the market.

Back to its motion interpolation function, Topaz Video AI utilizes the RIFE frame interpolation algorithm that uses convolutional neural networks and deep machine learning to learn, create, and interpolate video frames. It does well in converting videos to 4K@60fps and even 120fps to offer you a buttery smooth viewing experience. Compared to some rivals, Topaz Video AI has fewer motion artifacts like shimmering or flickering, and can create better slow-motion videos.

As professional AI frame interpolation software, Topaz Video AI has designed 4 unique modes to help interpolate videos, including Chronos, Chronos Fast, Apollo, and Apollo Fast. Chronos is recommended for slow motion beyond 8x, or smaller than 4x, or FPS conversion. Chronos Fast specializes in fast motion with larger changes between frames. Apollo is used when you need exactly 2x, 4x, or 8x frame count multiple. Apollo Fast is recommended for use for any non-double conversions, e.g. 24fps to 29.97 or 60; and also for use when speed is a factor and you require exactly 2x or 4x frames.

All in all, Topaz Video AI is a multifunctional tool you can use to enhance, interpolate, stabilize, and deblur videos. You can feel free to use it to remove video noises, recover low-quality videos, restore old movies, smooth animation, and create 60fps/120fps slow-motion videos.

Part 3. How to Interpolate Videos with Frame Interpolation Software?

To perform video interpolation, one must utilize video frame interpolation software. Currently, there exist three primary categories of video frame interpolation tools: frame interpolation-only software, online tools, and video processing software. Each category possesses its own set of advantages and disadvantages. In this instance, we will utilize Winxvideo AI as an illustration to demonstrate the process of video interpolation.

Winxvideo AI, an advanced video and image enhancer, utilizes artificial intelligence to provide an exceptional frame interpolation feature. This cutting-edge tool enables users to effortlessly transform videos into high frame rates such as 60fps, 120fps, 240fps, and 480fps. Additionally, it excels in enhancing animations, revitalizing old movies, and offers a plethora of other remarkable functionalities.

Video AI UI

Step 3. Drag and drop a video you want to interpolate frames. Winxvideo AI lets you process more than one video at the same time, including video enhancement, frame interpolation, and video stabilization.

Step 4. On the right part, check the box of "Frame Interpolation", and you can start frame interpolating your video to 60fps, 120fps, 240fps, and even 480fps. Just choose from 2X, 3X, 4X, and 5X to double, triple, quadruple, quintuple the video frame rate.

Set FPS

Tips:

  • To achieve the desired frame rate, one can repeat the process multiple times to reach the target frame rate. For instance, selecting 2X twice can convert a 30fps video to 60fps and subsequently to 120fps. This approach yields superior output quality compared to directly choosing 4X.
  • Check Skip Scene Changes or not: Whether to always compare the difference between two frames and not insert the frame if the difference is too large.
  • Create slow-motion video by choosing 2X, 3X, 4X, or 5X to slow down the playback speed. For example, you can create a slow-motion video about the passing through an egg, a water glass, a watermelon, etc.
