Frame interpolation method using AI
Whether it's a live-action video or an animation video, each video is made up of individual still images. These still images are called "frames." The number of images (frames) displayed per second is called the "frame rate." If the frame rate is high, the video will look smooth; if the frame rate is low, the video will look choppy.There is a method called "frame interpolation" to convert video recorded at a low frame rate to a high frame rate. Therefore, in this article, we will introduce recommended AI software for frame interpolation.
What is frame interpolation?
Frame interpolation is a technology that creates smooth videos by inserting new frames into videos with a small number of frames.
A system that predicts movement and color changes from previous and subsequent frames and creates new frames to increase the apparent frame rate.
There are two main types of interpolation methods to date: traditional methods and methods using AI
1. Traditional method
Linear interpolation
A method that linearly interpolates parameters such as attributes and positions between the start and end frames.
However, it is not suitable for situations where smooth transitions are required, as it may impair the natural feel of the movement.
Keyframe
A method of selecting specific frames as keyframes and manually creating interpolated frames to smooth the transition between those frames.
This allows for more control, but is generally time consuming and labor intensive.
Optical flow
A method that analyzes pixel movement patterns between adjacent frames to obtain information for generating new frames.
Optical flow is generally effective at generating natural motion, but accuracy can be a challenge in complex scenes.
Intermediate frame generation algorithm
This method uses an algorithm to generate new intermediate frames from existing frames.
This includes geometric transformations, Fourier transforms, texture synthesis, etc.
2. Method using AI
Using deep learning, a model trained from large amounts of video data generates new frames.
This makes it possible to generate smooth animations and videos while preserving complex transitions and details that are difficult to achieve with traditional methods.
However, AI-based methods require high computational resources and are highly dependent on the quality of the training data, so proper training and tuning are important.
While AI-based methods are currently mainstream, traditional methods are still useful in some applications.
Manual interpolation is sometimes required, especially when fine control or artistic expression is desired. The method you choose will depend on your specific goals and constraints.
Frame interpolation software that makes full use of AI
Among frame interpolation methods, frame interpolation software that utilizes AI is one of the most recommended.
This is because the frame interpolation method that utilizes AI has the following advantages.
So easy that anyone can do it! Only 3 steps as shown below
Compared to traditional manual frame interpolation, using AI-based frame interpolation software can significantly reduce the amount of work and time.
AI analyzes video data and automatically generates missing frames to create more natural-looking images.
No specialized knowledge required, high efficiency and better results! I think this is the easiest way to interpolate video frames!
What we would like to introduce here is the standard AI-based frame interpolation software - UniFab Smoother AI. Frame interpolation software UniFab Smoother AI uses AI technology to output videos with fast-moving dynamic scenes as smoother images, increasing the video frame rate to 120fps. UniFab Smoother AI minimizes flickering and shaking in your videos, making them smoother and more natural.
There is a 30-day fully functional free trial, so please download it using the button below and try it out before purchasing.
Also, unlike other frame interpolation software, UniFab Smoother AI has two options. Not only integer frame interpolation, but also frame rate can be selected from 60fps or 120fps. Even when frame interpolation is not performed by an integer multiple, smooth video can be output using AI technology. Additionally, frame interpolation can be previewed in real time.
The paid version of UniFab Smoother AI is a little expensive at 12,500 yen, but it can be used stress-free because it allows high-precision frame interpolation with simple operations. The interface is not cluttered and it is a very easy to use tool. If you are looking for smooth and natural images, please consider UniFab Smoother AI, an AI-based frame interpolation software.
There is also a free trial version, so it would be a good idea to try it out first and get a feel for it. If you are seriously thinking about purchasing it, I think it would be better to purchase the UniFab All-in-One, which includes 9 products such as Smoother AI, Enlarger AI, photo processing AI, and video processing AI, for 37,500 yen.
How to interpolate frames with UniFab
The steps to complete frames with UniFab are as follows:
Launch UniFab, select the "Smoother" module, click "+Video" and select the video file to add.
Then you can adjust frame rate, output quality, audio, etc. Built-in integer multiple frame interpolation.Furthermore, the frame rate can be selected from 60fps or 120fps.
Once the selection is complete, select the save destination and click the "Start" button to start the process.
Now the frame interpolation process can be completed super fast.
Summary
Frame interpolation is a valuable technique in video editing and provides an engaging visual experience. Smooth, natural motion is appealing to viewers, and frame interpolation can maximize that appeal. Utilize frame interpolation technology to create higher quality videos with UniFab Smoother AI, which requires no specialized knowledge, is highly efficient, and has better effects.
