What Is Video Interpolation, and Why Is It Important?

Video interpolation involves inserting additional images between existing video frames to eliminate blur and fill visual gaps, creating fluid motion. More frames per second (FPS) can make any video come alive, providing an exceptional viewing experience.

15 to 30 fps video interpolation

For instance, low-frame-rate videos can appear choppy or blurry, primarily when displaying fast-action sequences like motocross jumping or fast-moving objects like tennis balls. Turning them into high-FPS footage gives them a smoother, more elegant appearance.

The same goes for fast-paced action in video games. Frame interpolation removes motion blur, introducing more clarity for realistic, visually appealing high-speed movements.

Besides achieving smooth video playback, frame interpolation can help you create slow-motion videos to emphasize details or add a dramatic touch. You can also upgrade old footage like documentaries or family archives, removing flickering issues and giving them a polished look.

Are you ready to transform your videos with online frame interpolation tools? Check out our top picks.

Challenges of Online Video Interpolation and Why a Desktop Tool is the Better Choice

Online video interpolation tools provide fast results without requiring software installation. However, those results can’t come close to their desktop counterparts.

Why? Because they typically have fewer functionalities. For instance, you can’t choose a video interpolation type like frame sampling, frame blending, or optical flow. That leaves default settings, which sometimes don’t meet user expectations.

Other limitations include poor-quality hard-coded algorithms to interpolate videos. Only some online platforms offer AI-powered tools with advanced algorithms. However, they don’t let you select a model either to control the process and achieve the desired results. Some may even introduce unwanted artifacts, lowering video quality.

Desktop software may require more computing power, but you can enjoy higher-quality videos. The best part? You can get an affordable solution with cutting-edge editing features. Here’s one excellent example.

Enhanced Video Interpolation on Desktop With Wondershare Filmora

Wondershare Filmora is the best option for editing videos, including interpolating frames. It lets you choose a video interpolation model (frame sampling, frame blending, or optical flow) and change video speed to make slow-motion or time-lapse videos.

Why is it better than online tools? Because it uses proprietary AI technology to optimize the process. It enhances visual smoothness without quality loss and boosts the frame interpolation efficiency. You don’t have to worry about unwanted artifacts or waiting forever to interpolate frames.

Furthermore, you can resize your video before or after AI frame interpolation and export it in a preferred format. Online tools limit you to the original format.

Unlike online tools, it doesn’t limit exported video length and resolution for non-subscribers, making it a no-brainer in the desktop vs. online video interpolation battle. Filmora can also stabilize shaky footage, remove silent fragments, reframe videos for social media, etc. It uses state-of-the-art AI algorithms and can even generate music and videos from text prompts and recommend edits (you’ll love the AI Copilot).
