Overview

The Video Frame Interpolation tool allows you to convert videos to higher frame rates, such as 30fps, 60fps, or custom values, to achieve smoother motion. By utilizing motion-compensated interpolation, blending, or frame duplication, this tool processes your uploaded video file and outputs a high-frame-rate version in your preferred format while preserving or removing the audio track.

When to use

When you need to convert low-frame-rate footage, like 24fps cinema video, into smooth 60fps or 120fps playback.
When preparing gameplay recordings or sports clips where high-speed motion benefits from extra generated frames.
When standardizing video assets to a uniform frame rate for editing or broadcasting requirements.

How it works

1Upload your source video file (up to 100MB) in a supported video format.
2Select your target frame rate, choosing from standard presets like 60fps or entering a custom value between 10 and 240.
3Choose the interpolation mode, such as Motion Compensated for high quality, Blend for faster processing, or Duplicate for simple frame copying.
4Configure output settings like file format and audio preservation, then start the processing to generate the smoother video.

Use cases

Smoothing out choppy 24fps drone footage to 60fps for a more cinematic and fluid look.
Converting 30fps screen recordings of software tutorials to 60fps to make cursor movements look seamless.
Creating high-frame-rate slow-motion source files by interpolating standard footage before slowing it down in editing software.

Examples

1. Smoothing Action Camera Footage

Action Sports Videographer

Background

An outdoor videographer captured a mountain biking run at 30fps, but the fast-moving trees and ground look jittery.

Problem

The footage needs to be converted to 60fps using motion estimation to make the high-speed descent look fluid.

How to use

Upload the raw MP4 video, set the Target Frame Rate to 60 fps, choose Motion Compensated (Best Quality) as the interpolation mode, keep the audio enabled, and select MP4 as the output format.

Target Frame Rate: 60, Interpolation Mode: mci, Output Format: mp4, Keep Audio: true

Outcome

The output video plays back at a smooth 60fps with newly generated intermediate frames that eliminate the jittery motion.

2. Preparing Gameplay Clips for Social Media

Gaming Content Creator

Background

A streamer recorded gameplay at 30fps but wants to upload a high-quality 60fps short to YouTube.

Problem

The creator wants to quickly upscale the frame rate without losing audio sync.

How to use

Upload the gameplay clip, select 60 fps from the target frame rate dropdown, choose the Blend mode for faster processing, and set the output format to WebM.

FAQ

What is the difference between the interpolation modes?

Motion Compensated (mci) calculates new frames based on movement for the best quality, Blend mixes adjacent frames, and Duplicate simply copies existing frames.

Can I set a custom frame rate outside the standard presets?

Yes, select 'Custom FPS' and enter any value between 10 and 240 in the custom frame rate field.

Will the output video include the original audio?

Yes, if you keep the 'Keep Audio' option checked, the original audio track will be preserved in the output file.

What video formats are supported for the output?

You can export your interpolated video as MP4, WebM, MKV, AVI, or MOV.

Why does the interpolation process take several minutes?

Motion-compensated interpolation requires intensive pixel-by-pixel motion estimation for every generated frame, which is computationally demanding.
