Video Interpolate

Smooth video motion by generating intermediate frames, create 60fps or 120fps from 24fps/30fps video

Drop a video file (short clips work best)

Increase Video Frame Rate Online - Video Frame Interpolation Free

EzyIMG's Video Frame Interpolation tool increases the frame rate of any video by generating new synthetic frames between existing ones. The result is noticeably smoother motion, making it ideal for sports footage, action clips, slow-motion sequences, and older videos recorded at low frame rates. Upload an MP4, WebM, MOV, MKV, or AVI file, choose a target frame rate of 30, 60, or 120fps, and download the interpolated result.

All interpolation runs entirely inside your browser using WebAssembly. Your video is never uploaded to a server. There is no account required, no watermark on the output, and no file size limits enforced by EzyIMG. Because interpolation is computationally intensive, shorter clips (under 30 seconds) are recommended for the best experience.

How to Use

1
Upload your video
Drop an MP4, WebM, MOV, MKV, or AVI file. Short clips under 30 seconds work best.
2
Choose the target frame rate
Select 30fps, 60fps, or 120fps as the output frame rate.
3
Click Interpolate
Click Interpolate to begin. Processing is computationally intensive and may take several minutes for longer clips.

Key Features

→This tool runs entirely in your browser. No upload, no account, and no watermark on the output.
→Input formats: MP4, WebM, MOV, MKV, AVI. Output: MP4.
→Frame interpolation generates new frames between existing ones to create smoother motion. It does not add real detail.
→60fps is the sweet spot for sports and action footage, smoother than 30fps without the artifact risk of 120fps.
→Very high motion scenes may show slight artifacts. 60fps is usually cleaner than 120fps for most content.
→Output files will be larger than the source due to the added frames.

Frequently Asked Questions

Is Video Frame Interpolation on EzyIMG completely free?

Yes, 100% free. No account required, no watermark on the output, and no limits on usage.

Does EzyIMG upload my video?

No. All interpolation runs using WebAssembly (ffmpeg.wasm) directly in your browser. Your video never leaves your device.

What formats does Video Frame Interpolation support?

Input: MP4, WebM, MOV, MKV, AVI. Output: MP4.

Does frame interpolation improve the quality of a low-frame-rate video?

Frame interpolation creates synthetic in-between frames to make motion appear smoother. It does not add real detail but does significantly reduce the choppy appearance of low-fps footage.

What is frame interpolation?

Frame interpolation generates new frames between existing ones using motion estimation, creating smoother-looking video. The frames do not exist in the original. They are synthesized by the algorithm.
