Video Interpolate

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

Free Video Frame Interpolation — Convert to 60fps or 120fps Online

ezyimg's Video Interpolate tool generates intermediate frames to create smoother motion at 30, 48, 60 or 120 fps. Uses the minterpolate filter in ffmpeg for motion-compensated interpolation. Best for sports, slow motion, and animation. All in your browser.

How to Use

  1. 1

    Upload a short video

    Drop an MP4, WebM, or MOV file. Keep it under 30 seconds for reasonable processing time.

  2. 2

    Choose target FPS

    30fps for standard smooth, 60fps for very smooth motion, 120fps for ultra-smooth.

  3. 3

    Interpolate and download

    Processing takes 2–10 minutes for short clips. The result is a smoother video at the selected frame rate.

Tips & Best Practices

  • →60fps is the sweet spot — very smooth without excessive file size.
  • →Videos with simple motion (talking heads, slow pans) benefit most from interpolation.
  • →Fast action with complex motion may show artifacts — use 60fps instead of 120fps.
  • →Keep source clips under 30 seconds to avoid browser memory limits.

Frequently Asked Questions

How do I convert 24fps video to 60fps online?

Upload your video to ezyimg's Video Interpolate tool, select 60fps, and click Interpolate. The tool generates new intermediate frames to smooth the motion.

What is frame interpolation?

Frame interpolation generates new frames between existing ones using motion estimation, creating smoother-looking video. The frames don't exist in the original — they are synthesized by the algorithm.
