Why Use Frame Interpolation?

Low frame rate video can look choppy, especially in fast motion or when viewed on high-refresh displays. Frame interpolation increases the number of frames per second by generating in-between frames, making motion appear smoother. Use it for gaming clips, sports, or any video where you want a more fluid look—without uploading files or installing software.

Tool Features

  • Target FPS 30–120: Choose the output frame rate; higher values give smoother motion
  • Two methods: Blend (smoother in-between frames) or FPS (faster conversion)
  • Output formats: Export as MP4 (H.264), WebM (VP9), or MOV (H.264)
  • Preview: Watch your source video before processing
  • Re-apply: Change FPS or format and run again without re-uploading
  • Privacy: All processing happens in your browser; videos never leave your device

Benefits

  • Smoother playback: Higher FPS reduces stutter and improves perceived quality
  • Flexible output: MP4, WebM, or MOV for any platform or workflow
  • No install: Works in the browser; no software to download
  • Re-apply: Try different FPS or format without re-uploading

How Frame Interpolation Works

Add your video, then set the target FPS (30–120) and choose the interpolation method: blend for smoother motion (when supported) or FPS for faster processing. Pick your output format (MP4, WebM, or MOV) and click Interpolate. The tool processes the video in your browser, generating additional frames to reach the chosen frame rate. You can preview the result, download it, or re-apply with different settings. All processing stays on your device.

Frequently Asked Questions

What is video frame interpolation?

Frame interpolation increases the frame rate of a video by generating new frames between existing ones. For example, a 30 fps video can be converted to 60 or 120 fps for smoother motion. The tool uses blend-based interpolation when available, or a faster FPS conversion method.

What FPS can I choose?

You can set a target FPS between 30 and 120. Higher values (e.g. 60 or 120) produce smoother motion but take longer to process. Choose based on your needs and device performance.

What is the difference between blend and FPS method?

Blend creates smoother in-between frames by blending adjacent frames, often giving a more natural result. The FPS method is faster and duplicates or resamples frames; motion may look less smooth but processing is quicker.

What output formats are available?

You can export as MP4 (wide compatibility, H.264), WebM (web-optimized, VP9), or MOV (Apple-friendly, H.264). Choose the format before running interpolation.

What video formats are supported as input?

Common formats such as MP4, MOV, WebM, MKV, AVI, and more are supported as input. Output can be MP4, WebM, or MOV. Processing happens in your browser.

Is my video data secure?

Yes. All processing runs in your browser. Your video never leaves your device and is not uploaded to any server. No data is stored or transmitted.

Can I change FPS or format after exporting?

Yes. After a successful export, use Re-apply to run interpolation again with a different target FPS, method, or output format. No need to re-upload the video.

Why does processing take a while?

Frame interpolation re-encodes the video and may generate many additional frames. Longer or higher-resolution videos take more time. Processing may take from a few seconds to several minutes depending on length, target FPS, and your device.
