Convert Video to 60 FPS Online

Converting a video to 60 frames per second is one of the most effective ways to make it look smoother on today's screens. Most monitors, laptops and phones refresh at least 60 times a second, yet a great deal of footage is recorded at 24, 25 or 30 FPS. SmoothMotion.video uses motion-compensated frame interpolation to fill the gaps, generating real in-between frames rather than repeating old ones, so pans, movement and scrolling look fluid. It is free, runs online and needs no account.

Why "changing the frame rate" usually doesn't help

If you change a 30 FPS video to 60 FPS in a typical editor or converter, the program usually just shows every frame twice. The file now says 60 FPS, but the motion is identical to the original: there is still only 30 distinct pictures per second. Some tools offer "frame blending" instead, which averages neighbouring frames and gives a soft, double-exposed look on anything that moves quickly.

To make motion look genuinely smoother, the new frames must show objects at intermediate positions. That requires working out where everything moved and drawing it part of the way there – which is exactly what motion interpolation does.

How to convert a video to 60 FPS

1. Upload your file using the tool above. MP4, MOV, MKV, AVI, WebM and M4V files are supported, up to 500 MB, 5 minutes long and 1920×1080.
2. Leave the output set to 60 FPS. It is the default.
3. Start processing. Your file is checked to confirm it contains a valid video stream, placed in a queue and processed in the background. A progress bar and a periodically refreshed thumbnail taken from the interpolated output let you follow along.
4. Preview the result directly in your browser.
5. Download the MP4. The file is named after your original, for example clip_smoothmotion_60fps.mp4.

Your video keeps its original resolution and audio, and plays at exactly the same speed. Media is deleted automatically 30 minutes after processing finishes, so download your result promptly.

What happens to different source frame rates

The number of new frames depends on what you start with:

When the source rate does not divide evenly into 60 (as with 24 or 25 FPS), the interpolator calculates each output frame at its exact point in time. That avoids the uneven judder you get from simple frame repetition, known as pulldown. Converting 30 FPS to 60 FPS is the simplest case, because every new frame sits exactly halfway between two originals.

If the source is already 60 FPS, there is nothing for interpolation to add at this setting – consider whether 120 FPS makes sense for your display instead.

Footage that benefits most from 60 FPS

• Phone videos shot at 30 FPS, especially those with panning or walking shots.
• Screen recordings and tutorials where scrolling text and moving windows look jerky at low frame rates.
• Gameplay clips captured at 30 FPS that you want to look closer to how the game felt to play.
• Sports and action where following a ball or player benefits from more motion samples.
• Drone and gimbal footage with smooth, steady camera movement – an ideal case for interpolation.

Footage that is harder to improve includes very fast, chaotic action, shots with lots of overlapping objects, and animation with held frames. For a broader look at why videos stutter, see our guide to making choppy video smoother.

Is 60 FPS right for your video?

60 FPS is the safest choice for most viewers because it matches the refresh rate of the majority of displays and is widely supported for online playback. But it changes the character of footage. Film-style content shot at 24 FPS can start to look like live TV – often called the soap-opera effect. If you are unsure, our 30 FPS vs 60 FPS comparison explains the trade-offs in more depth.

Getting the best results

• Start with the best source you have. Interpolation works from what is in the frames. Heavy compression, blockiness or noise makes motion harder to track and can introduce artifacts.
• Trim before uploading. A shorter clip processes faster and keeps you well within the 5-minute limit.
• Avoid already-duplicated frames. If a clip was previously converted by repeating frames, interpolation may produce uneven motion. Use the original recording where possible.
• Check the preview thumbnail. It comes from the actual interpolated output, so if something looks wrong early on you can cancel the job and try a different clip; cancelling deletes the media immediately.
• Be patient with 1080p. Motion-compensated interpolation is CPU-intensive and can take longer than the video's running time.

What you get

The output is an MP4 file with H.264 video and AAC audio, using the widely compatible yuv420p pixel format and faststart, so it plays in browsers, on phones and in video editors, and starts streaming quickly. Because the frame rate is genuinely 60 FPS, you can drop it into an editor timeline set to 60 FPS without further conversion.
