Motion interpolationGenerates real in-between frames instead of duplicating existing ones — visibly smoother when increasing fps. Slower; best for short clips.

How to convert a video to 15 fps

Upload your video. Drop any video into the converter — up to 100 MB, any common format.
Confirm 15 fps. 15 fps is preselected on this page. Pick a different target or type a custom rate if needed.
Choose smoothing mode. Keep motion interpolation on for genuinely smoother motion (slower), or turn it off for a fast frame-duplication convert.
Download. Download the converted MP4. The file stays available for 1 hour, then it's deleted automatically.

When you need 15 fps

Archive screen recordings or security footage compactly

How the conversion works

If your source has fewer frames per second than 15, frames are duplicated — or, with motion interpolation on, real new in-between frames are generated for visibly smoother motion. If it has more, frames are dropped evenly. Duration and audio never change.

Frequently asked questions

What does a 15 fps converter do?

It re-times your video to exactly 15 frames per second by duplicating, interpolating or dropping frames — without changing length, resolution or audio.

Should I enable motion interpolation?

Yes when increasing the frame rate and you want visibly smoother motion — it generates real new frames instead of duplicating. Leave it off when decreasing fps; it has no benefit there.

What formats are supported?

MP4, MOV, WebM, MKV, AVI… anything FFmpeg reads. Output is a widely compatible MP4 — H.264 video (CRF 20), AAC audio, web-optimized (faststart).

Is it free?

Yes — free, no signup, no watermark. Files up to 100 MB, deleted automatically after one hour.
