How the conversion works

Frames are resampled down from 24 to 15 fps. 15 doesn't divide 24 evenly, so frames are dropped in a slightly uneven pattern — barely noticeable in most footage. Duration and audio are untouched — only the frame count changes, so nothing drifts out of sync.

Frequently asked questions

Does converting 24 fps to 15 fps lose quality?

You lose the extra frames — that's the point — but each remaining frame is re-encoded at high quality (H.264, CRF 20). Resolution, duration and audio are unchanged.

Does it change the video length or audio?

No. Only the frames-per-second count changes. Duration is identical and audio is carried over in sync.

What formats can I upload, and what do I get back?

Upload mp4, mov, webm, mkv, avi… anything ffmpeg reads. You get back a widely compatible MP4 — H.264 video (CRF 20), AAC audio, web-optimized (faststart).

Is this 24 to 15 fps converter free?

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

Will the lower frame rate reduce file size?

Usually yes — fewer frames per second means fewer frames to encode, so 15 fps files come out smaller than their 24 fps source at the same quality.
