Convert 48 fps video to 30 fps online. 30 fps is the NTSC and web standard used by most phones and social platforms. Frames are resampled evenly; duration, audio and sync stay exactly as they were.
Frames are resampled down from 48 to 30 fps. 30 doesn't divide 48 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.
| Method | Even frame resampling (drops extra frames) |
|---|---|
| Output | MP4 — H.264 video (CRF 20), AAC audio, web-optimized (faststart) |
| Duration & audio | Unchanged, stays in sync |
| Input formats | MP4, MOV, WebM, MKV, AVI… anything FFmpeg reads |
| Privacy | Processed on our server, auto-deleted after 1 hour, never shared |
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.
No. Only the frames-per-second count changes. Duration is identical and audio is carried over in sync.
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).

Usually yes — fewer frames per second means fewer frames to encode, so 30 fps files come out smaller than their 48 fps source at the same quality.
