Convert video frame rate: 24fps (cinematic), 30fps (standard), 60fps (smooth gaming), 120fps (slow motion). Use-case presets for film, YouTube, gaming, and smooth motion interpolation.
Different platforms and devices expect different frame rates. The Frame Rate Converter changes a video's FPS, from cinema-standard 24fps to smooth 60fps, or any custom value up to 240. It works by resampling the existing frames to the target rate: when you raise the rate it duplicates frames to fill the gaps, and when you lower it, it drops frames evenly. The video stream is then re-encoded so the new rate is baked in.

Convert videos between MP4, WebM, OGG, MOV, AVI, and MKV formats. Device presets for YouTube, Instagram, TikTok, iPhone, Android. Quality options from fast to high quality encoding.
Trim and cut videos precisely with frame-by-frame scrubbing. Set start/end points visually, preview clips in real-time, and export trimmed videos instantly. No upload required - runs 100% in browser.
Merge multiple video clips into one seamless video. Drag-and-drop reordering, preview before export, timeline visualization. Combine videos in any format with automatic re-encoding.
A 60 fps capture must be 30 fps to match the rest of an edit timeline.
Input
capture.mp4 60 fps → 30 fps
Output
A 30 fps file with even frame decimation, no judder
Converting between related rates by clean decimation (or interpolation when going up) avoids the stutter an uneven cadence causes when mixed with other footage. Matching fps across clips keeps motion uniform in the final edit.

Convert between 24fps, 25fps (PAL), and 30fps (NTSC) to meet broadcast or distribution requirements.
Normalize clips recorded at different frame rates to one common rate before merging or uploading them together.
Lower the frame rate of screen recordings or surveillance footage where high FPS is unnecessary, significantly reducing file size.
Relabel and re-encode console captures to a target frame rate for consistent YouTube or Twitch uploads.
Changing frame rate is not as simple as relabeling the FPS metadata. This tool uses FFmpeg's fps filter to resample the timeline to your chosen rate, then re-encodes the video with H.264 (ultrafast preset, CRF 23) while copying the original audio track unchanged. Going to a higher rate duplicates existing frames so the file genuinely plays at the new FPS, the motion does not look smoother because no new in-between frames are invented, the same captured frames are simply shown more often. Going to a lower rate drops frames at even intervals, which reduces file size and is virtually invisible on static or slow content but can look slightly less smooth during fast motion.
This is frame duplication and dropping, not motion-compensated interpolation, so it is fast and predictable and never produces the warping or ghosting artifacts that synthesized-frame interpolation can introduce around fast action or cuts. It is the right tool for matching a delivery frame rate (for example normalizing assorted clips to 30fps for a single upload) or for changing the nominal rate of footage so it plays back faster or slower. If your goal is true slow-motion smoothness from low-FPS source, this tool cannot manufacture that detail.
No. This tool duplicates existing frames to reach the higher rate rather than synthesizing new in-between frames, so the file plays at the target FPS but the motion is not genuinely smoother. True interpolation that invents intermediate frames is not performed.
Each remaining frame retains its original quality. The video will appear less smooth during fast motion, but static or slow scenes look virtually identical, and the file gets smaller.
YouTube accepts 24, 25, 30, 48, 50, and 60 FPS. 30 or 60 FPS are the most common choices. Match your source frame rate when possible to avoid unnecessary conversion.
