Will lowering the frame rate make my video look choppy?

Converting from a higher rate to a lower one (like 60fps to 30fps) usually looks smooth since FFmpeg drops frames evenly across the timeline. Very fast motion can show slightly more visible stepping at lower frame rates, which is an inherent tradeoff of fewer frames, not an artifact of the conversion itself.

Does raising the frame rate actually add real detail?

No — converting 24fps footage to 60fps duplicates or interpolates existing frames to hit the new count, it doesn't invent new visual information. True smoother motion only comes from footage that was originally captured at the higher rate.

Why would I lower the frame rate?

Mainly for file size — a 60fps clip stores roughly twice as many frames as the same clip at 30fps, so converting down can meaningfully shrink a file when the extra smoothness isn't needed.

Does audio stay in sync after changing frame rate?

Yes — only the video frame sequence is resampled; playback duration is preserved so the audio track stays synchronized throughout.

Why is the output always MP4?

Changing frame rate requires a video re-encode regardless of source format, so the tool standardizes on MP4 with H.264/AAC for broad compatibility.

What is Video FPS Converter?

Video FPS Converter changes a video's frame rate — how many frames display per second — by resampling the footage to a new target rate, either smoothing a high frame-rate source down for smaller file size, or raising a low frame-rate source for smoother-looking motion. It accepts MP4, MKV, AVI, MOV, and WebM as input and always saves the result as an MP4.

Changing frame rate isn't just relabeling a number in the file header — FFmpeg actually resamples the frame sequence, dropping or duplicating frames as needed to hit the new target rate while keeping playback duration and audio sync intact. Converting 60fps footage down to 30fps roughly halves the number of video frames that need to be stored, which is one of the more effective ways to shrink file size for footage that doesn't need its original smoothness.

The whole process runs inside your browser via FFmpeg WebAssembly, so your clip is never uploaded anywhere.

Looking to reduce file size more broadly, not just frame rate? Compress Video handles general size reduction.

How It Works

FFmpeg's fps video filter resamples the frame sequence to the target rate — frames are dropped when converting to a lower rate, or duplicated (or interpolated by timestamp) when converting to a higher one — then re-encodes the result as H.264 video with AAC audio, keeping playback duration unchanged so audio stays in sync.
