Frame rate, measured in frames per second (FPS), defines how many individual still images a video displays every second. A higher frame rate creates smoother motion, while a lower frame rate feels more filmic and traditional. Knowing when and how to change a video's frame rate helps ensure smooth playback and seamless mixing of clips from different cameras.
Common frame rates and their uses
24 FPS is the universal motion picture standard. Almost all theatrical movies and broadcast television dramas are filmed at 24 frames per second. It produces a natural motion blur that viewers associate with traditional cinema.
30 FPS is the standard for television broadcasts in North America, web videos, news, and everyday smartphone recording. It feels crisper and more immediate than 24 FPS, making it ideal for vlogs, podcasts, and social media feeds.
60 FPS displays twice as many frames as 30 FPS, resulting in highly realistic motion. It is commonly used for sports recordings, video game streams, and action camera footage where capturing quick movement without blurring is important.
Downsampling versus upsampling
Converting a higher frame rate video to a lower frame rate is called downsampling (for example, going from 60 FPS to 30 FPS). The converter achieves this by systematically discarding extra frames. Dropping from 60 FPS to 30 FPS simply skips every second frame, resulting in crisp 30 FPS video without altering playback speed or audio pitch.
Converting a lower frame rate to a higher frame rate is called upsampling (such as converting 30 FPS to 60 FPS). Because the missing visual data did not exist in the original file, basic converters duplicate existing frames to reach the target frame rate. More intensive AI tools use motion interpolation to generate synthetic frames between existing ones. For general file compatibility and standardization, frame duplication is the fastest and most dependable method.
Why convert frame rates before editing?
If you try to combine 24 FPS footage with 60 FPS footage on a 30 FPS editing timeline, your video editor must make real-time decisions about which frames to duplicate or skip. This often leads to micro-stuttering during playback. Standardizing all your raw video clips to a single uniform frame rate prior to editing ensures consistent visual pacing across transitions.
How to change frame rate in your browser
The MediaBrew FPS Converter allows you to adjust any video file to 24, 30, 60 FPS, or any custom value you need. Simply upload your video file, choose your target frame rate, and export the file in clean MP4 format. All calculation and file transcoding execute locally on your computer using FFmpeg WebAssembly.
