What is frame rate (FPS)?
Short answer
How many individual images ("frames") a video shows per second, measured in FPS. 24, 30 and 60 are the common values.
Key takeaways
- Frame rate is how many still images a video shows per second (fps).
- 24 fps looks cinematic, 30 fps is standard for social and phone video, 60 fps suits fast motion and games.
- Upload at the frame rate you recorded; YouTube asks for exactly that.
- YouTube, the Instagram API and the TikTok API accept up to 60 fps.
Frame rate (FPS) explained
24 FPS is the traditional cinematic rate and reads as slightly more "filmic." 30 FPS is the standard for most social video and screen recordings. 60 FPS can look smoother for motion and gameplay and may need more bitrate to preserve detail. It does not automatically double file size: at the same total bitrate and duration, file sizes are similar.
Mismatched frame rates cause stutter when footage from different sources is combined without conversion - a 24 FPS clip cut into a 30 FPS timeline either judders or needs frame interpolation to smooth out.
How frame rate creates motion
Video is a sequence of still pictures. Shown quickly enough, the brain merges them into continuous movement: motion starts to look fluid from roughly a dozen frames per second, and keeps looking smoother well beyond 60. There is no fixed "frame rate of the eye", which is why 120 Hz phones still feel smoother than 60 Hz ones.
Why 24, 25 and 30 fps became standards
- Silent films ran at roughly 16 to 24 fps, often hand-cranked, so speeds varied.
- When sound arrived in the late 1920s, the soundtrack needed a constant speed, and 24 fps became the cinema standard, the lowest rate that gave acceptable sound and motion while saving film.
- Television tied its frame rate to mains electricity: 30 fps (60 fields) in 60 Hz countries and 25 fps (50 fields) in 50 Hz countries.
- When NTSC added color in 1953, the rate was nudged to 30000/1001, about 29.97 fps, to avoid interference, which is where 23.976 and 59.94 also come from.
Frame rate, shutter speed and motion blur
Frame rate is how many frames are captured each second; shutter speed is how long each one is exposed. The 180-degree rule sets the shutter to about half the frame interval, 1/48 or 1/50 s at 24 fps and 1/60 s at 30 fps, which gives the natural motion blur viewers expect. Faster shutters make movement look choppy and staccato, the look of action scenes in some war films; slower ones smear it.

Common frame rates and where they come from
| Frame rate | Origin | Typical use |
|---|---|---|
| 23.976 / 24 fps | Cinema | Films, music videos, the "filmic" look |
| 25 / 50 fps | PAL broadcast (Europe, much of Asia and Africa) | TV and video shot where mains power is 50 Hz |
| 29.97 / 30 fps | NTSC broadcast (Americas, Japan) | Phone video, vlogs, screen recordings, most social video |
| 59.94 / 60 fps | NTSC high frame rate | Gameplay, sport, fast motion |
| 120 fps and above | High-speed capture | Slow motion: played back at 24-30 fps it slows action 4-5× |
Frame rate, bitrate and file size
Frame rate does not set file size on its own; bitrate does. At the same bitrate a 60 fps file is the same size as a 30 fps file, but each frame gets half the data, so detail suffers unless you raise the bitrate. That is why platforms recommend higher bitrates for high frame rates.
Slow motion works by recording more frames than you play back: 120 fps footage placed in a 30 fps timeline plays four times slower while staying smooth.
Frame rates platforms accept
| Platform | Accepted frame rates | Source |
|---|---|---|
| YouTube | 24, 25, 30, 48, 50, 60 fps common; others accepted | YouTube Help |
| Instagram (API) | 23-60 fps | Instagram API spec |
| TikTok (API) | 23-60 fps | TikTok Content Posting API |
Frame rate vs refresh rate
Frame rate belongs to the video; refresh rate (Hz) belongs to the screen. A 60 Hz display shows 30 fps by drawing each frame twice, but 24 fps does not divide into 60, so frames are held unevenly (3:2 pulldown) and slow pans judder. 120 Hz screens can show 24, 30 and 60 fps evenly. TV "motion smoothing" invents in-between frames, which causes the "soap opera effect" on films.
Which frame rate to use
| Content | Record at | Why |
|---|---|---|
| Short-form talking, vlogs, tutorials | 30 fps | Smooth enough, half the data of 60 fps |
| Cinematic or music video look | 24 fps | Film motion and blur |
| Gaming, sport, fast action | 60 fps | Clear fast motion; YouTube and the Instagram API accept up to 60 |
| Slow motion | 120 or 240 fps | Played back at 30 fps it slows 4× or 8× |
| 50 Hz countries (Europe, much of Asia and Africa) | 25 or 50 fps | Avoids flicker under local lighting |
How to change a video's frame rate
- Set it before recording: on iPhone, Settings > Camera > Record Video; on Android, in the camera's video settings.
- In an editor, match the timeline to the footage. Converting means dropping or repeating frames, blending neighboring frames, or synthesising new ones with optical flow (Premiere Pro, DaVinci Resolve), which looks smoothest but can warp fast motion.
- Never upload a converted rate if you can avoid it: YouTube asks for video in the frame rate it was recorded.
Frequently asked questions
What does frame rate mean?
Frame rate is the number of still images (frames) a video shows each second, written as fps. A 30 fps clip is 30 pictures per second; a 10-second clip at 30 fps holds 300 frames.
Is 30 or 60 fps better for social video?
Upload at the rate you recorded: YouTube asks for content "encoded and uploaded in the same frame rate it was recorded". 60 fps makes fast motion and gameplay smoother; talking-head video gains little over 30 fps. Higher frame rates need more bitrate for the same quality: YouTube recommends 12 Mbps for 1080p at 48-60 fps versus 8 Mbps at 24-30 fps.
What frame rates do YouTube and Instagram accept?
YouTube lists 24, 25, 30, 48, 50 and 60 fps as common and says other frame rates are also acceptable. The Instagram API accepts reels, stories and videos at 23-60 fps.
What is the difference between 29.97 and 30 fps?
They are the same rate for most purposes. 29.97 (exactly 30000/1001) comes from NTSC broadcast and is what many phones and cameras record when set to "30"; 23.976 and 59.94 are the matching versions of 24 and 60. Keep the exact value when you edit, or footage drifts out of sync with audio over long takes.
Why does my video stutter after export?
Usually because clips at different frame rates were mixed without conversion (24 fps footage in a 30 fps timeline repeats frames unevenly), or because interlaced footage was not deinterlaced. YouTube gives the example of deinterlacing 1080i60 to 1080p30 before upload.
What frame rate does TikTok accept?
TikTok's Content Posting API accepts 23 to 60 fps. Upload at the rate you recorded, usually 30 fps; 60 fps suits gameplay and sport.
Does 60 fps make a bigger file?
At the same quality, yes, though usually well short of double, because consecutive frames are very similar and compress well. At the same bitrate the size is identical but each frame gets less data and looks worse.
