The number of individual still images a video displays each second. Every frame is a complete picture; played in rapid succession, those pictures create the illusion of motion, and the rate at which they appear determines how smooth or choppy that motion feels to the viewer.
Frame rate is a creative choice as much as a technical one. Cinema standardized on 24 frames per second nearly a century ago, and audiences still associate its slight motion blur with a filmic look. Broadcast television settled on 25 in PAL regions and 29.97 in NTSC regions, a fractional oddity introduced to keep color signals compatible with black-and-white sets. Digital platforms freed video from those constraints, and 30 and 60 have become the everyday rates of the web.
Common Frame Rates and Where They Appear
Most footage encountered in marketing work falls into one of a handful of standard rates, each with its own history and purpose.
| Rate | Origin | Typical Use |
| 24 FPS | Cinema | Film and cinematic brand videos |
| 25 FPS | PAL broadcast | European television and video |
| 29.97 FPS | NTSC broadcast | North American television and older camera defaults |
| 30 FPS | Digital video | Web video, social feeds, background loops |
| 60 FPS | Digital video | Sports, gameplay, screen recordings, smooth motion |
| 120+ FPS | High-speed capture | Slow-motion source footage |
Capture and delivery do not need to match. Filming at a high rate preserves the option of smooth slow motion in the edit, while delivering at a lower rate keeps files lean.
How Frame Rate Affects File Size
More frames mean more data. At a fixed bitrate, a 60 FPS video spends half as many bits on each frame as a 30 FPS video, so doubling the frame rate either doubles the file or halves the per-frame quality. Modern codecs soften the penalty through inter-frame compression, storing only what changed between consecutive frames, but the relationship holds: frame rate is one of the three levers, alongside resolution and bitrate, that determine how heavy a video file becomes. Frame timing itself comes in two flavors, VFR and CFR, which govern whether that rate stays constant through the recording.
Why Frame Rate Matters to Marketers
Every distribution channel publishes frame rate expectations, and matching them avoids both rejected uploads and needless weight. A product page background loop at 30 FPS costs half the bandwidth of the same loop at 60 with no visible difference on a slow pan, and lighter pages protect Core Web Vitals (CWV) scores. Knowing when smoothness earns its bytes, and when it does not, is one of the quiet skills of publishing video that performs.
