Frame Rate Details
Frame rate (FPS) determines video smoothness and slow-motion speed.
Common frame rates:
- 24 fps: Cinema standard (movies)
- 25 fps: PAL standard (European TV)
- 30 fps: NTSC standard (US/Japan TV)
- 48 fps: High frame rate cinema (The Hobbit)
- 60 fps: Smooth video, gaming, sports
- 120 fps: Slow-motion (2x slower at 60 fps playback)
- 240 fps: Slow-motion (4x slower at 60 fps playback)
- 480 fps: Extreme slow-motion
- 960 fps: Super slow-motion (some smartphones)
- 1000+ fps: Scientific high-speed cameras
Slow-motion formula:
- Slowdown factor = Recording FPS / Playback FPS
- Example: 240 fps recorded, played at 30 fps = 8x slower
Frame interval:
- Time per frame = 1000 / FPS (in milliseconds)
- 30 fps = 33.3 ms per frame
- 60 fps = 16.7 ms per frame
