Slow-mo factor = shoot FPS / playback FPS. Shooting 120fps played at 30fps = 4× slow motion. 240fps at 24fps = 10×. A 10-second real-time clip becomes 40 seconds at 4× or 100 seconds at 10×.
| Shoot FPS | Play at 24 | Play at 30 | Play at 60 |
|---|---|---|---|
| 60 | 2.5× | 2× | 1× |
| 120 | 5× | 4× | 2× |
| 240 | 10× | 8× | 4× |
| 960 | 40× | 32× | 16× |
Set shutter speed to 1/(2×fps) for natural motion blur. At 24fps: 1/48s. At 60fps: 1/120s. At 120fps: 1/240s. Breaking this rule gives either staccato (faster) or dreamy (slower) motion.
Bitrate scales roughly with frame rate. 4K 30fps at H.264 = ~100 Mbps. 4K 120fps = ~400 Mbps. A 10-second clip at 120fps: 500 MB in H.264. RAW at 120fps: 5+ GB per 10 seconds.
24fps: cinematic, standard for film. 30fps: broadcast TV, streaming. 60fps: sports, smooth motion. 120fps: 4× slow-mo. 240fps: dramatic 10× slow-mo. Higher = more light and storage needed.
