| Feature | Film | Video |
|---|---|---|
| Appearance | smooth, soft edges, ‘organic’, grainy, extremely high effective resolution - scales well on very large displays | sharp, images are divided into pixels, giving them a fixed resolution - scaling will introduce artifacts |
| Price | expensive | inexpensive |
| Frame rate | 24 fps | 30 fps (NTSC), 25 fps (PAL) |
| Color model | subtractive | additive |
| Dynamic range | high - details in scenes that range from bright sunlight to dark shadows are captured better | low |
