4K UHD Video File Size Reference Table
3840x2160 Resolution| Platform / Standard | Video Bitrate | Size / Minute | Size / Hour | Quality Tier |
|---|---|---|---|---|
| YouTube 4K UHD (60fps) | 45.0 Mbps | 338 MB | 20.3 GB | Standard Web |
| 2.39:1 Cinema Scope (4K 24fps) | 6.4 Mbps | 48 MB | 2.9 GB | Efficient Cinema |
| Client Review Master (4K 30fps) | 65.0 Mbps | 488 MB | 29.3 GB | High Fidelity |

Aspect Ratio & Letterboxing
Cropping your 4K frame to 2.39:1 Cinema Scope (3840x1607) eliminates 25.6% of unused pixels. Because the encoder doesn't have to compress black bars, encoding at 6.4 Mbps yields higher visual data density per pixel than standard 16:9 at the exact same file size!
Modern Codecs: HEVC vs AV1
For 4K video, H.264 is inefficient. Exporting in HEVC (H.265) or AV1 saves 40% to 50% in file size with identical visual sharpness.
