Estimated File Size
How File Sizes Are Calculated
Video file size is determined by bitrate multiplied by duration. A 1-hour video at 8 Mbps produces approximately 3.6 GB. Compression codecs like H.264 and H.265 dramatically reduce sizes compared to raw footage.
Common Video File Sizes
- 1 hour of 1080p H.264 video: ~3-8 GB
- 1 hour of 4K H.265 video: ~15-25 GB
- 1 hour of 4K RAW footage: ~100-400 GB
Common Image File Sizes
- JPEG photo (12MP): ~3-6 MB
- RAW photo (24MP): ~25-50 MB
- PNG screenshot (1080p): ~0.5-3 MB
