How many hours of 1080p video fit on a 64 GB SD card?
28.4hours
as 720p, 30 fps (H.264, 5 Mbps), 2.25 GB per hour
A 64 GB card is a common choice for action cameras and dash cams. Many cameras record 1080p at higher bitrates than these; check the bitrate in your camera's manual and use the calculator.
The arithmetic
- 64 GB = 64,000,000,000 bytes (drives and phones are sold in decimal units)
- 5 Mbps × 3,600 s ÷ 8 = 2.25 GB per hour
- 64 GB ÷ 2.25 GB per hour = 28.4 hours
