Frequently Asked Questions
How to estimate video file size?
Video file size ≈ Bitrate × Duration. 1 hour of 1080p video at 10 Mbps = 10 × 3,600 / 8 = 4.5 GB. 4K at 35 Mbps = 35 × 3,600 / 8 = 15.75 GB per hour.
How many photos fit in 1 GB?
~500 photos (2 MP JPEG at ~2 MB each), ~200 photos (12 MP smartphone at ~5 MB), or ~50 photos (24 MP DSLR RAW at ~20 MB). Compression and quality matter.
How many songs fit in 1 GB?
~250 songs at 128 kbps MP3 (~4 MB each), ~125 songs at 320 kbps MP3 (~8 MB), or ~35 songs in FLAC lossless (~30 MB). A 4-minute song at 128 kbps ≈ 3.8 MB.
