Frequently Asked Questions
At 4K 30fps (typical smartphone bitrate of 60 Mbps), 1 hour ≈ 27GB. At 4K 60fps (100 Mbps), 1 hour ≈ 45GB. iPhone ProRes 4K can reach 5–6GB per minute, making 1 hour over 300GB.
For casual 4K shooting, 128–256GB is adequate. Professional 4K projects with ProRes or high-bitrate settings require external SSDs with 500GB–2TB+ capacity for extended sessions.
4K video generates approximately 4× more pixel data than 1080p. With equivalent compression, a 4K file is roughly 3–6× larger than a 1080p file at similar quality settings.
H.265 (HEVC) offers the best balance of quality and file size for 4K video, achieving similar quality to H.264 at about half the file size. AV1 is even more efficient but requires more processing power to encode/decode.
Very few smartphones support 4K 120fps. Most cap at 4K 60fps. 4K 120fps generates enormous files (potentially 200+ Mbps bitrate), requiring large-capacity and fast-write-speed storage media.
8K video at 200+ Mbps bitrate generates approximately 90GB per hour minimum. Uncompressed or RAW 8K requires even more — potentially 1–2TB per hour. Dedicated high-speed storage solutions are essential.
HDR video metadata itself adds minimal storage. However, HDR typically uses higher bit depth (10-bit vs 8-bit) and higher bitrates to preserve the wider color range, resulting in files 20–40% larger than SDR.
