Approximate File Size and Bit Rate Calculator

Bit Rate:
File Size:

bitrate: pxw*pxh*depth*fps*1024 = kbps
video-pixel-width * video-pixel-height * video-colour-depth * video-frame-rate * video-time-multiplier / video-size-prefix / video-size-divisor

pixel width x pixel height x colour depth (in bits/second) = bits/frame (divide by 8 for bytes per frame)
kibibytes/frame x frames/second = kibibytes/second (uncompressed)

VIDEO:

Uncompressed Video:
(pixel width x pixel height x colour depth [bits]) / 8 (bits/Byte) = Bytes/second

1080p:
1920 * 1080 * 24 * 30 / 8 = 186624000 B/s ~= 177.98 MiB/s ~= 625.71 GiB/h

720p:
1280 * 720 * 24 * 30 / 8 =

AUDIO:

Uncompressed Audio (per channel):
(bit depth [bits] * frequency [kHz]) / 8 [bits/Byte] = KibiBytes/second

24 b * 96 KHz / 8 b = 288 KiB/s ~= 1036800 KiB/h ~= 0.99 GiB/h
