Enter the pixel width, pixel length, frames per second, and video length into the calculator to determine the video size.

Video File Size Formula

The following equation can be used to calculate the video file size.

VFS = PL * PW *3* FPS / (1024*1024) * T / 1028

  • Where VFS is the video file size (GB)
  • PL is the pixels along the length
  • PW is the pixels along the width
  • FPS is the frames per second
  • T is the total video time in seconds

Video File Size Definition
