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
