To calculate the size of a video file, multiply its pixel resolution by the frame rate and bit depth, then adjust for time and storage units.
The Video File Size Calculator helps determine the storage space required for videos based on resolution, frame rate, and duration. This is particularly useful for planning video recording, streaming, or storage management.
Formula
VFS = (PL × PW × 3 × FPS) / (1024 × 1024) × T / 1028
| Variable | Description |
|---|---|
| VFS | Video file size (GB or MB) |
| PL | Horizontal resolution (e.g., 1920 for 1080p) |
| PW | Vertical resolution (e.g., 1080 for 1080p) |
| FPS | Frames per second |
| T | Video duration (in seconds) |
Solved Calculations
Example 1: 1-Minute 1080p Video at 30 FPS
| Step | Value |
|---|---|
| Horizontal Resolution (PL) | 1920 |
| Vertical Resolution (PW) | 1080 |
| Bit Depth (Assume 3 bytes/pixel) | 3 |
| Frame Rate (FPS) | 30 |
| Video Duration (T) | 60 seconds |
| Video File Size (VFS) | (1920 × 1080 × 3 × 30) / (1024 × 1024) × 60 / 1028 ≈ 5.7 GB |
Example 2: 10-Minute 720p Video at 24 FPS
| Step | Value |
|---|---|
| Horizontal Resolution (PL) | 1280 |
| Vertical Resolution (PW) | 720 |
| Bit Depth (Assume 3 bytes/pixel) | 3 |
| Frame Rate (FPS) | 24 |
| Video Duration (T) | 600 seconds |
| Video File Size (VFS) | (1280 × 720 × 3 × 24) / (1024 × 1024) × 600 / 1028 ≈ 5.2 GB |
What is Video File Size Calculator | Estimate the Video File Size, File Storage, 4K, 1080p, 720p in Megabytes, Gigabytes or Terabytes:
A Video File Size Calculator is a helpful tool for estimating the storage space required for video files based on resolution, frame rate, bitrate, and duration.
It simplifies the process of planning storage needs for videos, whether you’re managing personal footage or professional projects.
This calculator allows users to input details like 1080p at 60fps, 4K video specifications, or desired bitrate and quickly compute file sizes in MB or GB.
For instance, a 1-hour 1080p video at a standard bitrate can be estimated for storage requirements, helping to manage device space or hard drive capacity efficiently.
Moreover, it aids in understanding the impact of compression formats like H.264 or H.265, which influence file size significantly. Whether you’re working with MP4, ProRes, or streaming configurations, this tool provides clarity on how video properties affect file size.
Final Words:
In summary, the Video File Size Calculator is an invaluable resource for predicting and managing video storage needs. It ensures efficient planning for personal or professional video projects while saving time and avoiding guesswork.
