How to Do It Manually

Calculate video pixels, megapixels, aspect ratio, and file size. Resolution = width × height in pixels.

Total Pixels = width × height, File Size ≈ pixels × color depth ÷ 8 (in bytes)
  1. Determine resolution (e.g., 1920×1080).
  2. Multiply width × height for total pixels.
  3. Account for frame rate and duration to estimate file size.

Frequently Asked Questions

What's the difference between resolution and aspect ratio?

Resolution: pixel dimensions (1920×1080). Aspect ratio: proportion (16:9, 4:3, etc.).

How much storage for an hour of video?

Depends on bitrate. 1080p @ 5 Mbps ≈ 2.25 GB/hour; 4K @ 20 Mbps ≈ 9 GB/hour.
