Video File Size Calculator: Estimate Size Before Recording

What Is a Video File Size Calculator?

A video file size calculator helps you figure out how big your video will be before you even start recording. Think of it like checking how much space you have in your backpack before packing for a trip. This helps you plan ahead and avoid running out of storage or hitting upload limits.

Understanding the Basics

Resolution is how clear your video looks. Common options are 720p (good quality) and 1080p (better quality). Higher resolution = larger file size.

Bitrate is the amount of data saved every second. Higher bitrate means better quality but bigger files. For example, 5 Mbps (megabits per second) is standard for most videos.

Frame rate is how many images flash per second. 30 fps (frames per second) is normal; 60 fps is smoother but creates bigger files.

Quick Estimation Formula

Here's a simple way to estimate: Bitrate × Duration (in seconds) ÷ 8 = File size in MB. Recording for 10 minutes at 5 Mbps? That's roughly 375 MB.
