How to Use This Calculator

Enter Resolution, 720p (HD), and 1080p (Full HD).
Set 1440p (QHD), 4K UHD (2160p), and 8K UHD (4320p).
Adjust Frame Rate, Bitrate as needed.
Review File Size (MB) and File Size (GB).
Use 1 Hour at This Bitrate (GB) and Data per Frame (KB) to inform your decision.

How the result changes with Bitrate

Resolution: The video resolution. Higher resolutions need more bitrate and storage.
Frame Rate: Frames per second. Common values: 24 (cinema), 30 (standard), 60 (smooth), 120+ (slow motion).
Bitrate: Video data rate in megabits per second. Higher bitrates mean better quality and larger files.
Duration: Total video duration in minutes.
