FAQ
How is video file size calculated?
Size (MB) = (video kbps + audio kbps) × seconds ÷ 8 ÷ 1000.
What bitrate should I use for 1080p?
Around 8 Mbps for 30fps SDR is a common YouTube upload recommendation; higher frame rates need more.
Is the estimate exact?
No. Variable bitrate encoding and container overhead make real files slightly different.
