Video File Size Calculator
Enter duration, video bitrate, and audio bitrate to estimate video file size. Check upload limits and storage needs before exporting.
Estimated file size
385 MB
Total bitrate
5128 kbps
Duration in seconds
600s
Actual file size can vary by codec, frame complexity, and variable bitrate settings.
Estimate video size before export
The file size calculator estimates storage needs from duration and bitrate. It helps you plan around upload limits, attachment limits, and available device or cloud storage.
Higher bitrate can improve quality but also increases file size. Including audio bitrate gives a more realistic estimate than video bitrate alone.
This is a formula-based calculator, so no video upload is required. Actual output can differ depending on codec, scene complexity, and variable bitrate settings.
