How to Use This Calculator
  1. Start by filling in the input fields below. Results update instantly as you type, so you can experiment with different values to see how they affect the outcome.
  2. Resolution — The video resolution. Higher resolutions need more bitrate and storage. Choose from: 720p (HD), 1080p (Full HD), 1440p (QHD), 4K UHD (2160p), 8K UHD (4320p). default: 2.
  3. Frame Rate — Frames per second. Common values: 24 (cinema), 30 (standard), 60 (smooth), 120+ (slow motion). Accepts values from 1 fps to 240 fps (default: 30 fps).
  4. Bitrate — Video data rate in megabits per second. Higher bitrates mean better quality and larger files. Accepts values from 0.5 Mbps to 500 Mbps (default: 8 Mbps).
  5. Duration — Total video duration in minutes. Accepts values from 0.1 min to 1,440 min (default: 10 min).
  6. Once all inputs are set, review your results in the Results panel. Here's what each output means:
  7. File Size (MB) — shown as a numeric value. This is the primary result of this calculator.
  8. File Size (GB) — shown as a numeric value. This is the primary result of this calculator.
  9. 1 Hour at This Bitrate — shown as a numeric value.
  10. Data per Frame — shown as a numeric value.
  11. Suggested Bitrate (H.264) — shown as a numeric value.
