1.
Select your resolution
Choose the resolution you plan to record or export at — 4K, 1080p, 720p, or custom. The calculator pre-fills a typical bitrate for that resolution.
2.
Enter your bitrate
Adjust the bitrate in Mbps to match your codec settings. H.264 at 1080p typically uses 8–16 Mbps; H.265 uses roughly half that for the same quality.
3.
Set the duration
Enter the total recording or clip duration in seconds. For a 10-minute video, enter 600.
4.
Read your estimated file size
The result updates instantly. Use it to check whether your file will fit within vitelnk's free 1 GB upload limit before you start recording.
Why This Matters for Video Creators
Knowing your video file size before you hit record or export saves time and prevents surprises. If you're uploading to vitelnk, a quick check ensures your video stays within the free 1 GB limit — or tells you to enable the 2 GB email tier or 5 GB free trial before you start. For videographers quoting storage or delivery costs to clients, this calculator gives you an accurate number in seconds rather than waiting for an export to finish.
