Required upload speed: how fast must your connection be?
Know the file size and your deadline? Calculate the sustained upload speed needed to finish the transfer in time.
Calculate it
How to use the result
Enter the video file size in decimal gigabytes, the deadline in hours, and an expected efficiency percentage. The result is an estimate of the sustained internet upload speed you need, not the highest number seen in a speed test.
Worked example: 20 GB in two hours
A 20 GB recording contains 160,000 megabits. Spread across 7,200 seconds, that is 22.22 Mbps of useful throughput. If you expect 80% efficiency, you would need approximately 27.78 Mbps sustained upload capacity.
Why uploads miss deadlines
Bandwidth can fluctuate with network use, server limits and time of day. Cloud services may also perform extra processing after the upload completes. If the upload matters, allow a comfortable margin.
Do you know your speed instead?
Use the upload time calculator to estimate duration from your expected speed. Remember that 10 megabits per second is 1.25 megabytes per second, before overhead. Our units guide explains the difference.
Math-based estimates are not guarantees. Values depend on actual average bitrate, container overhead and your network or device.
