On the Library, we expect a file (that is broadcast master quality) to upload onto The Library within 4 minutes. Please make sure to not change WiFi/internet connection while the video is uploading, or to refresh or close the browser page. If you do lose connection or leave the window, you will simply need to reupload.
If your upload is taking longer than this, this will be down to your internet speed or connection. For example, you might encounter different upload times at different locations (like home WiFi versus office Ethernet connection).
On an 80 Mbit/s WiFi connection, a 500Mb file (a 20second video) will take around a minute to upload. A 1000Mb file (a 60 second video) will take around 1min 37 sec on the same connection.
To find your internet connection speed, please run a speed test: https://www.speedtest.net/
