Important note

If you are considering a change in the max file size, please make sure you have made the necessary preparations and calculations. 

We strongly recommend that IT does a speed test on the access points to determine the capacity in the local network. This will enable you to calculate the max file size the network is capable of delivering simultaneously to a defined number of students.

Bit rate: A video that is 30 MB and 10 seconds long will be percieved as slower to load/start than a video that is 30 MB and 5 minutes long. 
Youtube has help articles that explains more about bit rates: https://support.google.com/youtube/answer/1722171?hl=en

Theoretical example: A 480p video requires 2,5 Mbps to download/stream. If the router has a max capacity of 100 Mbps, this can support 40 simultaneous streams of the video (100 Mbps / 2,5 Mbps).
