The upload of the recording from VEO camera happens via an internet connection through the Ethernet cable. Therefore, the speed and the duration of uploading depends heavily on the internet connection you’re using.
Make sure that you have sufficient upload speed (20Mbps) and an internet connection from the primary source. Check your upload speed here: www.speedtest.net/. Upload of an average 90 min match with the upload speed of 20 Mbps will take approximately 1,5 - 2 hours.
Note that the speed measured is not entirely reliable, since the connection can vary, due to many reasons and it will most likely not be stable the whole time.
