I can see that my computer is retrieving data while I play my video it jumps all the time.
I have a strong laptop and checked with the job's IT department, which believes that it should be able to edit heavy files in PR. But I have big problems editing right now and need your help. I sitting home and work towards VPN.
I would say editing over the network, especially a VPN, is gonna be bad. Like Bryon said, try moving some files local and editing those. If you get better performance, you'll likely need to do that with all your footage. You can also test a proxy workflow, that may work OK over the VPN.
