Hey Mohamed,
You are very welcome.
Sadly in your scenario, and I have been there, so I feel your pain:
If you want to work on the original camera files, and they come in big sizes, you will need either time, or a couriered hard-drive/SSD. There is no other way, unless your client is happy to compress the files, or you are happy to work on proxies and let someone else do the final export. That this can be done in its native format without improvement in digital infrastructure.
1) Short of moving, you should have a contingency plan in place in case your current internet breaks down.
As part of that research, you may find a solution that both you, and more importantly your client is happy with. Keep in mind that most of your clients will hire you, for you, as you can deliver quality, and not necessarily because of expensive internet speed only used in moving files around.
Do check wireless options (5G / Space delivered internet) and if there are co-working spaces near by with high-speed internet.
2) If your internet speed is equal to that of a horse pulled wagon, you will not be able to compete in a F1 race. No matter how you dress it up. With all due respect to your client, if they are shooting on an A7, then they are on a lower-budget camera – nothing wrong with that, as it is an excellent camera for specific jobs.
But does not change the nature of your business where you either need to charge for speed in delivery of master, or be given the time to deliver at a lower “file transport” cost.
3) Your article does not show on my browser. But, I am sure that you can control your own internet connection – although some may argue that we have all been hacked in one way or another.
There are still large scale companies, including broadcasters, where the editing suites are not connected to the internet (a pain when updating software and installing new plugins).
My comment about security is the involvement of a local 3rd party with a potential open wifi, that might be fast enough, but not deemed secure.
4) “VPS and RDP” will not change your base problem of working with large files. And, unless you have an established relationship with a host + the necessary technical skills, you may be wasting more time and money than what it will cost to dig a direct 10 Gbps cable from provider to your location.
There are firms offering remote software hosting and files. A quick search got me to https://www.qvest.com/en/cloud-editing – “The enterprise solution for cloud-based editing”.
The key-word is enterprise.
They do offer a demo, which I would encourage you to do.
And, notwithstanding that Egypt in my younger days (maybe still is) was the 2nd biggest, after India, hub for film production. So it would not be unthinkable that any RDP virtual Post-Production supplier would like someone local, with language skills, that can support and demonstrate their goods + do editing work for their clients.
Go fetch – might solve several of your problems 😉
