I am struggling with this problem for weeks now. How do you guys cope with uploading those huge 4K videos? I have nice streamlined automated system to upload images to stock agencies, but uploading 4K videos requires many times more bandwidth, which isn't available in my area.

I tried some online services that can transfer files from cloud (e.g. Dropbox) directly to agencies' FTP servers. That way, I could upload the videos only one time, the service would then distribute it.

Unfortunately, most of such services are horribly expensive costing around $1 per 1GB of data transfered. Then I found Multcloud.com, which is actually free, but works only barely... I get errors a bit too often and I can't get transfer to SS and FT working properly at all.

I know the best solution is to have unlimited 10Mb fibre optics uplink at home, but those of you who don't have access to such speed, what do you do? Are there any other solutions?

Thank you for your answers.
