Home internet is DSL can I work entirely online?

Ann's right on that, as OneDrive has a setup that doesn't work well with video files even if you have fast ISP speeds.

We use LucidLink's "transport" services, with files and projects on an Amazon S3 server in London, our partner in Cape Town SA, I'm in Oregon, USA. LucidLink is one of very few utillity services that moves video files especially in a way that they are usable in an NLE.  and yes, there are costs for using L-L and those servers, depending on how much data you move. Not "high", but ... it does cost some.

But even with LucidLink's amazing service, it takes sustained two-way speeds of at least 250M to be able to work 1080 and some UHD projects.

Mo can Whatsapp phone me he's uploading a folder of media from Cape Town to our Amazon servers in London. Within seconds, the folder appears in my "O" LucidLink virtual folder. A few more seconds, files start appearing.

At that point, I can go into Premiere, and import the files to a project. Premiere thinks they're local. And add them to sequences, start playback ... and the file hasn't even finished uploading from SA yet! Near magical.

Some large files and some long-GOP mp4 files need to be "pinned" in L-L speak, which means downloaded to a drive on the local computer. They still show as in that virtual drive.

So that can work from online ... but again, it's a specialized video file service, using at least 250 Mbps sustained service. 

Most file sharing services like OneDrive and Dropbox see files as files. No matter whether they're spreadsheets, documents, pictures or video files. They just grab segments and 'packet' them and move them in random order.

Video files need to be sent in specific order ... header, and then the file itself sequentially in reasonable chunks. Very different than moving docs or spreadsheets.

One drive is grand for backup but not for editing. Use a local drive.
