Being in the commercial world mostly, I have been working in a modified WFH scenario for years. Granted, it’s a much smaller amount of footage and approvals are “email-able”, but I try to make the process as “dumbed-down” as possible and I am the only editor. Fed-Ex me the files. I cut proxy versions from home and email my first versions. Before Covid-19, take the show on the road to the agency for creative team tweaks (either my gear or their in-house suite). Go to finishing houses as needed. Salt and pepper to taste.
In the Covid world, I do everything at home with no agency visit. Zoom meetings with screen share allow the creatives to comment on an edit. Zoom playing video from FCPX is far from ideal, but it can be slogged through if necessary.
I just finished a doc that had to have color and sound done remotely. Far from ideal (thankfully the director got one color session in before everything shut down, so at least the colorist got a start on the look we wanted). The sound mix approval was a bit of a pain, simply do to environment and lack of quality monitoring.
