As I understand it, the file would render from the editor in the normal way but it is then locally sent directly to the EVS to be played down the line. This saves the time needed to send the file across to the playout provider and for it then to be copied across to the main and guard servers, which could take an hour or two in total depending on the duration of the programme. I think they also send it to the EVS a part at a time, before the full edit is complete, which also saves time. From a playout point of view it's not unlike a live programme, with a live source coming in and counts in and out of breaks.
It's not too uncommon for the file to arrive half way though the programme, so you might get parts 1 and 2 as an EVS and parts 3 and 4 from server. In the most extreme cases you might have to start part 1 while still waiting for the editor to send part 4 to the EVS, but that's rare.
Yes - if the show is being edited on an external NLE then that will have render and export time, and the EVS will also have import (and potentially transcode if the NLE and EVS are using different codecs) time.
I know in the world of sport and events highlights, cut on EVS, it's not unusual for a highlights montage to have started to play-out before the final shots have been added to the sequence.

How does EVS work in that kind of situation? Is it like say Premiere in that you have to wait for the sequence to render or is it more real time?
