When you render (aka export) a video, the output in progress does not display. Only a copy of the original, or sometimes a “not-rendered” screen showing a recent preview or a faded copy of the original.
There is no option to choose the output video as one of the previews so the side-by-side and split views are pointless.
After several attempts with different settings, I noticed that the export list shows a tiny progress bar so I let it run for 4 hours and it turned out that it worked, but there was no indication that it was working and to need to wait 4 to 8 hours to see the result and try again if it was not as hoped was a bit of a sub-optimal workflow.
