I gave Wesley-Knox United Church a whirl this morning, the same church I was starting to attend in person before Covid hit. They are doing a pre-recorded service posted to a Youtube channel.
First off, they have a minister in place. It's a supply, rather than a call, but at least they've got one, now. So he is leading the services.
One thing they are doing differently from some other Youtube services I've looked at is that they are going beyond the sanctuary instead of just doing a service in an empty sanctuary. So the service opens with a family in their living room doing the lighting of the Christ candle, then cuts to the minister in the church's chapel to do the Call to Worship, then to the organist and minister in the sanctuary to lead the first hymn, then to a Sunday School room for the children's time, and so on. The anthem was a couple from the church who do bluegrass music (I've heard them before in regular services) in their living room. So it looks like they get the different participants to shoot their part, then someone is editing it. And the editing seems to be fairly well-done, too, so obviously it is someone with some skills and decent editing software. Oh, and they are adding the hymn lyrics and unison readings as subtitles.
Now, they are also using Zoom for other activities. For instance, their adult education program is trying it for a study of the Bart Ehrmann lecture series "How Jesus Became God" (a Great Courses series, BTW, so you may be able to find it for yourself on Kanopy if your library has it) for 6 weeks in May-June. If it goes well, they will then restart it in the Fall.
