Youtube Livestream

Not sure about Zoom --> YT but I suspect you might not get the same resolution that you can get from a direct RTMP stream to YT from your PC via OBS.
As for the delay, it would mostly be on the YT side. There are options on the YT Studio portal when you setup a stream on latency.  More delay = more buffer = more stable. If you have little delay/latency you are more vulnerable to  drop off.

Hope this help

I tried both OBS as well as the direct RMP streaming option. Both had a delay, so it makes sense it would be on YT's end. OBS seems more suitable if you're doing an advanced presentation, but I wanted to go directly from Zoom to YT so I could use the drawing tools as well as the recording functions of Zoom. My only problem I'm running into is a 15 s delay between Zoom and YT.
