Having Zoom built-in is fantastic. Much easier to work with it natively in vMix than ZoomISO, which we have been using. Calls have been very stable (did 4-hour call in production recently with no probs).

After playing around for a while, I have come across a two things that may make it slightly more difficult for some to migrate from ZoomISO to vMix native Zoom.

1) No NDI output of the Zoom participants. Of course you could set up a Zoom input as a vMix Output, but we're already using all 4 outputs various returns, etc. Not sure if there is something that inherently prohibits it, but it would be great to have Zoom inputs available for individual NDI outputs (like vMix call, cams, etc.).

2) ZoomISO has some options on what to do when caller drops (currently it seems vMix Zoom just freezes the last frame on an input that drops, at least for me). Would be nice to have option to go to black, go to alpha, or placeholder image like ZoomISO.

3) I haven't been able to connect to meetings that have a vanity ID (personal meeting room using the room name for instance) - it seems to only take meeting ID as a number, not the vanity name.

4) Having ability to delay video on each zoom input would be most welcome too (mentioned previously)

Anyhow, so far so good - it really is MUCH easier and cleaner to use than ZoomISO (which is a good product, but has some quirks). Really #1 and #4 above would be the biggest pain points for us.

Bummer re: point #1. FWIW, we have 0 performance issues at all - 4K/30p production with 90+ inputs (around 25 are NDI most of which are 4K), all 4 outputs via NDI, multiple SRT's out, Zoom inputs, etc. etc.

Resizable Bar required or it would be a disaster. NIC on vMix and our LAN is 50 Gbit fiber.

I get we're obviously an outlier as far as specs go. But I would think it could be done on our system (it's not even breaking a sweat).
