OBS + Zoom setup help: How to record clean lectures with live drawings, but hide student info?

Hey guys!

I teach live classes on Zoom, but I want to simultaneously record a "clean" version in OBS to use as VOD course material later—ideally with zero editing.

Here’s the goal for the OBS recording:

  • Video: Only my lecture slides. No Zoom UI, chat, or student faces/names.
  • Audio: Only my mic. Desktop audio(student voice) needs to be completely muted in the recording.

Here’s my biggest roadblock:

I annotate and draw a lot while I teach. I realized that if I use Zoom’s built-in annotation tool, the drawings don't show up in the OBS Window Capture because it only grabs the presentation window, not the Zoom overlay.

I want to avoid the nightmare of having to re-record or manually add drawings back in post-production.

Questions

How do you guys handle this?

Is there a specific workflow or plugin combo that allows a true "one take" clean recording with realtime drawings?

I wrote this post hoping to get some help with your ideas or if there are any OBS plugins that might work.

Any advice would be a lifesaver.

Thanks! |:-)
