#EconTwitter Online teaching: OBS users, what are your recording/streaming set-ups? I'm using a mix of recording (video = 30fps, 1280x720, CRF=20, ultrafast, mp4; audio = 320 bitrate, lagged 180ms for audio/video sync) and streaming (OBS to Zoom using NDI). Any Alternatives?
I also created some png masks, which means you can do zoom like this! I think this will work well for teaching as well as for online seminars! A solution to 16:9 @paulgp! 
What's nice with the OBS-zoom link is that you can seamlessly switch between doc cam, slides, webcam, stata, and other windows in zoom! Step-by-step instructions with common troubleshooting here
My set-up is two displays (2019 MacBook pro and external monitor), IriunWebCam (I use my phone on a small tripod as webcam, free + way better image quality), lapel mic (usb-c), and two dimmable LED light panels (3300-5600K) for lighting.
I'm not doing a light board... my aim is to deliver three courses in a professional, high-quality manner, while still being able to do research (the area of my job that makes up 99% of my performance evaluations) #IncentivesMatter
I'm reasonably tech-savvy and this has taken me about a day (spread out) of experimentation to get the technical details nailed down. This semester is going to be very costly for some folks...
