Showcase: Underactuated robotics
Camera:
Set up a camera to record the lecturer plus one full board. If working, use a wireless microphone and plug into mic input on camera. Connect camera (HDMI, possibly usb3) to streaming computer.
Presenting Laptop:
Connect with streaming computer (HDMI).
Youtube channel/account:
Activate for streaming (24h authentication time).
Streamlabs OBS:
On stream computer:
Start Streamlabs OBS
In Streamlabs OBS login to youtube channel
Setup scenes:
Add sources (Microphone, External Display, External Camera)
Check sources (video yes/no, sound yes/no)
Resize camera sources to your liking:
One scene where presenter/blackboard is in focus
One scene where slides are in focus
- You can switch between these scenes when you are live by just clicking on them
- Check your mic’s volume and adjust such that it stays close to hitting the orange region
Hit “Go Live”, streaming will start immediately
- Alternatively schedule stream, then hit go live
Students can ask questions in live-chat.
- Stop stream when done.
This will live stream your lecture online immediately. A recording of that livestream is automatically available on your youtube channel ~10min after you finished streaming. No post-processing necessary.
Of course in a simpler setup you can stream from your own computer, with only slides etc.
Never heard of Streamlabs. Interesting. I like this. Thanks for the recommendation.
It is a great free tool - I use it all the time for live webcasting. There are some effective scripts that allow you to start and stop both live and recorded jobs automatically. We use to usb 3 to capture video and audio. Let me know if I can help - ktierney@mit.edu
