Using OBS with ZoomWhen working together in a tutorial or lab, it is useful to see other students' screens. OBS provides a Virtual camera that can replace the webcam for your Zoom video input. Steps:
- If you are asked to test streaming performance, you can cancel that request and go straight into the program. We can set up streaming preferences later.
- You should have just "Scene" shown under "Scenes" with the comment under sources of "you don't have any sources". Click the + button in the bottom right corner of the "Sources" window to select the thing to show.
- You will be presented with choices of what to add to sources. For the whole screen select "Display Capture" then choose the screen you want to capture. If you want to add a webcam you can also add "Video Capture Device".
- Activate the "Start Virtual Camera" under Controls
- In Zoom, change your camera to the "OBS Virtual Camera".
Using OBS to Record (Not required for the labs)Having set up a scene as for step 1 and 2 above you can also record your screen to a local file using the "Start Recording" button under the controls
This will by default record to "documents/video" but you can change the quality and the location of the saved files in the Settings menu just below Studio mode in the "controls" If you are recording remember to "remux" the recording from the File menu in the top left
This will turn the file from an "mkv" to an "mp4" which is easier to upload and edit with other software.
Streaming with OBSWe will cover streaming a bit later in the year so that you can use the streaming system to connect to the tutors so they can proactively help you even when you by watching a group of students on our internal streaming server which communicates to Discord.
