Or you’re simply curious about expanding your tech skills for teaching. Or you may be fairly new to Zoom, and though you’ve traditionally incorporated various source materials into your teaching, haven’t found a way to really replicate the experience for students virtually. You may already be using Zoom, but finding the transitions between class materials via screen sharing are just too clunky. Produced using the methods described in our “How to Use OBS and Zoom for Online Teaching” guide, the video below showcases what can be done with OBS – hosted by CRDT Multimedia Producer Greg MacDonald: OBS allows users to seamlessly switch between various digital inputs while sending a single stream to students via Zoom. Zoom “sees” the output of OBS as a webcam, while you control the changing/mixing of inputs using OBS. It eliminates the need to share your screens and windows in Zoom thereby eliminating those awkward transitions from one Zoom view to another. ![]() – on their computer and feed them all as a single stream to Zoom. The source is clipped using this filter and then scaled elsewhere.OBS Studio (Open Broadcaster Software Studio) is a free, open source application that allows users to switch between various digital inputs – webcams, tablets, browser windows, documents, videos, etc. If you're curious how it all works, take a look at the Filter the source – you can see the entry there ZoomCrop. And with the follow hotkey, the section also follows the mouse. The use is pretty trivial: just start the zoom with your hotkey and you'll only see a section of the desktop, just bigger. ![]() Tip: If you want to use the script for multiple sources, simply copy the Python file and add it to OBS again under a new name. The hotkeys are also from Zoom and Follow So put down Edit/Preferences/Hotkeys for the two points Enable/Disable Mouse Zoom and Enable/Disable Mouse Follow abbreviation. Now only two hotkeys are missing to be able to switch the zoom and follow functions on and off. This ensures that the source is always within this fixed size. The you still have to transform, via the context menu: Calls the dialog Transform/Edit Transform up, sits Bonding box type on Scale to inner bounds and Bounding box size to the size of yours Canvas (read under Settings/Video). In the script settings, the source is particularly important To the Understanding: If your monitor has a resolution of 2000×1000 and the zoom window is 1000×500, the magnification will be 2x. That Zoom Window Width/Height you set the resolution of the zoom window. Set down here zoomsource the source from your current scene to zoom in on – for example a screen capture. You will then see the description and options directly. In OBS you must now use this script tools/scripts/scripts/ add about the small plus button. ![]() But Attention: Even if GitHub specifies a Python file there, the usual "save target as" does not work! You either need to clone the repository or just copy the script content to a local file. You only need the script to be found there zoom_and_follow_mouse.py. Now you can use the script Zoom and follow install yourself. You do this in the terminal with: pip install PyWinCtl Now you must PyWinCtl install, a tool to be able to access required information from other windows under Windows. C:\Users\%USERNAME%\AppData\Local\Programs\Python\Python39) and enter it in OBS Tools/Scripts/Python Settings/Python Installation Path. Mind you, this is about Windows! Installed first Python Then copy the installation path (e.g. A small open source script makes it possible. Of course, this can be done with external tools, including Windows' own, but as an OBS-internal function it is more convenient and much more reliable. And this should ideally follow the mouse pointer. If details are to be recognizable and texts legible, a little zoom is needed from time to time. Screen videos are usually about specific points on the desktop - individual buttons, specific graphics, options or, of course, text.
