OBS Recording and Streaming

[Kjhun]

I am a newbie with OBS. I started teaching Math's online to students using my white board and markers recently. I use Zoom and OBS together along with Logitech Brio Web Cam for streaming. I got multiple issues. Firstly, my students did not observe any difference while streaming from OBS or without OBS. When I see myself on the web cam along with whatever I write on the whiteboard, it's crisp and clear but not while it get streamed and recorded. Secondly when I try to record locally; my CPU goes 100% and start blurring and lagging immediately. I tried different settings recommended from various YouTube videos and nothing helped. Sometimes I feel it's my laptop's problem but I don't know for sure what upgrade do I need. I have windows 10 DELL laptop an i3-7100U CPU @2.40GHz with 8GB memory. what I need is quality streaming videos for my students and good quality local recording to share as well. Please suggest.

An i3 is a low-end CPU and if hitting 100% CPU - then lots of things will start to fail. Also, probably a HDD, not an SSD, right? a HDD can be bottleneck, usually a SSD won't be (but depends on other factors)
- So you could follow advice on optimizing OBS for low resource/capability systems.
- you could post an OBS log per the top pinned article in this forum
- or yes, get a more powerful laptop (though, you'll still need to tweak OBS for your environment to get best outcome. so that education won't go to waste)

I wouldn't expect OBS to improve video stream quality (could, depending... ) but OBS is more about being able to composite a video with more options and flexibility than other options.

Your streaming quality, if it looks good locally will be largely depending on computer horsepower to encode and stream, and upload bandwidth to send quality video, and the streaming platform itself. Zoom and others do lots of compression that reduces video quality (fine for free web call with OK looking faces, but certainly not for detail content). Part of that will be understanding Zoom's settings and view options (and associated implications. Ex full screen share, vs screen plus video webcam)

So, part of why you probably didn't get a reply already is
1. folks busy with new OBS version
2. your post doesn't have enough info to provide a good solid response to
Good luck.
