OBS is great! Huge thanks to everyone who's maintained it over the years. As a side note, I'm trying to figure out how to do live streaming with less intense CPU requirements. My use case is effectively trying to use a Macbook Air to stream high quality video (720p, 30fps). Is there any way I could stream the video raw and encode it on a VPS somewhere? Or is there just a very real hurdle of needing a beefy CPU for an…

I'm actually working on a blog post on the state of streaming live from a browser! WebRTC is...a bit of a monster, especially if you want to broadcast one-to-many.

I've been hacking around with using the MediaRecorder API and piping that through WebSockets to a server that publishes via RTMP. It's definitely rough, and browsers de-prioritizing requestAnimationFrame callbacks when the tab isn't in focus kills things, but it's promising. It runs shockingly well on a Glitch instance for what that's worth.

You need a Mux (https://mux.com) stream key for the demo, but you could quickly edit it to use any RTMP URL: https://mmcc-next-streamr.glitch.me/

OBS is amazing. Half our faculty just went all-out and spent thousands of dollars on some commercial screen recording software. Meanwhile I'm doing my online courses with OBS, and it works beautifully. I have multiple scenes set up in OBS that grab different parts of my screens, and I switch between them with simple key strokes, while narrating on my actions as I do them. It's a very simple, and very effective setup,…

What is a "Scene" exactly?

The B in OBS hints at streaming, but it's also fantastic for purely recording. It's honestly surprising how lacking that space was before OBS. I remember using FRAPS/Taksi a bit, and stuff like Camtasia, but there were all pretty awful to be honesty and definitely not free or open source.

I really like using the recording feature to do sound checks. We go through all of our checks, then I watch the video locally in VLC. That way I'm certain when it goes live it'll sound the way it's supposed to.

I wish more people would do this. Or maybe OBS should have some (opt-out) warnings for when your audio is either unbalanced, too low or too loud. I seen way too videos or streams with bad audio levels.

Can you recommend any resources for learning OBS? My daughter wanted to record some videos of her playing a web-based game. I found the interface to OBS unintuitive. I managed to figure out how to capture a specific area on the desktop, but it was unexpectedly difficult to resize the output to match the input. I found some way of doing it that I can't remember. A few months later I had to do it again and that time I…

try obs streamlabs or twitch studio - they're a lot more beginner friendly and built with OBS if your daughter just wants to record or stream.

I'll say that StreamLabs was better before they changed their monetization model. I was lucky to download and install a few sets of overlays a few months ago that, today, would cost a minimum monthly fee to access.

OBS is amazing. I've used it to record canned demos and presentations for a year or so now, and it just works great on Linux. I even use it to record demos of a wip or partially working feature that I'm working on and attach the video to issues in our gitlab instance to request feedback from stakeholders.

Its feature list is really impressive, but it's great for this kind of simple use case too. Be sure to give it a try and many thanks to the maintainers!

I randomly learned OBS a while ago for doing some twitch streams in the evenings. I'm so glad I did. I run a 6,000 people company during the day and have OBS setup to push into Google Meet. I've done townhall with live on-screen Q/A voting, hosted podcast discussions, done PIP product reviews. I use its video record feature to react to figma prototypes and post the MP4s in the respective channel for discussion. OBS i…

"Presence" in terms of 1:1s should be about listening to, understanding, and empathizing with the person opposite you. Performing "theory of mind," which has nothing whatsoever to do with video quality. This is exactly the kind of aphorism a cold, calculating executive would comfort himself with while orchestrating the hiera…

You're replying to Tobi the CEO and founder of Shopify who recently and very publically posted about 40 hour work weeks and how Shopify lives and breathes work life balance which multiple employees confirmed.

I don't know him from a bar of soap outside of what's shared publically but a cold, calculating executive is about as far from the mark as you could possibly be.

Are there any existing plug-ins for virtual microphone? I want to use OBS'S realtime noise suppression and noise gating in another app (mainly online lecture platform Echo360). I got it working using VoiceMeeter in what seems like a hacky way, but only with high latency so far.

Use Equalizer APO with a noise-reduction VST. This is by far the best option on Windows if you are concerned about latency×compatibility×underruns as a figure of merit. It is far superior to using "virtual audio cables" and a VST host (like Lighthost or SAVI) or voicemeeter. It's not well known, but it really works spectacularly well compared to those other options. For me it never has had any audible buffer underrun…

Do you have any recommendations for VST plugins to use?

This was great advice! The key thing about Equalizer APO is that it does its processing of the sound before the Windows sound API, so any program recording from my mic gets the processed version, and there's no virtual microphone needed (well, the actual microphone becomes virtualised - there's no separate device). I have that all working, and mostly followed this tutorial: https://www.youtube.com/watch?v=J3fBx2ftaBs

I adjusted the numbers for my setup but his were a good starting point.

Please see my sibling comment. The video I linked uses ReaPlugs (https://www.reaper.fm/reaplugs/) and I ended up without needing any explicit noise reduction, just noise gating and some other adjustments.
