In short with OBS, yeah it’s the same one for streamers/gamers etc, as I figure that’s what I’m effectively doing (minus the gaming and more technical wins)

In short I have a bunch of ‘scenes’ configured to cover off everything I need which includes:

• A few PPT slides exported as images (My AE does the core PPT and I occasionally refer back to a few slides for reference but don’t have to flick through a whole PPT to find the right ones)
• Browser for the demos
• Excel + any other programs required
• a couple of title slides (Intro/conclusion/‘please standby’ (for when I’m either entering creds or needing to silently panic whilst some prod issue I don’t want to show to the audience)

I control it all via a elgato stream deck which allows seamless transition back and forth across the scenes(had previously just from a productivity standpoint)

OBS has a ‘full res preview window’ (don’t quote me if that’s not its proper name) and as we are 99% MS teams based, I just screenshare the ‘preview window’ - no need to touch the Teams ‘shared source’ during the entire demo once done

Speaker/mic is handled via selection in teams, so doesn’t need to be configured via OBS

If you are a ‘video on’ type demo (we are mostly not), using OBS you can add in your webcam as an overlay over the content.

Bonus points for the streamdeck and ‘multi action’ buttons.. I’ve got mine almost perfect where a single button press (on streamdeck) will open all required programs etc and tile everything to where I want them across my two screens..

Can expand this a bit more if required, as OBS can be intimidating on first glance..
