I use OBS as the recording software for all of my lesson videos (excluding devos which I usually record on my phone). This software is free to download and possesses live stream capability. OBS can also show preuploaded slides (e.g. my lesson sldes) and can display many other sources such as videos, additional cameras, etc. As I stated above, I regularly use this program and have come to love how versitle it is (considering it is free) and have been able to use it in multiple ministries.
