A sample video of the many videos I have done and put up on Youtube for my classes. Note that this is the only second video I have listed as 'public' with the DWU logo. All these videos for my classes with the DWU logo are 'unlisted' so only students have access to them. I do not monetize these videos and they are the property of DWU (by contractual agreement ).
Note: I don't have the best tools nor do I have the best room space/setup but I make the most of what I have.
I use a Logitech Webcam for video and audio.
I do screen capture & editing using Camtasia. This handy tool has the capability to cancel out noise (requires a tweak). Get the 2020 version here.
Sometimes the live streams on the FB groups are done using OBS Studio (an open-source broadcasting software).
Graphics and video thumbnails are created using a site called canva.com
I use EpicPen to do the on-screen annotations.
I download non-copyright music for the background from tons of sites online.
(Mind you several of my videos have landed me on copyright strikes because music downloaded and used without permission, so be careful when you use music from online and upload to Youtube)
