In this clip I describe how to record a lecture with annotations. This is what is needed:
Hardware:
Tablet input device: Wacom One, or XP-PEN Star03 Drawing Tablet, or comparable
decent microphone: Blue Snowball or comparable
Software:
OneNote, to show your lecture slides and annotate them. You can also annotate in Power Point, but I like the extra space you can get in One Note
Screenrecording software, I use Camtasia, but free alternatives are Apowersoft Online Screen Recorder or Screencast-O-Matic
Video editing software if you want to be able to speed up or slow down the recording, cut and slice the video and add narration after the recording. I use Camtasia for that as well, but a free version is Shotcut
