Here’s a second attempt at recording a blackboard style screen recording:
To handle the screen transitions, equivalent to clearing my small blackboard, I switched to using a black background and just moved the text as I filled things up. This worked much better. I still drew with mischief, and recorded with OBS, but then did a small post production edit in iMovie to remove a little bit of dead air and to edit out one particularly bad flub.
This talk covers the product of two vectors, defines the dot and wedge products, and shows how the 3D wedge product is related to the cross product. I recorded some additional discussion of duality that I left out of this video, which was long enough without it.
