Good effort.

Think about the skill level of the audience. By definition they don’t know what a overhand knot is and how to tie one for abseiling. So will they understand what capsize means? (demonstrate it) This is true at several other points (what is a fisherman’s, and why not show a ready made fisherman's.)
Colours of ropes similar to each other and to table.
I would do the knot etc. and show benefits, only then mention any issues.
What do I do if the ropes are different diameters?
List benefits of possible knots in a table – with pull strengths
Why not show how easily the knot passes over and edge. And how quick to tie and untie compared to other knots.
Vid doesn’t show how you use it, i.e. threaded in a rap
Count how many seconds of the vid is a vid, not a radio transmission. i.e. in what fraction do we gain from it being a video. 90% is just talking and the video doesn’t add. Asking someone to watch your hands in motion but not doing anything for 4 mins is a big ask. This could be filled with the knot in use. Or some the stuff mentioned above.
Units: pounds/feet? Is this for a US audience?
Embed text and arrows on the video. E.g. tail length a two headed arrow showing the length <------40cm-------> so those who don’t have English as a first language can all benefit.
I think you will need so of it shot outside, in use, then back at the table.
Hope that helps and good luck with the project.
