Text materials are generally superior to video because they:
  • are faster to create and edit
  • uses less disk space and network bandwidth
  • is easier to search: Ctrl + F on the browser and off you go. And then grep if you have superpowers.
🔗
Only produce video material if:
  • it shows an experiment, physical technique, natural phenomena or location that is of interest. See also: Section "Videos of all key physics experiments"
  • it gives fundamental geometric insight on the subject
  • you are filming a human transmitting their passion about the subject, and the speaker is amazing, and does not speak for too long
🔗
Never create videos of people just speaking hardcore content for long amounts of time.
🔗
If you have to use videos, make them as short as possible, and index them with a textual table of contents.
🔗
Also consider using sequences of images or GIFs instead of videos, since those are cheaper.
