Sarah Zedig's video about writing godfeels is a good one imo
Taz (optimistic deulist) also has very good homestuck analysis (and iirc was part of why he was asked to join hs^2?)
technically not videos but I'm pretty sure all of the perfectly generic podcast is up on spotify and internet archive (though internet archive actually has them in the right order lol)
also I mostly like kylemarshiku's "homestuck is good, actually", though I disagree with his conclusions abt epilogues jade (that being that she works better as intersex rep than trans rep) as someone who has talked a few times here abt what she means to me as a trans woman
