Ohkay, this actually changes a lot of things. o.o
Looking at your eyes more clearly, they seem Se/Ni.
You still seem to have Fe/Ti, so you're some type of Ti/Fe/Ni/Se type. But I still don't think Ti is your dominant, nor is Fe. Seems to be either Ni or Se.
But I don't have much experience typing people when they're high though.

(no offense, just mean it makes it different). Per example you seem to move rather densely and slowly (like a tall redwood tree swaying in the wind) which is something Ni leads do naturally. But the chemicals could be slowing down your body when you'd otherwise be much more alert and quick to notice/respond (Se-lead).
edit: wait.. I see it now. yes.
you're a very stoned SeTi, who appears more 'zoned-out' than typical.
The way you talk about subjects is in that very Se, sensation-based perspective. For example the irritation with the whole process of video-making, the way you felt 'better' in the last video, and you constantly judge potential actions by their probable or anticipated conclusion. (Ni)
You are constantly either describing what is literally going on around you, or retrospectively explaining how things that occurred, occurred via a causal rhythm. You also do so with a 'technical' consideration of the accuracy of the descriptions you're giving. (Ti/Fe)
But what really gives it away is your smiles at places like 2:42.
I can see them better in this video. When you smile, it rises up on your face quickly (moreso toward the edges of the face) and then suddenly "drops" off your face out of nowhere. Your face immediately resumes a neutral expression and this is due to higher-up Ti's emotional neutralizing. So I'd have to go with SeTi (which theoretically translates to ESTP) but if we're going off of the MBTI's dichotomy-approach (rather than functions-approach) you'd classify, like Architect said, as "ISTP".
