I have nothing against purely aesthetic vids; ‘Ode to the 2 hit Combo’ was awesome even if I dont play half of the games on it. But that’s setting the bar high for any damn combo video.
Take the ‘How to play Team Mike Z’ videos for example. Pretty well done set of videos and lots of good stuff to learn, but I still think a transcript would have good to see. Take for instance the part showing Tron’s guard breaks in the corner. For the life of me, I don’t know when to press the assist button on those. Ditto for any assist combo I see that doesnt start out pressing the assist in the beginning ‘short short psylocke’ style. Now, yes, I could figure it out with a little bit of time in training mode, but tips on when to do it are damn helpful. Compare that to the Twelve video when Thongboy described the 540 degree motion to get a SJC xx air dive super. That was damn helpful.
That’s one end of the ‘beginner friendly/useful’ spectrum. The other end if the pure exhibition combo tutorial, like the ones that require glitch setups like the MvC2 ones that have 2 characters being controlled. I still dont know how thats done and dont really care. It’s just to look pretty.
There are a lot of vids for a lot of games that show off complex skills and execution. It’s easy to get into a mindset and say ‘If you don’t understand what I’m showing you, then you’re not at a level yet where it would do any good.’ It’s a cop out. Just by explaining it, you open it up to be usable by 3x the number of viewers and up everyones game just by having a text file somewhere (not even in the video itself) that explains ‘1:15 by delaying the last two hits of the ROM in the corner, mags can land just a frame or two before Sent and can c.rh into the corner just before sent lands. The odd hitbox of the slide and sent’s hitbox makes this unblockable, resets the combo counter, and allow Mag to continue the beatdown. Done properly, Sent can’t block in any direction.’ (random MvC2 bullshit pulled out of ass. I dont know of any such thing.) Without something like that, most non-pro mvc2 people will think ‘tink tink tink tink, anuther mags beating up a sent, whoopty do’. Sure, if the watcher doesn’t know how to ROM, it may not be immediately helpful. But it helps them understand, and gives them more of a reason to get better, instead of ‘damn, I’ll never be good enough to play, why bother? This shit doesnt make any sense.’ There is an advaced tactics video, the one that shows cable’s counter to AHVB against HSF. Sure, I can’t do it reliably, but I understand it because it explained it. Same with using pushblock for less blockstun so you can counter various things. Same with how a teched throw puts them in regular jump state so they can be guard broken. Good shit to know, each taking up 10 seconds for an explanation page, and a whole bunch of examples afterwards without words. Without the explanations, it would have made no sense. Ditto the quick explanation showing the unblockable exploding eyes when Shuma DHC’s.
To me, a usable video is 10x better than an exhibition video. Ode to a 2 hit just happens to be 100x better than any vid, giving it quite an unfair head start 
I’d also like to see more Strategy in vids. Tactics are good, but Strategy wins game. Buktooth talks about it in his CvS2 FAQs (Stategy for Iori: get to point blank rage. Strat for Morrigan: Knockdown) and the game strategy is described for each character in the Alpha Anthology strategy guide.
