Hi! Thanks for taking another stab at this. 120fps is indeed much better for this kind of work.
It looks like you’re swiping the downstroke string changes here, which you can now see thanks to the higher frame rate. I can’t say if this is what you were doing in the previous clip or not given that you’re playing more slowly here. In general, be careful about comparing different speeds, since your technique may change. Assuming you’re looking for a technique that works at all speeds, try filming some attempts that feel fast to you, regardless of what the tempo actually is (i.e. just “go fast” by feel sans click) and see what that looks like. At faster speeds especially, try to move the camera a little closer, so you can see string contact more clearly. This framing (i.e. angle) is great, you can keep that, just pull in a little tighter.
Despite the swiping I’m in the camp where if it sounds good, it is good. So if the line you are playing is only clearing certain string changes and not others, but the muting takes care of it, then so be it. Also, the actual motion in this second clip looks like a double escape wrist motion which in theory can do these kinds of string changes without swiping. So it’s possible that you can clean these up now that you know how to film yourself. Either way if you like what you’re doing, then just double check and make sure it works at all the speeds you need.
More generally, if your primary question is what technique you are using, then it all boils down to which pickstroke type you’re seeing on video (usx, dsx, or dbx), and which joints are actually moving to create those. Because that’s what every picking technique boils down to ultimately - some kind of joint motion that produces a certain kind of pickstroke.
Nice work here.
