It wouldn't work for that type of video. As far as I've seen almost all tutorial videos on Youtube have a fixed tab bar though. I'm using it only for learning guitar (i'm a beginner).
Not to rain on the parade but my (er...considerable) experience has been that the videos you end up watching to figure out non-trivial songs do not have tabs at all. The teacher generally describes finger positions one finger at a time visually, or will describe fingering as "it's a D chord shifted up to the 7th fret" etc. E.g Uncle Stu -- no tabs, 12-Foot Chain guy has a sketchy tab once in a while, Shutup and Play guy -- no tabs, Jon MacLennan, Justin, Marty (cool Marty) puts up pencil tabs here and there, other Marty (hat guy) does not, etc. I haven't heard Rick Beato play in a long time but I don't remember him putting up tabs either.
Heck I'm going to say it: tabs actually aren't the medium you want anyway. After getting up and running on guitar, players know what all the chords look like so only need the names with perhaps the fret position as a guide to the voicing.
