Actually the dancing is rather good, which is besides the point. Whatever the case, I urge you, Jack - you really need to see this film! The setting is a winter woodland rather reminiscent of the Golfers story in Dead of Night - strong monochrome contrasts, very stark and atmospheric. I think the clips are un-edited rushes, hence the false starts and re-shooting from different angles and various disappearances. If you've seen Ring AKA Ringu (Hideo Nakata 1998) it has the flavour of Sadako's VHS footage! As already pointed out, 1929 is very early for sound-film - The Marx Brothers would have only just done The Cocoanuts (sic) at the time when all the cameras had to be in wooden boxes because of the noise they made - shooting through glass, you can see the reflections in many of the scenes! The sound here is pretty good too.

There is an innocence here I admit, but one born of a definite social privilege which seems to under-write the Folk Revival at every turn. This is the sort of thing that feeds back into education, making it into Wavlore as Our Own Good English Country Dancing, which is the very last thing it is. It complex for sure, but ultimately rather fascinating, as is this uniquely, and singularly, beautiful document - however so unwitting, or random, that beauty might be.
