Love the beer hunter stuff even more now that traditional brewers are closing/merging/changing etc. Great history!
I wish that the Discovery Channel would re-release these videos on DVD. I wonder if they were recorded in 4:3?
Most likely shot in 4:3
Given that the original footage was shot on film (rather than video) so many years ago...most likely in the 16mm format... it's a safe bet that the aspect ratio of the original footage was indeed 4:3.
However, that aside, if the original film elements were properly preserved, they should yield very high quality without artificial enhancement if transferred to modern high definition video format for re-release. One could only hope though that
if that is ever done, they retain the original 4:3 ratio and avoid the temptation to crop top and bottom for widescreen, unless it is done with great care and on a shot-by-shot basis.
