When I do these small factory videos for some reason I often end up in India or Bangladesh. I look for nicely filmed videos with ambient sound rather than cheesy elevator music and/or sales pitches. For some reason that sparseness is the style for a lot of videos out of southeast Asia.
These two videos show small factories that have presses that produce coconut and sesame oil for cooking (although that's a guess on my part, perhaps the oils have different uses). Neither looks even remotely hygienic to me.
