Rare to encounter this format developed and not split. Double 8mm refers to a film stock cartridge loaded with 16mm film that shoots moving images on one half of the surface, then is reloaded and shoots on the other side. The processing lab then splits the film in half and splices it together for one continuous regular 8mm reel. Here is one example of a moving image work created using unsplit Double 8mm film: Double 8 (2016) by Christine Perschon
16mm film, optical track
A production element where only the image of the optical soundtrack is present near one edge, there is no picture throughout the reel.
