72:25 is Cinerama. My Skyrim videos get close to that (if I have letterbox turned on). Some of them are still just boring 16:9 footage.

Ah, Cinerama. My "Movie Edit Pro" does not offer that as a preset. A Google search turns up a reference to a Psalm, so I thought it was "Biblical Proportions", as in "a flood of Biblical proportions" ...

Which reminds me of Bryce's image size presets, one of which is "Imax". I recall a posted image in that proportion that was just two flashing dots. Took me a while to get the joke, and the poster had to explain it eventually.
