Having worked professionally through the evolution video production from the early 80s to the present day, variously as an editor, videographer director and producer, then switching to making digital video production tools (both live and post) as a programmer, product manager, etc it's hard for me to watch anything and not think about how it was made along with pondering the tooling and workflow.

So, like you, I watched the film (as it was certainly produced on 16mm film) and was surprised by the quality of the graphics, titles and animation. Even the shooting and editing was remarkably good for what's obviously an industrial-grade training film produced on an assembly line. I was especially taken by the fidelity of the full screen title slides featuring soft-edged drop shadows. When I started out in video, the first place that hired me was a tiny hole-in-the-wall studio that produced corporate and industrial sales, marketing and training videos for mid-sized clients on 3/4 inch U-Matic tape. And they still laid out titles by hand a line at a time with a manual Letraset-type machine. The titles we did in the mid-80s didn't look as nice as what these guys were doing in 1953!

The difficulty of editing in the pre-computer days may have helped, in that they probably went to a great deal of effort to fully plan out the content instead of YOLO'ing "we'll fix it in post".
