I have made several 16mm films with magnetic sound. I have never had
a problem with a venue not being able to show it, though it may be
getting rarer nowadays. Most portable projectors with mag sound run
at 18 and 24, while bigger booth projectors can run at almost any
There is an attachment on the Bell&Howell projectors with mag sound
that allow you to record, so you have to find the projector and the
attachment. Otherwise there are some labs that record on the stripe.
You can also run the film through any recorder that records on
fullcoat, but it is harder to synch.
The sound quality is definitely better than optical.
If you want to record at an odd speed, the best is to speed the sound
up before recording it. For example, I blew up a S8 film to 16mm that
runs at 18fps, and I wanted the optical sound to run also at 18fps.
But I had to provide the lab with a magnetic sound track that runs at
24. So I sped the sound up so at 24 it sounds too fast, like a 33
record at 45, but it starts and ends right with the film. This became
the soundtrack, and when the film is shown at 18, the sound is fine.
