Perhaps these remarks will be useful....

The first flicker experiments that i conducted with Jack Smith used a projector that did not have either film or a lens, though it did have a shutter.

"The Flicker," at its conception, was organized with reference to a constant flicker at 24 fps. At that time I had no awareness that projectors interrupt each frame once or twice,
with the specific intention of defeating flicker at 24 fps. It was a disheartening discovery for me that "The Flicker" would forever be screened with an effective flicker rate of 48
or 72 fps, substantially beyond the critical flicker frequency (CFF) at which illumination normally appears continuous.

Several times, when opportunity afforded, I was able to modify projectors by blocking one or two shutter openings, so that the actual flicker projection rate was reduced to 24
fps. This was in effect the opposite of removing the shutter, but is perhaps relevant for that reason.

In the mid-70s I devised a way to trigger a strobe from a motorized synchronizer, making it possible to shoot a roll of film as it rolled continuously through the synchronizer,
which was of course fitted with a lens. This arrangement also is the opposite of removing a projector shutter, but in a different respect. Of course, some high speed cameras
operate in a similar way to this.
