He is not explaining what the heck he's talking about in that one sentence, which must have had some particular application in mind (projection of the film? re-televising the film?).
Let me give you an example of a useful process description:
The EVR (electronic video recording) TV player developed by CBS labs used 8mm microfilm with two images side by side (either two black and white programs or one color program consisting of a monochrome image and a color subcarrier image). The negatives were recorded in an electron-beam recorder with 60 frames per second. The frames were made from NTSC video that was de-interlaced to make 60 complete frames per second. The line structure was carefully dithered to obscure it so that the flying spot scanner in the player did not have to trace particular scan lines on the film.
Now I have described completely a process to use film at 60 frames per second to record 60 field per second video. The single sentence in this book does not give a hint of what process he is describing let alone why it would have a flicker problem.
My suggestion is to ignore his sentence because it contains no decipherable information.
