That is simply not the case. On a sensor with rolling shutter, different horizontal lines of the sensor are exposed at different times. Therefore, really fast moving objects get distorted. This is just how rolling shutter sensors work, and there is no work-around this.
Instead of ripping out all the wonderful mechanics of an old Super-8 camera to create something in disguise, may I suggest to look at a more modern approach to a cinematic Raspberry Pi camera?
