Agfa came up at the end of the S-8 era with their "Family" cine-system:
A most simple Super-8 camera that got two buttons, one for cine- and one for still-photography (single frame exposure). The appropriate (8x10cm screen) projector would freeze at a still-frame. One model of that projector also had the ability to make a Polaroid print of the same size from that still.
It was no succes. Not necessarily due to the tiny film image.
