The Super 8 format had two major disadvantages: firstly, the fact that the film, embedded in the plastic loader, did not ensure perfect flatness in image quality and stability, making the format obsolescent compared to its predecessors. On the other hand, the second flaw concerned a question of appeal on the part of amateur filmmakers. Many amateur filmmakers saw the Super 8 format as an oversimplification of shooting techniques compared to other formats. In order to have access to more advanced techniques, a family man had to have a budget that allowed him to buy high-end Super 8 models, as the basic model did not allow him to experiment with the practices that were possible with the earlier formats. In addition, Kodak's desire to replace the 8mm film stock with Super 8 film led several filmmakers to abandon the practice.
