抓片式摄影机的摄影频率受到抓片机构的加速度和胶片的机械强度的限制。就目前的工艺水平和醋酸纤维片基的强度,35毫米抓片式摄影机的摄影频率要超过300幅/秒就很困难了。若要再提高摄影频率,胶片就再不能作间歇运动,而必须作连续运动才能使得胶片运动得更快,得到更高的摄影频率。胶片的连续运动避免了抓片机构巨大的跳跃式的冲击和加速 The filming frequency of the filming camera is limited by the acceleration of the film holding mechanism and the mechanical strength of the film. Given the current technological level and the strength of the acetate base, taking 35 frames per second takes more than 300 frames per second, it is difficult. To raise the shooting frequency again, the film can no longer be used for intermittent movement. It must be continuously moved to make the film move faster and get higher shooting frequency. The continuous motion of the film avoids the tremendous jump-type impact and acceleration of the grasping mechanism
