Originally posted six years ago by antdavisonNZ. The only rendering of the Zapruder assassination footage that looks and feels relatively clean and fluid, partly due to motion-smoothing and partly to the Cinerama-like aspect ratio. This enhancement of the original 8mm, 18fps film, originally shot by the late Abraham Zapruder, was interpolated to play back at 30 frames per second; the slow-motion portion has four interpolated frames for each real frame. Optimum viewing in 1080p HD.
