The problem is the shutter value, which is another artistic choice that differentiates "film" from video and will contribute to the choppiness.
Standard for film is a 180degree shutter (half open half closed when capturing). Originally, you had to physically advance the film to the next frame while the shutter was closed. Video would be effectively always open giving you a longer blur. If you shoot at a 60fps instead of 24fps you're going to have 2.5x less blur (and also 2.5x less light). So downsampling wouldn't look right at 24 or 30fps.
