So, while we’ve achieved one victory here over NTSC by removing the interlacing artifacts, we still have the unnatural frame rate cadence due to each frame of film occupying different amounts of time. This manifests itself in what is called judder. Pulldown judder is especially noticeable in scenes with long panning shots or credit rolls, but it is always a problem as long as there is motion being captured on film. Judder is probably best described as a hitching motion. A lot of times, it may not even be noticeable if you’ve become accustomed to watching content with judder.
