The threshold motion rates that produce edge flicker were determined as a function of contrast, luminance and sampling frequency. A passive filtering scheme, called the Movieola filter, appears to mitigate this artifact. The Movieola filter produces interpolated frames based on a passive two‐tap discrete dissolve. It is simple to implement and therefore relatively inexpensive to manufacture.
