Abstract: Interlaced HDTV material derived from 24 Hz film may be successfully converted to HDTV and SDTV progressive-scan formats such as 720P and 480P, using a frame-based process. Such a conversion, done properly, can produce a progressively scanned product with excellent spatial and temporal resolution, and without interlace artifacts or the mixed film-frame artifacts that are the inevitable result of 3/2 pulldown when applied to interlaced video. Proper reconstruction of progressive frames requires assembly of the correct fields, which in turn requires accurate synchronization to the 3/2 cadence of the interlaced source material. This paper will discuss the methods used to convert interlaced video material derived from 24 frame film to progressive and the factors that must be considered in order to make high quality, artifact-free conversions.
