Truetime®: An Alternative Approach to the Marriage of Film and Video
Production values for a video derived from a 24Fps film master differ between 50fps and 59.94fps derivations. Normally, the 50fps derivation is speeded up by 4%, producing timing discrepancies for the video content and pitch problems for the audio. The 59.94 derivation contains the motion artifacts associated with the 3:2 pull down process. — This paper explains that if the film material is shot at 25 rather than 24 Fps and a modified pulldown sequence is used, the timing discrepancies and pitch problems are removed from the 50fps derivation and the motion artifacts associated with the pulldown process are reduced in the 59.94 derivation.
