[QUOTE=Complication;2075765]This is going to be highly dependent on what output format you are looking for. If you are outputting as H264 or Xvid then it is possible to automatically de-interlace/reverse telecine the video in DVDFab from the GUI. Simply force the framerate to 23.976fps under conversion settings.
As for VOB output (MPEG2), I would like to see DVDFab do simple reverse of soft Telecine but it is no easy task. You save 20% only on hard Telecine content. With soft Telecine, the flags simply request that certain frames are repeated and the file is the same size if you change the flags and fps. The problem is that sometimes the movie has irregular telecine or a mix of soft telecine, hard telecine, and interlaced content which will cause the audio to go out-of-sync or jump.
The only way I’ve been able to consistently get a soft telecined DVD back to the (near) original 24fps progressive Film content and keep the audio in sync is to use a Mencoder script. If your interested in this method then search for PS3 in this forum.[/QUOTE]
You are right about 20% save only in hard telecine but it’s true only when you use a vob passtrough option. When you convert to MP4 or AVI you need a option to do a inverse telecine base on soft and other option to hard telecine. Mencoder has these options and, as I understood, DVD Fab is based on mencoder. If you only set fps to 23.976 the progressive frames will not be restored, unless DVD Fab enable inverse telecine automatically.
