Seems it isn't telecined according to your script, which is exactly what
I thought. Thanks.


While we're on the subject, I have material that I know is telecined at
60000/1001fps and I want it at half that (it's on a network that does
720p at 60000/1001 and the material is originally 1080i at 30000/1001).
-ofps 30000/1001 doesn't work. There's some discussion about 60fps
telecined material on the list, but I didn't quite understand it and I
think it's for getting 24000/1001fps anyway.
