Nope.  ~30 or 25fps is all you have to choose from.  In the 25fps
(PAL/SECAM) world, all movies are sped-up 4%.

For 30fs (US, Canada, Korea), it's slowed down to 23.976fps, then the

MEncoder can do hard telecine (reencode the video interlaced), or the
-of mpeg muxer can add the telecine flags to the mpeg stream.  Very,
very few programs do this.  If you find a Linux program which just adds
telecine flags, I'd be interested to hear about it.
