Hmm... The interesting part there is the "VFR aware filter". I think I can come up with that in Transcode (Avisynth isn't available for Linux). It also didn't occur to me that the target framerate needs to be a common multiple of the component framerates.
There is a very interesting (incomplete?) Transcode invocation purporting to be able to rectify VFR here:
http://www.transcoding.org/cgi-bin/transcode?Tutorials/Framerate_Conversion
It bears a striking resemblance to Fermat's Last Theorem.
I'm certain that will NOT work exactly as stated, but it's probably 90% of the way there. It appears to be doing the 120fps conversion and the subsequent decimation in a single pass!
