I thought filmdint would be more reliable than framestep=2, but I was
wrong. Using framestep=2 and -demuxer lavf (which I was sure I had tried
before in vain), I was able to make it work, but oddly enough, only for
my ultrafast test preset and not the much slower set of options I
normally use.

In sync:

I compared both tests to the original and the former is perfectly in
sync while the other is 50ms or so off (it's not a lot, but it is
noticeable). I can make links to the 3 minute clips (350MB and 535MB
respectively) if someone wants to take a look.
