Do you -need- to use version 3*? Those options/filters may not exist or have 
the same semantics. In pretty much all cases, you're on your own for old 
versions (although Michael has given some good suggestions). The general 
recommendation would be to use a current build.

Unless there's a difficult reason, I'd put the effort into using v4 instead 
of trying to make v3 work.

*Pre-build versions are available from https://johnvansickle.com/ffmpeg/. If 
you _need_ version 3, try a somewhat later static build from there, it has 
3.3 and 3.4.
