export fps; if export fps != import fps a framerate conversion will
happen in the middle.

changes the behaviour with (some) variable fps conversion

this also explain why we have both --export_fps and --export_frc (even
if the latter could be removed...)

you can find a fps/frc correspondence table on the transcode man page
right below the text you've pasted (format: frc fps)

Nothing of listed since it is a non-standard format AFAIK

I think 10 fps (frc=11) or 5fps (frc=10) should be good.
