This is not some magic setting that will make nice movies. Note that a 
"periodic molecule" is different from just normal PBC. Periodic 
molecules are "infinite" molecules like sheets, nanotubes, etc. that 
have bonds between central image atoms and periodic copies of atoms. If 
you needed such a setting and did not use it, likely your simulation 
would have collapsed.

Many of the normal trjconv routines could likely help here. Accounting 
for PBC effects like these is a standard first step in post-processing 
any trajectory.
