to reproduce
import a bdmv (full disk rip)
auto create bd/dvd title particles
select 1 or more of the created particles
run video analysis
filename is changed to index.bluray;1
particle is no longer playable
I would have thought video analysis & black bar detection should be supported for a particle but if they're not then MC should prevent itself from doing harm (and not process the items)
cf. audio analysis which does work on particles
