Scanning Video Files

Hi 

I find every time I scan my collection trying to get it all into RB video is just freezes  and won't scan any more and I have to restart the software I can't even use it at a gig as I am a Vj and have been for years using other software which has been perfect and I have a late 2017 MBP so no issue regarding performance just wondering any one have this issue or similar as I am trying to get it all done to use with RB DMX too.

Regards 

Gar
