I'm not sure if other cameras behave the same way, but when I get AVCHD clips from my Canon they have serial number names that ALWAYS start at 00001.MTS -- so if I shoot on three cards, I end up with three sets of identically-named clips.
I've been reluctant to rename the source clips -- apprehensive that I may be losing information that's also stored in the associated INDEX.BDM -- is naming the top-level directory the best one can do, organization-wise? Not very pretty, it means I still end up importing multiple 00001 and 00005 clips etc.
Has anyone have a clean way to do some broad-stroke organizing from within PP or the Media Browser? Binning is fine, but a lot of tedious busywork imo.
Check if Canon doesn't provide some sort of importing software.
I use Sony AVCHD. If I just import directly from the card it's 00001.mts, etc. If I import using the Sony software, the clips come in with unique serial # names that include the date it was shot.
It's a huge help if I'm doing a project with hundreds of clips.
